This is another very annoying malware popup that pretends to be a virus scanner, giving fake scanning statistics and virus detection.
The other side effects you may encounter from this malware is that you cannot access regedit or access your computer properties menu.
You'll need two programs to remove this malware:
HijackThis - http://free.antivirus.com/hijackthis/
Malwarebytes Anti Malware - http://www.malwarebytes.org/mbam.php
1) Download and install the two programs.
2) Boot into safe mode (press F8 during power up) and run Malware's Anti Malware program. Do an update and then a full scan.
3) Once that is completed, run Hijackthis and remove any references to plugie.dll, svchast.exe, svchasts.exe.
Boot into normal mode and the malware should be removed.
