How do I get rid of a program called Personal Antivirus? I have purchased the Malware Complete software and it doesn't detect this software that is giving me popups that I have a virus.

Any help would be greatly apprecaited.

Do the preliminaries. and post your logs in the Malware Removal sub-forum; not here.

This system has rogue (fake programs)
do this to close the rogue window. Repeat as needed.
Use ALT+F4 keys to close those rogue pop-up windows. Press and hold the ALT key & then press F4 key.
