Ways to prevent 70% virus, malware attacks in your PC

Saturday, January 26, 2008

Most viruses, spy wares, malware use certain well known patterns to enter your PC. This articles describes how to stop all the common ways in which viruses enter your PC running Windows XP.

These solutions are extremely handy, if you don't have/like to install Anti-Virus software like me :)

TURN OFF DRIVE AUTO RUNS

Most Viruses run only when the user double clicks the USB pen drives icon in My Computer. There is an easy way to stop this.
  • - Go to Start Menu > Run (Windows + R)
  • - Type gpedit.msc
  • - Go to User Config> Admin Templates> System.
  • - On the right side double click Turn off Auto play
  • - Change Value to Enabled and make it on 'All Drives' in the combo box below
  • - Repeat the above steps for Turn off Auto play option in Computer config> Admin Templates> System
SET SOFTWARE RESTRICTION POLICIES
  • - In the same group policy editor windows Goto Computer config> Windows Settings> Security Settings
  • - Right Click Software Restriction Policy and give create new policies. If that option is not present then just expand the tree below.
  • - Click on Additional Rules and on the right side Right click on empty space.
  • - Select "New Path Rule"
  • - Enter the Drive Letter for your USB Drive and set the level as Disallowed and Apply.
  • - Now all executable files present on that Drive Letter are blocked (all .exe, .bat, .com etc). Thus when virus is present in the disguise of a folder icon, even when u double click it wont run.
Downside of this method :- When you need to run an application from the USB Drive you need to copy to your system's local disk and then run it. But I have found this approach very good to prevent viruses. You can also use this method to block EXE running from other drives as well when you have all programs installed on your C: or D: Drive.

BLOCK INTERNET EXPLORER 6 - USE FIREFOX

Internet Explorer 6 is one of the browsers with a lot of security holes and vulnerability issues.
  • - Go to C:\Program Files\Internet Explorer.
  • - Right click iexplore.exe and rename it to something else. Or go to Properties > SecurityTab and remove all entries from there. If the security tab is not visible go to Folder Options > View > Scroll down and uncheck "Use simple file sharing".
If you have not done it yet, download Firefox - the best browser in the world and try it today. Its got millions of cool add ons that will make you love it.

NEVER DOWNLOAD TOOL BARS

Never download any tool bar from any site. Even if they claim it to be 100% spam free except from Stumble Upon :P , (Google, Yahoo etc. optional). Even if its very very essential please Google it once before installing.

UPDATE YOUR BROWSER REGULARLY

Most Viruses from internet use the vulnerability in your Browser to download themselves. So please keep your browser updated everyday with latest patches.

    In windows xp these work fine.. Probably in Windows 7 or Vista, I have not tested. But you could search for Group policy editor in google along with your windows version. OR just comment the windows version here and I would like to help you out
