Hi! I am new here, so if I am doing anything the wrong way I appologize and please let me know. So, I have been infected by this thing that seems to be going around lately, "System Check". First it closed my webbrowser and sent up a bunch of messages about not being able to save and harddisk errors. Without thinking I, sadly, selected the option to scan my system when prompted, for some reason believing it was legit. When it started it seemed obvious that it was fake so I tried shutting it down. Finally I had to resort to turning the computer off. When I started it again similair things happened and my desktop and Start-menu were empty. Before finding this place I booted in safe mode, entered Regedit and removed qguaayvrII.exe from the HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run, in the hope that it would stop the thing from starting. (Hope this did not do any harm). Then started again in normal mode. Start-menu and desktop is blank. Changed settings for the Start-menu so I got "My Computer", "My Documents", "Controll Panel" and "Run" back. All folders appear empty except for the Windows folder. Started Firefox with "Run" and am now going through the steps in the "UPDATED 5-step Viruses/Spyware/Malware Preliminary Removal Instructions". So far I have installed Avast and it updated right after installation. Rebooted and got a message from Avast that a Trojan had been blocked. I installed Malwarebytes and updated it. I am now in the process of scanning with Malwarebytes. Will continue the 5 steps and post logs. I would be very thankful for all and any help with this!
