Usually, such fake AVs as Cloud AV 2012 drive people nuts, especially because of never ending alerts and notifications about critical threats, etc.
However, they are not so dangerous after all and I think shouldn't be compared to more sophisticated malware, rootkits, worms or viruses. It's just well designed but useless application which reports non-existent infections. That's all. Then bad news is, however, that Cloud AV 2012 comes bundled with Trojans and sometimes even rootkits. There are usually a number of Trojans that can download additional malcode onto the infected computer and rootkits may hide/block legitimate antivirus programs. But that's not all, the rogue program modifies Windows Hosts file to redirect internet traffic to either infected or sponsored websites involved in click fraud schemes.
So there you go. I know it sounds like a lot of job, removing Cloud AV 2012 and associated malware is not that difficult after all. First, run rootkit removal utility. Then scan your computer with recommend anti-malware program. Finally, restore Windows Hosts file using Fix it utility. You may even use this debugged registration key 9992665263 to make your life and removal procedure a little bit easier. Just follow the steps in the removal guide below. If you need extra help removing it, please leave a comment below. Good luck and be safe online!
