Here's what happened before this; Periodically, my browser would not use the avg search. It goes to "not responding". If I use google, then I get redirected (from anything I select) to gimmeanswers.org. I figured I had a BHO hijacker and virus, so I ran Norton Internet Security and found nothing. I then searched for BHO removals and found Hitman Pro, used it and found a trojan and removed it. Here's what's happening NOW; I thought everything was fine, but then as I was surfing, I got a hit from Microsoft Security Essentials on a trojan just as a Flash installer popped up. I already have flash, so I thought "wtf" and put 2 and 2 together and said "I'm still infected.". Now running Norton, MSE, or HitmanPro I found nothing. I used to have Malware Bytes on my machine, but it kept missing stuff so I removed it. I have been running SuperAntiSpyware, MSE, Norton IS 2012, and Spy Bot. I know a lot of people say to stick to one thing, but honestly I have never found ONE program to protect my system. The claims that they interfere with each other may be legit, but by utilizing so many programs I have managed to find things that have been missed by the other software. And since I have a home network (through our Uverse modem), I worry about infection from my nephew's computer as he surf's anime and porn all day long with no caution at all at how he can infect the network. I don't think a virus can infect my wife's e-reader, but I don't want to take chances. So with all that said, how do I determine if I am clean or not? I am disabled and work from home using this PC, so it's imperative that I keep it secure and clean. I appreciate any help you guys can give. Thank you.
