...now my pc isn't function rite? Ok, so i saw these weird pop-ups in my toolbar on the right hand bottom corner which said stuff like,"You have a virus/ trojan and other crap.Also it ran these fake scans of the computer and then tried to urge me to buy its fake product. I knew it was a fake so i didn't mess w/ it and ran superantispyware. Once i ran it it found Trojan.RogueAV so i continued and it removed. After that it rebooted my computer and now almost nothing seems to work. Whenever i click on any icon, whether on the desktop or in the start panel it comes up with a screen saying, "Open With", and gives me a list of programs. I cannot open internet explorer, mozilla firefox, or almost anything else. Sometimes it doesn't even come up with "Open With" and just says error. Even the start menu doesn't open up. Also a random program keeps poping up called Just-In-Time debugging. I looked up the virus but found almost nothing on it and im so tired of this stuff. Also running regular .exe files doesn't work and random pop-ups in my browser keep coming up and trying to attack my PC again. Please help, i can't afford to fix it or buy another.
