How’s your computer behaving now ?

Since the 1st OTL scan until now,the avast did not come up with the warning again. Does it mean that we have successfully deleted the virus?

Aha. 8) We need to some post cleaning…

It is necessary to uninstall the ComboFix :

[*] Click Start (or
http://amf.mycity.rs/pg/images/VistaStartButton.png
) then Run.

On Windows7 or Vista you may use Start Search field if Run is not available.

[*] In the line of text type in (Copy) the following:

ComboFix /Uninstall

Note that there is a space between " ComboFix " and " /Uninstall " .

[*] then click OK (or press Enter ).

Wait for the uninstall process is complete.


Re-run OTL an click on CleanUp!
Re-run AdwCleaner and click on Uninstall button

I recommended to you to keep MCShield if you will.
It will prevent infection by computer via USB flash drive, mobile phone or any other memory card.
And not only will prevent infection, but will immediately clean Memory card or external HDD

Know that in our tests, USB Disk Security is many times had failed to protect your PC while the same tests MCShield hase passed. And MCShield is lightwere and free.
I would recommend that you leave a MCShield and remove USB Disk Security. But your will :wink:

Thats it :wink:

I’m done with your final instructions.Wow i think the virus is really gone. Thanks to you. Your instructions are very clear. I will do all your recommendations. You really saved my day. ;D
