Hello, I just registered and am forced to write this on my small netbook, I would be really grateful for any help. I will try to be as detailed as possible: My computer runs Vista 32-bit with Microsoft Security Essentials, I have everything up to date. I am not sure if it is important but my OS language is German and my system locale is set to Japanese. I recently had a couple of tabs open in IE when a prompt for a flash player updated came up. This was strange since this normally only happens right after the computer booted and not while surfing. I very stupidly gave the UAC permission to update and for the rest of that session nothing happened. After starting the computer the next time, MSE was disabled and couldn't be reactivated and I also found a new process running called 0i763f66bz.exe. I panicked and un- and reinstalled MSE, which then ran and found two sirefef alerts (virus+trojan) after trying to remove the threat the system started to give a warning that it reboots in one minute, which it does non-stop since then. Because of that I can't follow the 5 preliminary removal instructions. I really appreciate this site and any help that can be given, thanks.
