FBI Gets Tough on Scareware

June 24th, 2011 by zam17 No comments »

The FBI is “taking off the gloves.”   The FBI’s attempt to smash  ’scareware’ comes at a time with significant up-ticks in cyber-crime taking place.  FBI’s “Operation Trident Tribunal”, in coordination with 12 nations, is an attempt to stem the growing “scareware” threat.

So whats the big deal?  The insidious nature of scareware is quite troubling.  Scareware works by pretending to be legitimate anti-virus software.  It will scan your computer and then say it can clean malware from it – for a price.  You do not get the option to simply say “not interested..”  The scareware essentially holds your computer hostage.

The FBI, on their website, estimates that almost a million people have been scammed by this software.   Most people who surf the Internet probably have seen phony anti-virus pop-ups at one time or another.  NEVER click on these.  Close them right away.   It might also be a good idea to run your own, legitimate, anti-virus software after such an event happens (If you have questions, just give us a call 972.781.0011).

Scareware is very difficult to remove from a computer. Often it will even cripple your own legitimate anti-virus software.  It can get so bad, that some uses simply end up reformatting their hard drive.  Scareware attacks literally cost millions of dollars in damages, stolen money, and lost productivity.  All while pretending to remove viruses that never existed in the first place.

The FBI’s investigation is ongoing.  To this point, there have only been two arrests, but things are about to get very interesting.

Scam Notice: New tactic of fraudsters calling you claiming to work for Microsoft!

June 23rd, 2011 by zam17 1 comment »

Police in Kitchener, Ontario have released a scam alert after getting numerous  complaints over the last few days about a computer virus scam.

Victims say they have gotten unsolicited calls from a person  claiming to work for Microsoft who offers to clean the computer of malware, viruses and other potential threats.  The end result is that the victim will be guided into downloading malware from the impersonator that can scan their machine for personal info, including banking information.

“People need to be cautious,” Waterloo Regional Police public affairs co-ordinator Olaf Heinzel said. “No matter what company a caller says they are from, the recipient has to make suitable efforts to make sure that caller is legitimate.”

“It only takes one or two victims to make this scam pay off,” Heinzel said.

Beware Firefox users! New Malware is targetting you!

June 16th, 2011 by zam17 No comments »

Yep, Firefox is the latest target in the ongoing Malware Wars!  Firefox users are the focus of a new scam that attempts to install dangerous and fake antivirus software by displaying a very passable Windows Update page.

Fake virus scams have been around a very long time.  What is strange about this latest version (credit Sophos with the discovery) is that it only becomes active to users on Windows and using Firefox.

The first big clue? Windows Update can only be started in the background in Windows or through Internet Explorer.The malicious popup that tries to get you to install malware is a copy of the Windows Update page offering an “urgent” 2.8MB download which will pretend to do a virus and malware scan, but really just install some of its own.  It is a pretty clevel job the creators did.  Click the image.

“Users need to be more vigilant than ever before as bogus security alerts pop-up in their browsers,” said Graham Cluley of Sophos. “Fake anti-virus attacks are big business for cybercriminals and they are investing time and effort into making them as convincing as possible.”

“Malicious hackers are using smart social engineering tricks more and more often, and the risk is that users will be scared by a phoney warning into handing over money to fix problems that never existed in the first place,” he said.

Attacking Firefox seems to be a bit in vogue, lately.  Last week, a separate scam that throws up fake security warnings in an effort to throw more fake/malicious software onto users.

Be on guard.

Keeping your Computer Fast!

June 6th, 2011 by zam17 No comments »

Even if you have a “bleeding edge” computer,  it is likely that is could run even faster.  No one likes a slow PC, but there are simple steps you can take on a weekly, or even monthly, basis  to ensure your machine is running at its best.  It helps to be a bit knowledgeable about computers, but you don’t need a degree in Computer Science to optimize your machine.

Get Rid Of Viruses, Spyware and other Infestations!

Spyware, trojans, worms, viruses and other forms of malware all play a big part  in keeping your machine from running quickly. Fortunately, there are a number of spyware removal and detection programs available both to purchase and to download free of charge.  Check out AVG, Avast, and Microsoft Security Essentials.  I recommend the latter.

Take The Trash Out!

Deleting a file or program doesn’t remove it form your computer.  It is then stored in the “Recycle Bin”.  This is a last chance stop for you to “undo” a deletion.  But this also means that the hard drive space isn’t reclaimed.  This can slow your computer down considerably.  Make it a habit to empty your Recycle Bin on a regular basis to free up space. Tip: Right click on the Recycle Bin and click “Empty…”

Stay up to Date!

