Hello!

 

Recently on my fathers laptop (HP Probook with WINDOWS 7 Professional 64Bit) and he noticed it started running really slow. Eventually it would Blue Screen.

I ended up going into safe mode and downloading Malwarebytes which found two counts of Trojan.FakeMS. Once I quarantined them, I restarted normally.

The system ran so much smoother on boot up, but after 5 minutes it would start loading, and loading and would freeze. So I checked Processes and saw two

explorer.exe running, one of them was at 1,400,000K. So I did some research and a forum said it was possibly a root kit. So I ran TDSSKiller, and sure enough

it was a rootkit.

 

After all this was done, I still have three things that duplicate and max out the CPU usage within minutes :

 

dllhost.exe *32

ctfmon.exe *32

and dllhst3g.exe 32*

 

I have no clue at this point what to do, and there wasn't many forums with help. Any suggestions?

I think I resolved it

 

I ran Combofix and it seems to have fixed it!

 

It's been running for almost 2 hours without any of those .exes running. I rebooted twice.

Works like a charm
