Hi lkori9, Antivirus Security Pro is a fake antivirus program from WinWebSec family. It enters user's computer using exploit kits which are being distributed using malicious websites and drive-by downloads. You shouldn't trust this program, moreover you shouldn't buy it's full version - it's a scam created by cyber criminals. Notice that this program doesn't have an uninstall entry in one's control panel, furthermore it blocks execution of installed programs (including antivirus and anti-spyware) and blocks one's task manager. Such behavior is typical to fake antivirus programs - it reports non existent security threats hoping that PC users will be scared into buying it's full version which would supposedly eliminate all the security infections. Buying this program would equal to sending one's money (and banking information) to cyber criminals. The right way of treating this program is it's removal from your computer. As this program blocks one's Internet browsers you can either use Safe Mode with Networking or a retrieved activation key to eliminate this fake antivirus from your computer.
