I would get rid of this ones:

O4 - Startup: LimeWire On Startup.lnk = C:\Program Files\LimeWire\LimeWire.exe
O4 - Startup: PowerReg Scheduler V3.exe

However I don't think they caused the problem. Try the following command:regsvr32 urlmon.dll

Also you can visit the following article: http://oehelp.com/ielnk.aspx
It's not exactly related but it touches the same issue with different symptoms.

That log does not look comlete, it is missing the header...

Download hijackThis. Extract it to its own folder. Then run it and select. Do system scan and save log. Post the contents of the log that pops up.

We will then go from there...

This should also be moved to the virus/spyware section...thats where the logs go

I did that and displayed it above. Please help?

I am sorry to say this, but it needs to be done. HJT is running from a temporary folder, it is best to let it run from its own folder, as it allows it to create back-ups among other things.

Please download the self installing version here: http://downloads.malwareteks.com/HijackThis_1991.exe

Then please post a new log

And yes you did post a log above, but, it was missing a few parts...

I also saw there STOPZilla which is a pop-up blocker. Maybe it's not functioning properly and that is why you can't open links

Try to uninstall it and see if that changes anything.

One more thing. I strongly advise you to use Firefox instead of Internet Explorer it's much more secure.

Download and run the free IEFix utility.
