Try using an older version of HijackThis:
Please download
HijackThis - this program will help us determine if there are any spyware/malware on your computer. Create a folder at C:\HJT and move HijackThis1982.exe there. Run a scan and save the log file. Get
HijackThis Analyzer and save it to the same folder as the hijackthis.log file. Run HijackThis Analyzer and type in y if you agree. Open up the
result.txt file created. Copy the whole result.txt log and post it in the forum. Do not fix anything in HijackThis since they may be harmless.
I don't think IE-Spyad or SpywareGuard should have affected anything here. I suggest installing them back.
