Hi, thanks for taking your time to help me and others on this forum! My computer got hit with a variety of Sirefef infections - AB, AG, AN, AO, and AZ, looking from the Microsoft Security Essentials history. MSE also found JS/Redirector.HQ and JS/Obfuscator.CA, and I'm not sure if there's anything else. It started when Adobe Flash tried to update on its own, and all of the security services were disabled subsequently. Firewall and MSE did not work, so I tried reinstalling MSE, and when that finished, the computer warned me that it would restart in a minute. Ever since then, I haven't been able to use my computer without it restarting within a minute of booting up. I can't boot to Safe Mode without it restarting, either. Right now, I'm backing up my files by booting Ubuntu and saving it to an external drive. Again, I appreciate your help and hope to get my computer back and running!
