my brother in law was on my computer (bullshit ass myspace) and when I got back on, I noticed the background on my desktop was showing a big red box with a "Warning you have been infected" . Well I was able to get rid of that, but now I am hearing this beeping sound, almost sounds like a pop-up blocker, and everytime I do a search on google some weird search engine is coming up. (not to mention firefox crashes all the time now.) I was running mcaffee but switched to AVG and installed malware Bytes. Any ideas on what I can do to get rid of this crap? Should I do a hijackthis, and if so where do I submit the logs to?
