So for the past 2-3 weeks, when i open up any internet browser, i get random pop-ups that i have never gotten before (internet surveys for wikipedia and facebook, and random program download links). So I called my older brother who is really good with computers and he said that my computer has been infected with a virus that one of the anti-virus companies made so that i would have to buy their product. He told me that he would fix it when he got back home (he's out of state for college and wont be back for another month). After that I just dealt with the pop-ups and always Xed out of them. But today when i turned on my computer (which is now on max security with zone alarm anti-virus stuff) and i got more security alerts than i normally do (6 instead of the usual 1) and i didnt think anything of it until i got back from church and noticed that a new program was installed on my computer called pc defender. My computer also would not play my Call of Duty (which now works), but when i go to use ctrl alt delete to see what was going on, it says that it (the task manager) is disabled by the administrator. And now whenever i start a program (my games or internet) it opens up a list asking me what i want to open this program with. I've tried using mbam, but apparently this virus blocks that too because it says it cant find the .exe file thing. So is there any way to fix this problem? I'm worried that my computer might get really messed up from this thing.
