Windows 7 Home Premium, Emachines E725 laptop.
Several times while browsing ordinary websites I will get the sudden display of "Windows Security Warning" and the usual message of infection. When this happened I closed the message box and the tab and ran Malware bytes. Nothing has ever been found.
Tonight it happened again so I investigated a little and found this in my IE history:
I decided this infection was real and got started looking how to remove it. I went to the "Remove Windows Safety Wizard Removal (Uninstall Guide)" page and downloaded the Rkill iexplore.exe and updated Malwarebytes. I restarted and F8ed my way to Advanced Boot Options and selected Safe Mode with networking. It started up normally, got to the Users page, I selected the main one, typed in my password and the puter restarted. Huh. So I tried again and typed faster. The puter at first started to start up in safe mode then restarted. I tried one more time but this time when it got to the Users page I left it alone and counted. 12 seconds later it restarted by itself. So, I can not enter Safe Mode to start the eradication of the infection.
I guess that confirms that this bug is on my laptop. I started normally and ran a full scan using Malwarebytes. It found nothing. What do I do next?
