McAfee Security Software Rebooting PCs

April 22nd, 2010

Computers worldwide suddenly went into simultaneous rebooting loops as a result of a legitimate Windows file being mis-identified as a virus.  According to McAfee, a software update posted at 9 a.m. Eastern time on April 21, 2010 is the culprit, affecting corporate users of McAfee’s security software around the world.

Hospitals, schools and government offices were impacted by the glitch, causing a third of the hospitals in Rhode Island to curtail non-trauma ER and elective surgery treatment until the problem was resolved.

McAfee spokesmen said it appears consumer versions of their products were not affected by the update.

Instructions for restoring the quarantined files can be found here.

McAfee has released a SuperDAT remediation Tool to restore the svchost.exe file quarantined during this debacle.

Legacy Windows Support to be Abandoned

April 11th, 2010

For those of you running versions of Microsoft Windows without (what Micro$oft considers to be) current service packs, you are about to be disowned by the Behemoth from Redmond.  Just thought you might want to know.

The versions included in this swift kick to the curb are:

  • Windows XP with service pack 2 (support ends July 13, 2010, along with Windows 2000 Maintenance and Support)
  • Windows Vista with no service packs (support ends April 13, 2010)
  • Microsoft seems to have “a thing” about the 13th of the month…
  • This means you will no longer be able to receive monthly updates, service packs and security fixes from M$oft.

So no problem, you say, I’ll just go download the updates, right?  Sure, if you like to live dangerously.  Read the blog entries on service pack 3 for XP regarding the risks.  Any service pack for Vista is a double-edged sword.  Since Vista is by far the most unstable and unpredictable OS ever released, doing anything at all to it is riddled with risks.  While Vista should have all the service packs you can find for it, the time to install them is ridiculous (about 5 hours for Vista on any given HP machine for reasons we don’t understand) and you can wind up with a machine that is in a reboot / repair loop forever.

Service Pack 3 for XP has caused no end of headaches for some people.  It’s a zero-benefit service pack in our estimation, simply bundling a wad of updates into an SP and shoving a modified version down the pipe to end users labeled a Critical Update.  You are far better off to install it from a disk rather than a download (look for our article on this).

If you are going to install a service pack, BACK UP YOUR DATA FIRST.  Do NOT use Vista Backup to do this (read our blog entry on this as well).  Copy what you need to an external drive manually or download the recommended backup software listed on our Good Things / Bad Things page.

Keep in mind, you NEED the Security Updates for Windows.  You do need to resolve this issue in a timely manner to remain safe.

Critical IE Update Re-Patch Released

November 5th, 2009

On October 13, Microsoft released it’s largest-ever bug fix, containing a critical update to all versions of Internet Explorer.  On November 2, a re-patch of this same critical update was released, applying to all versions of IE from 5.07 to the newest version 8.  This patch is critical for all versions of Microsoft’s Windows Operating System, including their newest, Windows 7.

November 2nd’s fix, targeting MS09-054, October’s update that plugged holes in 4 critical vulnerabilities in Internet Explorer. was triggered by display problems caused by the previous update.  According to a Microsoft spokesman, the problems affected only a small percentage of users.

A Microsoft Support document explains the two issues provoked by the update.  One generates a “Type Mismatch” script error, while the second scrambles web page components.

If you have any doubt about your security or patch status, we recommend you manually run your Windows Updates and download all Security Updates Only.  As stated in other entries in this blog, make sure your Automatic Updates remain turned OFF to eliminate problems associated with badly behaved downloads from Microsoft (IE8 is the biggest offender at the moment, staying just ahead of Service Pack 3 in severity).

Facebook Security Warning

September 20th, 2009

We’ve been telling people this for over a year, even published a security bulletin from AVG to this effect, but apparently never published an actual warning regarding the real risks associated with using Facebook (and MySpace).

