My workstation got hit with the XP Defender virus on Monday April 5, 2010.
This wreaked some major havoc on my machine. It took the IT guiy over a week
to clear out all traces of the virus. In the meantime, some system files
(among other things) had gotten corrupted. IT replaces these files with
files from another machine - probably older files. We then ran windows
updates but encountered a problem with the silverlight update. Also, Visual
Studio 2003, 2005, 2008 SP1 loaded on this machine. VS2008 SP1 also
complained about sliverlight - actually about the xaml. We tried removing
sliverlight so we could reinstall it but kept getting this dialog box saying
that the installed product didn't match the installation source. I also
encountered this problem with Quictime (which isn't even microsoft). I can't
remove quicktime from this computer either, and I can't reinstall it.

Is there a fix for this? Or is this a reformat thing?

Thanks

"XP Defender" is not and was never a "virus". It is malware but not a virus.

All viruses are malware but not all malware are viruses.

Are any of the drive letters on your current machine different from that of
the source of that registry file?
