Hello to all! I have a laptop here running on windows 7 64 bit, and unfortunately it got infected with sirefef.y. When I understood what the problem was (since it was infected by an inexperienced user -> not me ), I uninstalled ms security essentials and reinstalled it. The problem however was to reboot after a 60 second warning. Actions I have taken so far in order. Ran kaspersky rescue disk and avira rescue disk with no result. Booted into windows 7 and uninstalled mse in order not to reboot in 60 seconds. (successfully. I can now stay logged in in windows enviroment, but no firewall or antivirus is running) Run a Malwarebytes' Anti-Malware test with the results attached. Deleted all temporary data at Windows\temp folder and user folder. Read this post here https://www.techspot.com/community/topics/sirefef-removal-60-seconds-reboot.181609/ and ran an FRST with attached result. However as I read here, manual solution is the only way. So please help me out guys! Thanks in advance.
