Is Pet32.exe, MSPetServ or even RaveMon.exe something familiar you see in your PC? All these are unwanted worm that can infect your PC and slow down the performance speed, as well as being harmful to your PC.
MSPetServ should not be running at startup. It is likely a virus, spyware, trojan, or some other sort of malicious program. Use a virus scanner, and/or spyware removal tool to remove it.
This morning, I just stumbled some videos around..and I found this thing. To be honest, I also search for cracks that are available if I want to use a full program. And of course risking my computer’s life..lol
