In mid-January I unfortunately accept a "flash upgrade" repetitive query and this lead to the activation of the rogue " Vista Anti-spyware 2012" on my computer.
The additional problem except the fact that I have all the scans asking for the deletion of some inexistent virus is that my ventilator got crazy and after some strange acceleration it began to run at maximum, so that i immediately shut down my computer.

After some research from my netbook (not infected) about this problem, i understood that it was probably a rootkit called "zaccess" (not sure) which has taken control of some core processes of my computer. I achieve to install "MalawareByte Anti-malaware" on the computer (despite the virus, preventing me from launching executable files) and ran it. It detected some potential threats which i deleted.

After that, the rogue scans stopped and the computer seemed clear. Nevertheless, the problem wasn't solved. My ventilator had one more time the same problem: after ten minutes, it began to have an unusual behavior and then ran at maximum (and the UC was at 100%). According to me, my computer is still infected and perhaps is used for some calculation or whatever.

I'm now asking for some help to delete this threat from my computer.

Additional information:
My OS is Vista 64 bits.

PS: Would the window "backup system to a previous state" delete the infection?

Hello, Welcome to BleepingComputer.
I'm nasdaq and will be helping you.

If you can please print this topic it will make it easier for you to follow the instructions and complete all of the necessary steps.

If still unable to run .exe files please navigate to this page.


Click on the .exe box and download the .zip file.

You will find under Usage instructions the proper way to execute this file.

p.s. You can download it from a good computer and copy the file to the desktop of the infected computer.

Please download ComboFix from any of the links below, and save it to your desktop. For information regarding this download, please visit this web page: http://www.bleepingcomputer.com/combofix/how-to-use-combofix

Link 2

* IMPORTANT !!! Save ComboFix.exe to your Desktop


1. Close any open browsers.

2. Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

3. Do not install any other programs until this if fixed.

How to : Disable Anti-virus and Firewall...

Double click on ComboFix.exe & follow the prompts.
  • When finished, it will produce a report for you.
  • Please post the C:\ComboFix.txt
Do not mouse click ComboFix's window while it's running. That may cause it to stall

Note: If you have difficulty properly disabling your protective programs, refer to this link --> http://www.bleepingcomputer.com/forums/topic114351.html

If ComboFix stalls for more than 30 minutes stop the process. Run the file again. Post the log for my review and let me what problem persists with this computer.
