If you're familiar with this windows error (svchost.exe) please notify me with a solution to the problem.
What exactly is the error? Have a search on your drive as it should only be in your system32 folder. If its elsewhere it could be a virus.
What it caused. Is it allow to open drives by double-clicking? If so it's a script. Actually not harmful for the applications setup on your machine.
The file may be corrupted. I had the same problem before and there is a virus that hides itself with the same name, but sometimes its just a file corruption and not this virus the cause. Fortunately, I solve my problem just repairing XP. So, this could be an step .
