Because of the way that operating systems access files, only one program can access a file at once. If a file is being used by another program, or is a system file that is constantly used whilst the operating system is running then the virus scanner can't access it to fix it.

A boot time scan is a virus scan that is run before the operating system fully loads up. This means that the virus scanner can have access to all the files on the computer with no chance that they're being used by another program or the operating system.

This means it is much more likely to find and fix viruses that have affected critical system files, like the contents of the c:\windows folder on the windows operating system.

In order to protect your computer from the newest virus should you do after you've installed virus scan software?

After a first-time install... Re-boot your computer into 'safe' mode. That stops most programs running - and loads just the minimum drivers to make the computer usable. Run an update of the anti-virus program -to download the latest virus definitions. Run a FULL scan with your anti-virus program - which will check almost every part of the hard-drive. Assuming the program has the option - run a 'boot-time' scan - which will analyse parts inaccessible under normal operations. Once you've run a full scan, and presumably the program has returned no virus detection - re-boot your computer in 'normal' mode - and you're all set

I have 360 Gb hard disk i cant open the disk any computer and If i am going to do scan with AVAST anti virues there is no progress. kindly suggest me what i want to do...?

There is a boot time scan in Avast antivirus. Schedule the boot time scan and restart the PC Avast will try to fix the virus problems before the user authentication window. Note: Make sure that you should not delete the system files when Avast scanner has detected the system files as corrupted. Like explorer.exe , svchost.exe etc. If this has not fixed the problem, then download a live cd for windows and boot from it. Backup all the data and reinstall the windows.
