Virus causing high CPU usage.

post #1 of 20
Thread Starter 
I think I've picked up a virus from somewhere

My computer felt like a Celeron this morning so I checked task manager and guess what I found:

Crazy CPU usage, it jumps between 40-90%. The usage is jumping around 70-90% on Core 1 and it's all over the place (20 - 100%) on Core 2.

Malware bytes just finished a quick scan and got the following:

Trojan.Agent Folder C:\\Windows\\System32\\SYSTEM32
Trojan.Agent Folder C:\\Windows\\System32\\SYSTEM32\\DRIVERS
Trojan.Agent Folder C:\\Windows\\System32\\SYSTEM32\\DRIVERS\\._rtl818 7.sys
Trojan.Agent Folder C:\\Windows\\System32\\SYSTEM32\\DRIVERS\
tl8187.sys
Trojan.Agent Folder C:\\Windows\\System32\\SYSTEM32\\DRIVERS\\RtlProt. sys
Hijack.DisplayProperties Registry Data HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\Curre ntVersion\\Policies\\Explorer\\NoActiveDesktopChan ges


The CPU has just come down quite a bit after running the scan, despite it claiming no action was taken.

Anyone got any ideas?

System Idle seems to be the biggest one there - of course that isn't important.

It's a process called System which has the description NT Kernel & System. This will suddenly sneak up with very high usage. The usage only creaps up if I scroll on a page, reload a page or do anything on my computer. It's fine when it's idle.

I'm certain it is something.

My computer was fine last night and now it's lagging almost as badly as IWNet.

My mouse delay is insane, my keyboard input lag will be instant one minute and then up to 3 seconds the next. Youtube videos seem to go normal speed then lag into slow motion.

It's a virus, I'm certain.

Do you see any processes that should not be there in the list?

Also if you do a selective boot up with just windows components does the computer behave the same?

Haha! Sigged!

Also, boot in safe mode and scan.

Try to run Malware bytes as others have suggested. I work in the industry and this software has saved me more times than I can count.
