AV AntiSpyware is a clone of a widely spread rogue anti-spyware program called MS AntiSpyware 2009. This program is advertised and installed through the use of Trojans. When these Trojans are installed on your computer they will display fake security alerts stating that your computer is infected. When you click on these alerts it will automatically download and install AV AntiSpyware onto your computer. AV AntiSpyware is also advertised through the use of advertisements that pretend to be online anti-malware scanners. When these fake scanners finish they will state that your computer is infected and then prompt you to install AV AntiSpyware.

AV AntiSpyware is installed to automatically start when your computer loads. When started, it will scan your computer and list numerous infections that will not be removed until you purchase the program. These infections, though, are all fake and are only being shown to scare you into thinking you are infected. While running, AV AntiSpyware will also display numerous security alerts, warnings, and prompts when you perform certain actions on your computer. For example, when you attempt to download a program it will pop-up an alert stating that the download may be malicious. Other alerts, such as ones labeled infiltration alerts, will state that your computer is under attack. All of these alerts are fake and are only being displayed to further trick you into thinking you have a security problem on your computer. One of the security alerts that you will see are:

Spyware Alert!
Your computer is infected with spyware. It could damage your critical files or expose your private data on the Internet. Click here to register your copy of AV AntiSpyware and remove spyware threats from your PC.

Last but not least, AV AntiSpyware will display a fake Windows Security Center on your computer. This window will be an exact replica of the legitimate Windows Security Center except that it promotes AV AntiSpyware rather than providing general security recommendations. With all of this said, please do not purchase AV AntiSpyware if you find it on your computer. Instead use the free removal guide below to remove this software and any related malware.
