Very odd problem

[TurcoLoco]

I edited the screenshot to show only the entries that I found suspicious but of course they may not be malware related, it is hard to tell by looking at a screenshot, I often need to dig further into the registry to confirm and take action so I suggest you use another Rootkit scanner such as the one Jholland suggested, a few other programs I'd like you to try using and saving the log files of the ones I mention:

RootKit Hook Analyzer
SS-Keylogger Clean

You won't really need a log file saved for the above two, just download and run them.
Rootkit Hook Analyzer in Safe Mode and the KeyLogger in the Normal mode. When running a KeyLog Scanner, I often run a browser and write and e-mail etc. to mimic keyboard typing to provoke to a dormant keylogger that may otherwise be missed by the scanner.

Last but not least, I would like you to d/l and run a scan with Autoruns, then save a log file (not a screenshot please) following the instructions on this post. The post has the download link as well.

After running all your mentioned programs...

The AVG Anti-Rootkit detected nothing.

The RootKit Hook Analyzer detected 15 hooks. I apologize once again for having to save the log as a screenshot, because I was unable to save it as a .txt or .log file for some reason.

The SS-Keylogger clean detected nothing.

I was able to save the Autoruns log file as a .txt file, so that's included in the attachments.

Thanks, I appreciate all your help so far.

Did you do a search for that "not valid any more" LSP 25,5g entry as ~TL suggested? Have never seen anything like that before, you really need to do the search as requested in post #5 and give us the results of that.
