Everything started with a fake anti-virus pop up on my toolbar. It warned me of infection and prompted me to do a system scan. I attempted to start my task manager to kill the process, but an error message popped up claiming that my task manager .exe was infected, thus disallowing me to execute it (this persisted with every other program I attempted to open, rendering my computer useless). It also caused internet explorer to pop up annoying viagra ads which I couldn't shut down. I immediately rebooted my computer. I opened my task manager upon restarting and killed the program immediately which allowed me to perform a few virus scans with superanti-spyware... This resulted in Trojan.Agent/Gen-Rogue, Trojan.Agent/Gen-Krpytik, Rogue.AdwarePro, and Rogue.AntivirusSoft. I scanned a second time with the results: Rogue.AntivirusSoft and Trojan.Agent/Gen-Rogue[Installer]. Even after completing the second scan and rebooting my system, the annoying fake anti-virus software assaulted my desktop. A scan from microsoft security essentials yielded nothing, and so I came here and embarked upon the 8 steps. I downloaded Avira and it found Java/Classload.IB.2 Java Virus and Java/Classload.IC.1 Java Virus, which were quarantined. After scanning with Mbam it appeared as if my computer returned to normalcy, however I'd like to be 100% certain. Logs are attached sans Gmer, as it found nothing and the .log is completely blank.
