Download CleanUp!
http://cleanup.stevengould.org/ (Alternate Link if main link don't work -
http://www.greyknight17.com/spy/CleanUp.exe ) and install it. CleanUp! deletes EVERYTHING out of your temp/temporary folders, it does not make backups. If you have any documents or programs that are saved in any Temporary Folders, please make a backup of these before running CleanUp!. Run CleanUp! and click on the Options button. Uncheck 'Scan local drives for temporary files'. Also uncheck those two Newsgroup entries if you don't want to delete them. Click OK and then click on the CleanUp! button. Let it run. After it's done, choose Yes to logoff.
It doesn't look like you have any viruses or spyware. I would try uninstalling the program then reinstalling it.
