Get into Safe Mode With Networking and download Hitman Pro. If you can’t open it, use Force Breach Mode (hold left Ctrl key while opening Hitman Pro until its window opens). After you clean up some of the malware, use MBAM and SUPERAntiSpyware to finish it off. Also, it would be good if you could copy-paste HiJackThis log here after completing above steps.
I managed to install HitmanPro, but when I ran the program, it said that I have no internet connect, which is obviously not true, as I am online!
I then went to install the other programs you mentioned while in Safe Mode for Networking, although I didn’t get the chance to load them, as after I did this I now have the problem that every time I run Safe Mode for Networking, my laptop crashes before Windows even opens, it just completely shuts down.