Both of these Social Networking sites have been under attack since May 2008 by criminals intent on extorting money from individuals they infect with their Malware (also known as HostageWare, FakeAlert Software).  When your computer produces a warning screen or popups in the lower right corner warning you of infections and an offer to “fix” the problem for $49.95 (up to $89.95 in some cases) it is TOO LATE.  You are infected. You will not be able to fix this yourself.  If you gave them your credit card information you will quickly find your card canceled due to fraudulent activity.  (Call your credit provider card immediately if you have fallen prey to this scam)

This has been the pattern with these brilliant criminals working out of Eastern Europe for over a year now and there are no signs of the problem getting better.  Many people ask “why do they do this?”  ”Money” is the obvious answer.  No legitimate product will EVER pop up on your screen and ask for money to “fix” something wrong with your computer.  These Fake Security / AntiVirus / Performance Tuning / Registry Repair tools are all infections, plain and simple.

  • Just working with very small, easy to calculate examples at the low end of probability for these schemes, let’s say that one of these virus authors gets only 1000 people a day to “bite” on the offer to “protect” their computers.  At $49.95 each, that’s Fifty Thousand Dollars a day.  Pretty good money for sitting around eating Cheetos in your underwear in an (very nice) apartment in Kiev (Moscow, etc).
  • Now factor in the bonus as a result of having all the victim’s credit card information entered during this transaction.  Can you spell SHOPPING?  Our resourceful virus writer is spending your credit card limit in a heartbeat – so fast your credit card company won’t be able to stop it before this thief cashes in nicely on your plastic.
  • But the big payoff is gaining access you your personal identity information stored on your computer.  Credit card numbers, social security numbers, user login information - anything stored or cached on your computer from previous transactions or for your own records can now be in their hands to use as they please.  Identity theft is big business and can ruin your life.

We have disinfected over 250 computers since June of 2008 with one variety or another of these nasty infections.  (Refer to our Bad Bugs List here in the blog for the growing collection of these pests)  Absolutely nothing stops them, as these bugs are reinvented on an hourly basis.  The best antivirus you can buy (AVG) will still not provide 100% protection against these thieves.

We have been recommending to everyone since this problem surfaced to AVOID FACEBOOK AND MYSPACE unless you are using a Mac or Linux-based system, as they are immune to this infection (for the time being).  If you do not heed this warning, YOU WILL BE INFECTED.  Period.  Even the New York Times website was hacked and infecting their readers earlier this month, so it’s not just a Social Networking issue, but they are the primary focus.

“But I never click on anything.  I just check my messages…”  Great.  But no protection.  Most of these infestations are distributed by infected banner ads.  As soon as the ad displays on the page you’ve loaded, IT’S OVER. YOU’RE INFECTED.  It is NOT necessary to click on one of these ads for it to deliver it’s payload.  The criminals actually pay for advertising so they can infect your computer and extort money from you, steal your identity, etcetera.  They also hack user accounts so they can send messages that appear to be from your friends, but actually contain infected links.  It has happened to my friends.

Why isn’t Facebook doing more to protect it’s users?  We recommend you ask them exactly that.  Also, send them the bill for cleaning or reinstalling your computer the next time it gets infected.  See what happens.

And another thing.  Be careful what surveys or “tests” or other cute features or add-ons you participate in on Facebook.  Anything that requires a phone number to be involved will possibly start charging you every month for some infernal news feed while you get junk text messages you didn’t want.  If you are getting these already, simply reply with STOP or QUIT – and they should remove you immediately.  Also, dial 611 (assuming it’s your cell phone) and ask your provider to cancel the service you “signed up for” and refund the charges.  If you get a decent rep, it should be no problem.  If they are not being helpful, demand to speak to a Supervisor.

[Oh, and Google... Did you know these same miscreants are paying for top Google ad placement to sell you infected, fake AntiVirus products?  We've seen them time and again at the very top of the sponsored links in Google search result pages...]

Panda Labs recently uncovered a website that offers to hack any Facebook account for $100.00.  Once they have successfully gained access to your account, everything you have posted in that account is THEIRS.  The result:  Identity theft — YOURS!  According to this website, only 1% of all Facebook accounts cannot be hacked!  Once they have hacked an account, they have full access to your Friends’ contact information and now they can send them infected links or images, ostensibly from YOU.  Nice.

Just say “NO” to Facebook!

Unless you’re using a Mac…
(I know, you NEED your Facebook fix…  I use it all the time, just never from the office where we use all PCs.  Only from home where I use an Apple OS x based computer.

