PUP.Optional.PerfectRegistry

Short bio

PUP.Optional.PerfectRegistry is the detection for a registry cleaner . The use of registry cleaners is not advisable and some of them  use intentional false positives to convince users that their systems have problems. Then they try to sell you their software, claiming it will remove these problems. PerfectRegistry is a member of a family of Windows system optimizers that can be recognized by the GUI and the use of the file roboot64.exe.
