mc21.tmp, mc22.tmp, mc23.tmp


We received a lot of user requests regarding mc21.tmp, mc22.tmp, mc23.tmp files.

Usually the strange driver files are located in the Windows\Temp or in the user temp folder.

Mc21.tmp, mc22.tmp, mc23.tmp are related to Spyware Doctor software installed on your computer.

Note! The latest version of Spysweeper includes Spyware Doctor.

Spyware Doctor creates new driver file at every Windows boot. After the loading driver into memory Spyware Doctor deletes the driver file because it is not required for Windows system.

This why the file doesn't exist in the Windows Temp folder.

Quick test

It's very easy to check if mcXX.tmp files are leigitimate.

  1. Open Spyware Doctor, choose Settings.
  2. Select "Startup Settings".
  3. Uncheck "Run at Windows startup" and restart your computer.
  4. Open RegRun after reboot and check that the "mcXX.tmp" driver doesn't exist in the Drivers list.
Good luck!

They say
"RegRun Security Suite is one of those very rare tool kits that no one who is serious about protecting their PC should ever be without. This toolkit covers all the bases when it comes to eradicating the attempted security threats from malware that we all face - daily. The near real time tech support, direct from Greatis, is nothing sort of superb, something that can be rarely said these days! I have no hesitation in recommending this suite to anyone."

Bob Schmulian:
Absolutely love it and have recommended to many people!

Ian Robinson:
It is FANTASTIC! It has saved my life on more than one occasion since I purchased it less than 6 months ago. I now would not run my system without it... it's worth many times the cost! The service and support are terrific. Helpful - friendly - and accommodating; and generally a reply is received within 12 hours. Just great.

Theodore Soucie:
Since RegRun was installed my system is more stable. I use to experience freezeup daily. I have not had a crash.
