Do you know what AV Pipeline is?
AV Pipeline is a fake security tool and should be deleted from any system it has embedded itself within. As is typical of these type rogue applications, AV Pipeline will infiltrate a computer system via Trojan infections. All scans and virus alert messages displayed by AV Pipeline are in fact fabricated and should not be trusted, so remove AV Pipeline. AV Pipeline may enter into a system via downloads directly from its affiliated website, by uninformed users. However, this is not the only means of infiltration employed by AV Pipeline. This dubious application might also spread via Trojan infections or browser exploits. The use of a legitimate anti-spyware program is highly recommended to detect and remove AV Pipeline from any infected computer system.
In non-techie terms
AV Pipeline is a fake security tool, and should not be trusted under any circumstances. Remove AV Pipeline as soon as is possible!
