Rogue:MSIL/Zeven is a type of malware that uses scare tactics to coerce users into purchasing Win7 AV. Once Rogue:MSIL/Zeven is inside a system it will display fake security alerts and pop-up warnings. Rogue:MSIL/Zeven will also infect the browser and cause it to display fake warning pages and block a victim's access to other websites. The victim will be coerced into paying for the non-existent full version of Win7 AV in order to remove the purportedly detected threats. Do not fall for this scam and have Rogue:MSIL/Zeven removed from your system upon detection.
