Virus symptoms under XP Pro upgraded to SP2, 2.6 Ghz Celeron, 512 MB, 96 GB free is, is 100% of CPU is in use per Windows Task Manager (WTM). So Macafee won't run at reboot with error that it cannot get enough resources to run. System Restore will not run giving empty white window. System Information starts but then says it cannot give any statistics. PC operation is generally very slow but internet access via IE browser is possible. Results in Safe Mode with Networking are the same, no better.
WTM, process tab, shows svchost.exe is the culprit and one instance of it has about 50% of the CPU and the System Idle process has the other 50%. There are also other instances of svchost.exe that have 0% cpu usage. But these are averages, the CPU usage graph shows big fluctuations. I assume that this lack of CPU resources is what the Macafee error message is referring to and is the reason System Restore and System Information (effectively) will not run. WHY IS THIS IMPORTANT. Because if I could get the CPU back I could system restore to the day before the problem began which is a known date and all would be well again. Or I could run a virus full system scan in Macafee or Norton or some other virus remover especially good at removing the Welcha virus.
Why do I think this is the Welcha virus. Go to http://forum.pcvsconsole.com/viewthread.php?tid=8191
and scan down to the 3rd post by Trunks007. A complete match to my symptoms plus if you read the first few pages of this thread others confirm this. The initial post in this thread is for Windows 2000 Pro but if you read on you see this post expands quickly to include XP too.
Well if I have read this non-EE thread WHY AM I POSTING HERE ??
The reason is that the thread consists of, problem, then solution, then "I tried that and it failed", then, "no try my solution" and again (from a new person) "no, I tried that one too and it failed" and so on.
Hence my request here is provide a STEP BY STEP detailed procedure to get rid of the Welcha virus under XP Pro that WORKS. Don't skip a step because you assume any security expert would know to do that. I am not a security expert. Also be aware that if Macafee won't run (it starts but then we get the error message and the Macafee icon in the lower right taskbar turns from red to black) that other programs may not run too. So if you tell me to do a Norton AV full system scan, well that may or may not run too. I don't know for sure. Also doing things in Safe mode does not solve the CPU usage problem here because svchost.exe is on the short list of processes that are allowed in Safe mode so the CPU usage is 100% there too. Very inconvenient isn't it.
Now for one ray of hope. From the various posts at http://forum.pcvsconsole.com/viewthread.php?tid=8191
, I see some posters think that his whole thing only happens if the PC has internet access. And I'm not 100% sure that my claims of 100% CPU usage were with Safe Mode vs Safe Mode with Networking. I think I saw that System Restore would not come up in Safe Mode but it may have been Safe Mode with networking.
Please note I am NOT asking for information on the Welcha virus or on svchost.exe, I am asking for one thing only. A step by step instruction set for removing it under Windows XP Pro that works. If you can not provide that or a link to such a step by step set, then do NOT respond to this question.
