My web browsers are acting weird?

[マシュマãƒ]

Well, there is two problems I've notice that are quite annoying.
First, I have McAfee SiteAdvisor and every time I run my mouse over the bar at the bottom it freezes my Firefox. I tested it on Internet Explorer and it also does it on that one too.
Second, when i search something (Google, Live, Yahoo!, etc.) it freezes if i click on a link.

Any idea of what the hell is going on? I use google all the time and now it doesn't work worth crap.

I've checked for viruses, re-installed my Firefox, etc.

Everything besides that is running good.

I've also tried using my Firefox in Firefox's safe-mode and, of course, it does the same.

I cannot reinstall my operating system cause i have WAY to much crap on this computer and i don't have anything that would possibly hold all of it and right now, with Christmas, moving, divorce, and other crap going on around here, i cannot afford one.

(Sorry if i sounded irritated on the above sentence, I'm not)


P.S. I've got Windows Vista Home Premium. (If you need to know.)

Any further information you need about my laptop (if any) you can just ask.
It removes it in safe mode, so that isn't the problem.

Try to remove McAfee SiteAdvisor.
