Thanks for the helpful replies, folks. After spending the better part of this morning going through my windows files, I found a little exe called, isInstall. When I tried to scan it with Norton, it crashed windows. Upon restarting, I get a popup warning me that a "malicious script was detected and removed". The trojan was, isInstall.exe

So I did a full system scan again, and Norton didn't hang-up in the intuit\shared file any longer. Windows also shuts down and restarts normally. :cheesy:

I hate to post another thread in the security forum, so maybe a moderator could move this? I ran HighJack, and this is my log;

The 04 HKLM lines in bold I find suspicious, but I really have no idea what I'm looking at. Are these actual problems?

Again, thanks for the help.

Close all (browser) windows & rescan with hijackthis. When the scan is finished place a check in the box to the left of the following entries & click 'fix checked':
