This is a very bad idea!!!

Programs like RegCure cause more problems than they solve. If you search
the archives of this newsgroup, you will see many examples.

Was that the only time you ran RegCure? Or did you ever run it before
this svchost.exe problem began?

I used to run AVG 8.5 Free and was very happy with it (the minimum
configuration, too). However, now that I've test-driven 9.0, I avoid it
like the plague because of its horrible resource hogging.

Actually, I never ran the "Internet Security" suite. Suites, as a rule,
are problematic and can cause conflicts with other programs. You might
want to consider configuring a Clean Boot to see if AVG is causing you
problems:

I ran a Google search and learned that others with your particular
symptoms had malware. Example:

This is indicative of another process or processes being launched by
svchost so my guess is you have gobs of stuff running in the
background. Go and grab Process Explorer (free) and fire it up. It
will show you what sub-processes are being launched under svchost.exe
and then you can see very clearly the offending CPU hog. Post back
with your findings.

You could try the following hotfix :
http://support.microsoft.com/kb/897571
Don't be fooled by the date, the hotfix will install svchost.exe
version 5.1.2600.5689 which is newer than what is in SP3.

> I installed RegCure...

If you ever think your Registry needs to be cleaned, repaired, boosted,
tuned-up, or optimized (it doesn't), read
http://aumha.net/viewtopic.php?t=28099 and draw your own conclusions.

Seldom? Well, I think you've got another one now...

NB: If you had no anti-virus application installed or the subscription had
expired *when the machine first got infected* and/or your subscription has
since expired and/or the machine's not been kept fully-patched at Windows
Update, don't waste your time with any of the below: Format & reinstall
Windows. A Repair Install will NOT help!

1. See if you can download/run the MSRT manually:

NB: Run the FULL scan, not the QUICK scan! You may need to download the
MSRT on a non-infected machine, then transfer MRT.EXE to the infected
machine and rename it to SCAN.EXE before running it.

2b. Vista or Win7=> Run this scan instead:

3. Now run a thorough check for hijackware, including posting requested logs
