Pet32.exe | MSPetServ

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.

Recently, my PC has been suffering from such “disease”. Normally transfer through your USB drive / pendrive / thumbdrive. I found this very irritating.AVG Free Anti Virus cannot detect Pet32.exe. Luckily, I’ve installed Spybot – Search & Destroy in my PC and able to denied the changes that Pet32.exe want to make to my registry. However, it didn’t do any good, the virus is still inside my PC.

How can you know if your PC is being infected by Pet32.exe?

If you are not able to double click your drives (say C drive, D drive or any partition of your hard disk) to access it, but only can access it through right click > open. Then your PC has been infected.


  1. Download Kaspersky Antivirus trail version
  2. If you have AVG Antivirus, you have to uninstall it before you can get Kaspersky running.
  3. Scan your hard drive with Kaspersky, it will detect pet32.exe, delete it.
  4. Go to your hard drive (and/or partition) , DO NOT double click. Use right click and open.
  5. Go to tools>folder option>view>show hidden files & please uncheck box ” hide protected system files(recommendation)” and press OK.
  6. Look for autorun.inf and delete it.
  7. Restart PC.
  8. It should be fix by then.

  2. @curryegg,
    You’re welcome. Yes, once you double click, it actually activates the virus pet32.exe, which cause you cannot open the drive. The autorun.inf is written with a short script that force the system to autorun pet32.exe once double clicked.

    It’s my honor to share my knowledge with you. If you have the same pet32.exe problem, maybe you can try the other method without Kaspersky antivirus (refer to my update).

  3. Well, forget about AVG Free. The detection rate is awfully low and there is no background intelligent scan which could effective prevent those malicious code from auto executing. I personally prefer Avira and Avast.

    Right now my system has a running combination of Avira, Avast and Spyware Terminator. The entire process may slow down the system a little bit but you will be worry free knowing that every aspects has been securely protected.

    Technically I should use a firewall but to date my system has yet to be compromised due to the fact that Avira has a rootkit scan, Avast has a pretty robust network shield and Spyware Terminator has an impressive HIPS. Plan to use Comodo if my system is still able to support a 4th prevention / protection system. =)
