I have been trying to fix this computer for a while now with no luck

sytem 

Windows Vista Home Premium

 

I've scanned with malwarebytes, finds nothing....ran ccleaner to get rid of thousands of temp files, 

 

kaspersky scan found trojan.multi.regrun.ba and bb  but could not clean them

 

100% cpu usage, 70-80% physical memory usage...system is soooooo slow

 

high cpu processes change constantly

 

I am trying to avoid formatting the drive if I can.  I would appreciate help if I could get it.  

 

Thanks,

George

Hello!

I am having the same problem.

NOTE: I NOT a trained malware removal technician, so i can not tell you to remove anything, however i can help you check what it is that you have.

I have the poweliks backdoor, with similar side effects to those that you have mentioned.

You can download a poweliks scanner/remover here http://download.eset.com/special/ESETPoweliksCleaner.exe

I would recommend that you ONLY SCAN with it, do not enter yes.

Once it says "poweliks detected" close the program and create a post here http://www.bleepingcomputer.com/forums/f/22/virus-trojan-spyware-and-malware-removal-logs/ and wait for a trained technician to actually do the removal.

Thanks, I ran that scan, and actually chose yes to remove it, and the system seems fine.  I am going to monitor for a long time tonight to verify.  Thanks so much!

Now that you are back at the desktop, you should scan your computer with an anti-virus program. ESET has a free online scanner that you can use once to detect and delete infections. I suggest you use this to make sure there is no other malware present. The online scanner can be found here:
