I had two anti-virus programs installed and my friend recommended that I remove one of them. I had Norton 360 and McAfee. So, I removed McAfee and my computer started behaving weirdly. I couldn't access specific folders, especially the windows file folder, it kept on crashing.

Google Chrome, iTunes and Adobe Reader all stopped working. They won't even open. I just installed Firefox and Foxit for time being, but that doesn't solve the problem.

I showed the laptop to a technician and he said that my hard drive might be corrupted. But it's been only 8 months or so. I didn't start experiencing these problems until I un-installed one of the anti-virus programs.

Can my hard drive be failing or is the problems I am facing due to the un-installation of the anti-virus?

The first thing to do is to check that the Windows installation and drive isn't corrupted in any way as a result of the uninstallation. You can do this by running a disk check. See this link on how to do this: windows.microsoft.com/en-us/windows-vista/… Make sure you check the option 'automatically fix file system errors'. –  Oliver G May 3 '12 at 11:10
    
thanks Oliver.. I guess the technician already checked for that..and he didn't found anything..he then mentioned something about the lens of the hard drive is not working properly and that the whole hard drive might have to be removed!! :( –  Nikunj May 3 '12 at 11:45
    
If that is the case then yes, it would require replacing the entire drive. I find it a little suspicious though that it coincided with you uninstalling the secondary AV program - especially as AV programs have a tendency to bury themselves in the system. –  Oliver G May 3 '12 at 11:57
    
i think dat too...bcoz i never had any problems before uninstalling the AV..so shall i uninstall Norton as well and install MSE and check for viruses???? what abt the case of unstable shell extensions and checking them using Autorun s/w?? –  Nikunj May 3 '12 at 12:02
    
Remove all AntiVirus tools, then run a full surface scan. Use the McAfee and Norton removal tools from their respective websites, not the uninstaller in Control Panel. –  user3463 May 3 '12 at 15:38