Now for the serious part…

If you have given these clever criminals the money they ask for, call your credit card company immediately so they can start the process of issuing you a new card.  If you have logged into any financial institution within a few days either side of the date when you first noticed the infection or during the infection period, CALL these institutions and have your password changed IMMEDIATELY.  This is a good idea from time to time anyway, but after your computer has been infected it is mandatory.

Avoid Internet Explorer 8 at All Costs!

July 17th, 2009

We commented on IE8 in an email blast awhile back, but now that it’s at the top of the Critical Updates list in Windows Updates, you need to take steps to protect yourself.

Internet Explorer 8, Micro$oft’s replacement for the almost equally-buggy IE7 is responsible for absolutely CRASHING large numbers of Windows XP computers.  We probably get 5 machines a week that are non-functional, won’t load Windows, are completely locked up or just plain S.L.O.W. as a direct result of an IE8 installation.

“But I can just uninstall it if there’s a problem, right?”

Maybe.

And maybe not.

We have found a high percentage of systems where there is no “easy fix” for the IE8 install.  IE is welded into Windows.  This is the basis for the EU suit against the Beast from Redmond.  Anyone who is running the Windows Operating System has Internet Explorer whether they want it or not — and you cannot get your Windows Updates without it.  So removing this very unstable browser from your OS is a very risky proposition and you just might have a high-tech doorstop on your hands…

So we recommend, as usual, only installing Security Updates and un-checking all other updates from Microsoft.  If you have Windows XP, stick with IE6, install Firefox 3.5, or even 3.0.1 — and Have a Nice Day.  Firefox 3.x gives you all the functionality of IE7 with a better interface and full access to all the tools and functionality you’ve come to know and love in IE7.

(08/21/09 Update:) On Windows XP, “upgrading” to IE8 (listed as a Critical Update by Microsoft) frequently results in a completely unbootable system. We had 3 of these in one week and the only solution was to reinstall the OS. On one machine, all the user profile folders had been relocated to the root directory. On another machine the drive was unreadable, requiring Data Recovery to retrieve their precious documents, email and photos. 

Do NOT install Internet Explorer 8! 

If you find you have Internet Exploder 8, give us a call…

Sysguard.exe Infection at Record Levels

July 16th, 2009

Over the last 2 weeks we’ve seen a dramatic rise in the infection rate from Sysguard.exe.  This infection masquerades as an Antivirus / System Security Center interface, reporting dozens of infections allegedly from an assortment of fake viruses, trojans and worms.  Whatever you do, DON’T give in to the threats and intimidation to pay them for protection.  The indicator you’re infected by this bug is twofold.

1: You will see a diagonally tiger-striped shield in your system tray.

2: Your Windows Desktop wallpaper will be replaced with a black or blue background with bright red lettering stating “Your’re” computer is infected.  Note the misspelling of “your”.

Don’t try to remove this infection.  It’s impossible for even most of the best computer techs.  We can do it, but it’s expensive.  We generally backup your data and restore your system, as it is less expensive and faster than “cleaning”.  All your system tools will be disabled.  You will not be able to edit your registry, manipulate the Windows startup applications or launch Task Manager when this pest strikes.

Please Stay Away if You’re Sick

April 30th, 2009

Nothing personal, but if you ignore the sign on our door and come in with symptoms that indicate you are sick, you will immediately be asked to leave.  

  • Our reception area will be sprayed with disinfectant as you leave.
  • Whatever you have, we don’t want it.  
  • If I get sick I will stay home until I feel better (and not contagious)
  • That means we will close our doors for the duration 
  • Our phones will not be answered.
  • Messages will not be returned.
  • You won’t get your computer back in any reasonable amount of time.
  • Neither will anyone else.
  • Be considerate and stay home if you are the least bit symptomatic.

Clever New Way to Hijack Your Computer – By Phone!

April 2nd, 2009

We were SO impressed when this story was relayed to us by a client today that I just had to pass it along.

A client of ours received a phone call from someone (ostensibly) in India yesterday who informed her that he had received a message from her computer, contacting his computer and he needed to gain access to her computer to stop it from contacting him – and could she grant him access to her computer.

She said, “well isn’t that interesting, since our computer isn’t even here. It’s in the shop for repairs right now.” At which point the caller hung up.

