the hijack this log looks good except for a couple entries,
do you know what this is?
O4 - HKLM\..\Run: [tgcmd] C:\Program Files\Support.com\bin\tgcmd.exe /server /startmonitor /deaf

Some file discription DB's have it listed as belonging to a support services for a 3rd party MFG device so it is probably OK

We are pretty much all asleep right now, but I'll let Shadowputerdude look at the rest of the info, Judy is on vacation for the weekend and I'm not well versed in xp, so I can't help much on the system32 folder issue.
