Helping people with computers... one answer at a time.

Svchost.exe is a Windows component that often shows up in error messages. Unfortunately, quite often when it does the news isn't good.

svchost.exe error: svchost.exe has generated an error - now what do I do?

One of the most common search terms that leads people to Ask Leo! lately is "svchost" or "svchost.exe". Besides wondering what svchost is, which I discuss in this prior article, many people are experiencing a svchost crash.

Folks, you probably have a virus.

The svchost.exe error can result when your machine is infected with any of a number of viruses and worms. A quick search at the Symantec security reference site turned up no less than 53 references with some of the current top threats showing svchost symptoms.

So step one should be to make absolutely positive that you are running an anti-virus checking program and that the virus information it has is up to date. Depending on the specific virus you have there may be a removal tool available separately that will fix this one problem and allow you to continue with your upgrade (specifically, the blaster virus seems to be quite prevalent, and Symantec has a removal tool for it here).

Step one-and-a-half (it's actually equally important as step one) is to make sure your operating system has all of the latest patches applied from Windows Update. These viruses exploit vulnerabilities in the operating system that were patched months ago, so if you got infected then you're not up-to-date.

And finally, for a somewhat long, occasionally technical but very informative thread on this issue visit this discussion out at Experts Exchange.

what is this is this C:\Windows\bvtn.tmp\svchost.exe

In that folder it's likely malware of some sort. Run up to date scans asap.

I had the same problem on a new slave HD I installed. I simply did a clean install of XP which eliminated the problem. All other fixes I tried just didn't work. All my files (music and pictures) were retained with the new install. Hope this helps.
