My (other) pc was hit with a virus which although I can boot, I can't do anything at all with any programmes. Does this mean a complete 'restore'. There are things which I never saved and will obviously lose if this is the case.
Try running the avast virus cleaner click here a small download, easy to put on a floppy disk, with notes on how to run it if your .exe association is corrupt in the paragraph headed 'Solving other problems' at the bottom of the page.
Thanks Swampy, I will try that, anything in fact. I got into safe mode as Gandalf suggested and could only use the tab key which was very limited. If I did get into a prog it was with limitations. I will try Belatucadrus's prog also which I put on disc. I know this thing is in the 'help' files as the anti-virus showed me the address but said it could nothing.
