I just stumbled across your forum looking for an answer to my question. I found a similar one, but the instructions were very specific.
I just got a new job and the computer they have me using is complete crap. The guy before me really got it messed up. Now every time I'm on Mozilla, about every 3-5 minutes (sometimes more) a new tab will open up followed shortly by a IE window opening up. I have McAfee secuirty suite, which sometimes blocks the site which is trying to open up but it has done nothing to stop the actual window from opening. I was hoping that someone here may know what to do.
I downloaded HijackThis, because that was what the person with a similar question was told to do. I will post the results of my scan in my next post in case this will help speed things up a bit. Thanks in advance for any help.
