Hello everyone, this is a repost of a thread from a few years ago. Through various Google searches involving my problem, this appears to be the best forum to post on, so here I go. I am running Windows 7 x64 and will outline the following: 1) I noted that I began getting various browser redirects from sites when searching through Google (I have not checked if this was elsewhere). The browser would redirect me to websites such as newsfudge.com. 2) From this point I decided to attempt to run some scans. I had Microsoft Security Essentials installed however noted that it claims the service isn't running. When attempting to enable the service, it stated the service was not installed. - This was rectified. I uninstalled and reinstalled the application successfully. 3) Upon attempting to run both Malwarebytes and MSE (Security Essentials from here on out), I would reboot into the computer and began to notice that I would get a dialogue box that would explain my computer is about to be logged off because of a critical error. - Attempting to restore "Last known good configuration" did not resolve this. - The same dialogue box pops up when I try to restart in Safe Mode, I am currently posting this from my work computer. - I haven't been able to find a specific error within the System Logs so if there should be one stated please tell me what to look for. - I believe this occurs when MSE detects several infections, which appear to be different variants of sirefef. -- The last two variants of sirefef detected by MSE are: Trojan:Win32/Sirefef.AB and Trojan:Win64/Sirefef.P 4) I'm getting numerous Adobe Flash 11.3 installation attempts, which is where this problem all leads back from. Please help me save my computer from a reformat.
