I'm having a problem with a friends computer. He recently ran a avast boot scan in which on prompting him what to do with viruses he said delete all.
Here's the problem, some of the viruses were in the System volume information folder which got corrupted (I'm pretty sure). So now on his computer (XP) he has a 200 Gb capacity drive with 70 Gb's worth of stuff on it but with only 50 Gb's free space. Some how 80Gb's are being mislabelled or whatever. I've tried using partion magic , chkdsk command, Disk management, cleaning out all temp folders etc. Nothing worked. All diagnostic tools simply say that the 80Gb's is being used when it's not. Is there a tool to refresh the System Volume information folder or do I have to reformat the hard drive(I hope not).
Any help appreciated.

The 'system volume information' folder is where Windows XP stores the restore points for when you need to use system restore. As it also stores viruses which may have been acquired, and since no antivirus product is able to rid this folder of viruses, you should always delete ALL restore points which will also delete any viruses within them.

To delete all restore points:
1. Control Panel - change to 'Classic' view.
2. Click 'System' then click the 'System Restore' tab.
3. Tick the "Turn off system restore" check-box and click 'Apply'
4. Wait a few seconds then remove the tick, click "Apply" again.

Job done

Before clicking "OK" to close the box, take note of the slider. This shows how much of your disk space is reserved for restore points. This amount of space will always be unavailable for anything else, even when the data within it is much less, because Windows has reserved it solely for the purpose of storing restore data. If you want to lower the amount of space it uses for that, do it now by adjusting the slider. Doing so will release more space for programs and your own data. Then click 'OK'. Just bear in mind that less space for restore points means fewer restore points will be available to you when you need to use System Restore.

Thanks but I guess this wasn't my problem. I still seem to be missing quite a bit of space. Any other ideas?

Check for file system errors and bad sectors on your hard disk.

Double-click My Computer, and then right-click the local disk that you want to check. Click Properties, and then click Tools. Under Error-checking, click Check Now. Under Check disk options, select the Scan for and attempt recovery of bad sectors check box. Click Start.
