Can't Access Firefox or Chrome

So I had some malware problems that messed with my internet and laptop. Went over to the Spybot forums for help and it seems to have cleared up, but I'm still experiencing symptoms that I had, which is lag and not responding problems. Another one of the main problems is that I can't open Firefox or Chrome. I can use Opera and Internet Explorer.

When I first boot up and open Opera, it will lag and not respond for about 30 minutes and then act normal. When I try to open Firefox it tells me that it is already running, but is not responding. Chrome doesn't open at all. Not only does it not open, but it also affects Opera and Internet Explorer by making them, and my computer in general, lag and not respond every 10 seconds, making it irritating and almost impossible to use. I posted in another section about possibly doing a repair install, unless somebody has another idea. On a side note, I can't open iTunes either.