Isn’t this a clever way to gain control of your computer and steal your identity?  Just pick up the phone and play Dialing For Dollars.  Needless to say, you should NEVER grant anyone who calls you access to your computer.  Duh!

Conficker’s Gonna Gitcha!

March 31st, 2009

The biggest question of the hour is one or more of the following:

  • “OMG, is this Conficker thing for real?”
  • “What should I do to protect myself?”
  • “On April 1st is my computer going to be hosed?”

ad nauseum…

Since you apparently didn’t read my other TWO posts on this topic, read THIS ONE, OK?

Yes, variant C of the Conficker / Kido / Downadup worm is slated to take on a whole new characteristic on April Fools Day and, if you’re not properly protected, you will be in deep, deep donkey dung.

Clear enough?

If you had read my post on the Out-of-Band Windows Security Update last October (and installed it) you would already be protected and (hopefully) not pestering me about this issue.  Also, if you read my post from February 9th, when Downadup was first discovered, that pointed out exactly what I said in the previous sentence… Again… you would not be asking this question.

So to cover much of the same territory again…

On April 1st, this World Wide Pest is going to implement new insulation methods to protect itself.  Conficker C finds computers and network shares with weak passwords (or none at all), disables security services, antivirus protection, Windows Updates, and blocks access to websites run by legitimate security firms like Symantec and McAfee.  Smart as a whip, Downadup also spreads via removable devices, such as USB thumb drives or removable camera memory, using an infected Autorun file.  Conficker is wickedly clever and nothing if not tenacious.  It will attempt to “brute force” (guess) network Administrator passwords, so if you have some ridiculously easy password (like “password”) or no password at all… You guessed it – You’re SCREWED!

It is a very BAD idea to avail yourself of free website scans to detect this pest, as many of these so-called tools are a whole new breed of infection, taking advantage of all the hype to infect your computer.  There are legitimate free scanning tools from Microsoft, Symantec and McAfee, but if you have the appropriate current Windows security updates and our recommended AntiVirus (AVG) you should be immune to infection.

None of this is news.  We’ve been saying this Since early February. 
Follow these steps to protect yourself:

  • Manually check your Windows Updates and ONLY install Security Updates.
  • Do NOT install Service Pack 3!
  • Make sure your AntiVirus (AVG I hope) is fully functional, with no errors and has all current updates.  If the icon is the appropriate blue, red, green and yellow (and not gray), you’re OK.  If not, open AVG’s control panel and find out why – and fix it.
  • If your internet connection seems especially S-L-O-W – with no apparent event to trigger the slowdown, be suspicious and perform a full virus scan.  If you actually find anything, call us and let us clean up the mess.  Anything that slipped by is an indication of inferior protection or a VERY smart bug.  Neither is a good thing.
  • You can block the Autorun function of your Operating System.  Here are the instructions – but be very careful, as this modifies your registry.  One wrong keystroke and your computer no longer boots!
  • You DO have a current backup, right?

Recommended Laser / Inkjet Printers

March 23rd, 2009


Canon MF4690 Laser PrinterPeople routinely ask what printers we recommend.  We have exclusively recommended Canon and Xerox printers since 2007, when we felt HP’s quality and failure rates had slipped to unacceptable levels.  We have several Canon Lasers, one scanner and one inkjet, in addition to the collection of Canon cameras and lenses that Warren uses as a professional photographer. Across the board, Canon makes solid products and stands behind them.

The Black and White laser we use is the Canon MF4690.  We use them every day and they are workhorses.  It’s a fax, printer and scanner – we only needed the printer, but what the heck?

Our Color Laser is a Xerox 6180N. The price is right, it warms up and prints in under a minute and it completely network ready.  It’s a heck of a deal and produces spectacular color presentation quality pages at a very high rate of speed.

We have one of these in our guest room, plugged into the network.  I send a print job and by the time I walk over to the guest room, my document is coming out of the printer.  Can you beat that?

For those of you not ready to make the leap to a laser printer – or just need a small, energy efficient multifunction Printer / Fax / Copier / Scanner, we recently acquired a shiny new Canon MX310 which perfectly suits the bill.  It works perfectly on a PC or a Mac (our requirement at home) and is very quick, quiet and reliable. A relatively small footprint,  but packs a punch in a small package.
