Hey guys, I'm writing here because I am quite desperate. Today, the malware Real Antivirus installed on my PC, despite using Sophos Antivirus and Spybot Search and Destroy. Now, I have a "new" desktop, with a blinking ad in the middle and a balloon popup in the taskbar advising me to download anti-spyware and leading me to a realAV-website. Haha. I tried several things suggested on the internet, like deleting RealAV files and registry entries manually, but my PC won't even find them. The often described RealAV-task is not in my task manager. I asssume this is because I have quite a severe case. :-/ When I downloaded Malwarebytes (my last hope) and tried to install ist, it was cancelled and like 16 windows opened, saying "invalid floating point operation". I would appreciate help of ANY kind very much! Thanks a lot in advance. Analconda
