msrtn32 runs with rthdcpd.exe*32 - i have tried to remove them via remove programs and the no longer show up. Then removed them through command prompt. they still show back up.

when running they max out my processor and do nothing else. I kill them with task manager and they come back within the hour.

If they do nothing but max out the processor and won't allow themselves to be removed, they are malware.

what else would you call them?

@Marwin: The msrtn32.exe file looks very suspicious. No digital signature, no version information that identifies the publisher, and now MalwareBytes detects it as "Trojan.FakeMS".

I bought my desktop about three weeks ago and I already have this trojan virus along with five other trojan.fakems that show up and run very heavy. They are all in the msrtn32 folder and all exe files. Malwarebytes catches them, I delete them, and exactly one hour late they reinstall themselves and start running again. Doesn't matter if you delete the folder they are in. There is a total of 9 files associated with them. Somehow the file that makes them reappear exactly one hour later is not being caught by malwarebytes or hitpro or AVG Anti-Virus. There is little to no information on this but it pretty much uses so much resource and processor that it makes your computer almost useless.

@Steve: Sounds like there's some other file still remaining on you machine that reinstalls the msrtn32.exe file. If you like you can examine your computer with FreeFixer to see if anything suspicious is found.
