Title: 100% CPU load while idle. No processes loading cpu are running
Post by: Synco on May 08, 2011, 01:41:18 PM
Hello, I've got a problem I can't solve and I need your help. I'm writing from my iPad so there could be autocorrect mistakes in the text below.
My pc is running windows 7, no anti viruses or firewalls. I haven't been using any av software since 2000 and it was fine till now, unfortunately.
When I started my pc this morning is was like superslow. To load all the icons it took about 15 minutes. In safe mode I've got the same problem. I barely can open a window or run task manager. So when I open the task manager it shows processes with 00 or 01% processor time. Mayb task manager sometimes is about 40%. But the task manager shows 100% CPU load. I can't install an antivirus or even open my browser. I downloaded drweb live cd but, booted from it but it didn't help so far.
Yesterday I was getting task scheduler error message during the day, but I didn't reboot my pc.

What virus could this be and what can I do about it? Thanks in advance.

as long as you don't tell which process shows the 100% CPU load, there's not much to add...

also:

... what do you expect ::)

yep, it wasn't very clever of me to not use av software...

There is the thing that there is no ruining processes using 100 % cpu. But cpu load is 100 % according to the performance bookmark in the task manager.

Hi there first off we need to determine if it is malware causing the problem

Download aswMBR.exe (http://public.avast.com/~gmerek/aswMBR.exe) ( 511KB ) to your desktop.
 
Double click the aswMBR.exe to run it
 
Click the "Scan" button to start scan
(http://public.avast.com/~gmerek/aswMBR1.png)
 
On completion of the scan click save log, save it to your desktop and post in your next reply
(http://public.avast.com/~gmerek/aswMBR2.png)

THEN

Download OTS (http://oldtimer.geekstogo.com/OTS.exe) to your Desktop and double-click on it to run it

The Main Problem is that I can't open browser, or it probably ail take few days justto open it. Is it possible to run it from a bootable disk somehow?

One bootable disc coming up - this will allow internet access and it has a browser, either chrome or FF not sure which

Please print these instruction out so that you know what you are doing

Latest version: v3.1.46.0

OTLPENet.exe
MD5=79209302A1AFB2490808DB890A815CED
Size: 127,222,215b / 121.3MB

Note : If you do not know how to set your computer to boot from CD follow the steps here (http://www.hiren.info/pages/bios-boot-cdrom)
Note : as you are running from CD it is not exactly speedy

I just returned home, looks like the process is wininit.exe. I googled that it  looks pretty much like the cause of the nuisance. But still I can't just end the process or download anything to this machine. If I found the alleged cause, I don't think I need to run the bootable thigy since it just checks the processes, right?

No the bootable disc will allow me to check for any malware on the system and then remove it.. If it is wininit, it may be infected, in which case I could replace it

I have had a look and I see that you have qip installed - are you aware of this and did you install it ?

Yep, it's an IM .never had problems with it.

There are 3 processes which load cow most. Wininit.exe, services.exe and explorer exe. I managed to lower the priority of these processes but CPU load remains the same. I tried to use online scanners to check these files (using firefox from the Ilive cd from your link in. This topic), they seem clear. I deleted all the tasks from windows/tasks folder. I even borrowed an avast Bart cd with the up to date virus bases, still nothing.

When I boot from the live cd, the task manager shows adequate CPU load which is 00-02% idle.
I tried to install malwarebytes' software but I can't run it. The process starts, loads 60kb into memory(according to the task manager) and remains the same with no signs of progress.

I'm quite desperate about this :(

Start OTLPE as you did previously from CD
Copy the attached Fix.txt to a USB

Thanks for help, essexboy. I just couldn`t wait anymore and formatted c: :) so the problem can be considered solved. Thank you once again. Now the first app I installed on my new system was avast.

Is your machine working normally now?  Is Avast working?  I would recommend updating the Avast definitions and running a Full and boot-time scans as well as updating and running a Quick MBAM scan and report back.

Yep, everything is working fine. Avast is working, just updated the definitions a minute ago. I will do the MBAM scan and will post it there as soon as I get my system fully checked.
