PcsProtector is a rogue security product in the WiniGuard family — the first clone of that line spotted in 2010. Same operators, new paint: fake scan results, scare warnings, and a paid unlock that does not protect the machine.
By late 2009 the family was already a revolving door of rebrands (The biggest rogue family; clones coming thick and fast). PcsProtector continues that pattern into the new year.
Do not buy it. If it is installed, remove it with the Malware Removal guide for Windows rather than licensing the scareware.
