Someone correct me if I'm wrong, but it shouldn't matter what SP you have, because if you repair your installation when your computer is back connected to the internet, it will just update the files again.

Boot to your XP CD and press 'R' when you get to the menu. Select the drive you want to repair and if you don't have a password on your hard drive just press enter when it asks. Type 'chkdsk /r' without the ' ' and press enter. Run this process until it doesn't find and fix any errors. (This process can take some time)

You can also try this:

Open My Computer, right click on the C: drive, click Properties, click the Tools tab, then under Error Checking, click Check Now...

Reboot & let it do it's thing.

Type the following in the Run box, hit Enter key and it will check your system files and replace any that are incorrect or missing:
sfc /scannow

(just the one space after sfc).

It will probably take about 15 mins to run through.

Always pop back and let us know the outcome - thanks

I've never seen an anti virus program that scans for corrupted files. Are you sure it didn't show you quarantined or infected files?
