According to my AVG Scanner, my computer seems to have been infected by a .shs virus. I've located it in a file that came with a printer driver download. It seems to be doing no harm, should I ignore it or start tinkering in the Registry ?
can be used as a trojan within Windows. The extension is actually what is called a Windows Shell Scrap Object. The most famous (or infamous) example of this type of infection is called the 'Stages of life' virus because it came disguised as an attachment with jokes about the stages of life.
You can safely delete the file involved, but don't go tinkering in the registry yet.
Took the Forum Editor's advice and deleted the files concerned. A further AVG scan reports no infections now - so I guess the problem must be solved (unless my printer expires because a piece of its driver has been chucked away).
