Behaviors displayed by Antivirus Action (AntivirusAction) are subject to its introduction peculiarities. Like most fake system utilities this program is available both for manual upload and intensively distributed by special agents targeting system vulnerabilities. The behavioral difference is not critical though. It is just that, where the rogue antispyware installation is a fruit of the efforts of the above agents, its popups are shown in the order that keeps users unaware of the adware name. In the wild, where it is not uploaded by user, Antivirus Action does not show its scan window prior to other windows starting with its alerts which do not refer directly to it or wear a mask of system notification. Where it is a user who uploads the adware, it generates its popups in random order.
Get rid of Antivirus Action as it blocks legit programs. In some instances, most of the programs installed at the infected computer malfunction.
