Malware opening random internet links & slowing computer

gmn819,
Let's check whether you have any other leftover infected files or settings.
This scan can take a long time (hours), but it is very thorough. Please start it when you can let it finish.
It doesn't remove anything. The report, however, is very valuable.

Ok I'll remove irc, though I have had the program for years without any problems, I guess it must've got infected..

Older versions of programs like Mirc have been used for a long time by spyware purveyors.
They try to exploit whatever defects or openings they can find in older software.

For a similar reason, it's important to remove old versions of Java and Adobe reader.
