Milestone Antivirus is a rogue antivirus program that derives from the same family as Wireshark Antivirus. The program confuses people into thinking that their computers are infected and then attempts to sell its program as the tool to fix all protection problems.
Milestone Antivirus uses fake scanner and pretends looking for infections on your computer. Then it even provides a list of infections and claims that they must be removed by purchasing a full version of Milestone Antivirus. The program also generates various pop up messages warning you that your system is at risk.
Please remove Milestone Antivirus as soon as you notice it on your system. It’s not worth keeping it there.
