Guardpe.com is a misleading website that promotes a rogue security program called Antivirus Scan. Normally, you wouldn't visit such websites but if you got hit with the Antivirus Scan malware then you will be constantly redirected to Guardpe.com instead of the requested web page. A new Internet Explorer window may pop up like every one or two minutes saying that you need to purchase Antivirus Scan in order to remove the infections and to protect your computer against new threats. Please do not buy anything from Guardpe.com. If you have Antivirus Scan malware on your computer, please follow the Antivirus Scan removal guide.