Keep your machine up to date with the latest Service Packs.  Generally, your computer will notify you when there is a new update for your Operating system – DO NOT IGNORE THESE!  These updates often are meant to improve the performance and security of your PC.

There you have it.  A few simple things to keep your machine fast, and you didn’t even have to get a degree in Computer Science to do it!

How Does Windows 7 System Restore Work?

May 25th, 2011 by zam17 2 comments »

Windows 7 has a feature that enables the user to protect key systems files.  This feature has been part of windows operating systems since Windows ME, but has been refined for Windows 7.  One key improvement: You no longer are required to use 15% of your storage for restore.  You can use as little as 5%.  There are other improvements, but let’s take a look at how it System Restore works, in general.

What files does System Restore actually backup?

Firstly, System Restore does not backup everything, and it should never be used this way.  The primary purpose of System Restore is to ensure your computer can return to a normal working state, not to keep your personal data safe.

Files included:

Windows System Files – Certain .EXE and .DLL files important for the proper functioning of your computer.

User Profile Information – Certain user specific data that is important to the functioning of your computer

The Registry – The registry is backed up, but this alone doesn’t mean that all of your programs that depend on the registry will continue to work properly.

Some examples of files that won’t be backed are your personal photos,  movies, music, etc.

Also, email, documents, and individual program settings which are not stored in the registry, will not be backed up.

System restore points can be created manually, or at times specified by you.  Keep in mind, however, that Windows has what are called “application hooks”.  These are pieces of computer code that allows others to develop software that manipulates the Windows OS.  One such manipulation is being able to force a restore point when a program gets installed.  This can provide a little protection in case the program causes damage to your machine.

Laptop Maintenance, Easy Tips

May 13th, 2011 by zam17 No comments »

For most people, a laptop is a big investment.  By following a few simple steps you can keep your machine out of a laptop repair shop, and in good, working shape for a longer period.  In order to keep it out of the computer repair shop, you need to keep a few things in mind.

To begin with, avoid putting your laptop through temperature variations.  Also, it should not be in any place where it is likely to encounter lots of dust.  Not doing this can increase the odds of malfunction and data loss.

Avoid intense heat.  When outside, try to avoid keeping your laptop in direct sunlight for any long period of time.

Despite the name, avoid putting the laptop on your lap.  This can block airflow to critical internal components, causing potential overheating.

Treat your laptop like the fragile item that it is.  Do not man-handle it. Because you _can_ eventually damage things by not using proper care when picking it up, setting it down, and opening up the top when you are about to use it.

Since laptops are mobile, it is very easy for foreign materials to get inside the keyboard, vents, ports and other openings.  Be diligent in protecting these areas.  Avoid eating and drinking near your laptop.

Give us a call for more tips and metallic laptop cases.

Mobile Threats Double in Number

April 21st, 2011 by zam17 No comments »

According to Kaspersky Labs (www.kaspersky.com) the number of malicious software programs focusing on mobile devices more than doubles between August 2009 and December 2010.  Some of these new threats are for the new “Android” platform, with 15 total programs targeting it.

The most common tactic that targets mobile devices is to use SMS Trojans.  By enabling SMS messages to be sent without the user’s consent, evil-doers have direct access to their funds.

Keeping Your Computer Fast, Part 2: Tuning Your PC

February 28th, 2011 by zam17 No comments »

In the last article we discussed how keeping your PC free of viruses can aid in keeping your computer fast.  These week we shall be discussing various methods of tuning your machine in order to keep it running optimally.

Defragmentation

One important maintenance task that needs to occasionally be done is to defragement your hard drive.  Over time, files, and data on your computer, though part of the same file, get separated into different physical locations on your computer’s hard drive.  This slows the operation of your computer by increasing the time it takes to access a file, in its entirety, from the hard drive.  If the majority of your disk is not fragmented, the overall operational speed of your machine will increase.

Registry Cleanup

The Windows Registry is a part of your Windows operating system used to store data that might be needed later, either the operating system itself, or various software installed on your machine.  As time goes on, the registry may get out of sync  with  your comptur and contain invalid information.  This can cause operations to be taken that are no longer necessary thus slowing down your computer.

These are just two really important maintenance tasks that can be used to tune your computer and keep it fast.
