ESET Can't clean ~dulla^@204~

I've been using ESS for about a year, I have been relying on it since...
But few days ago I noticed a problem, that corrupts my office files.... when i try to open files on notepad It says tomething like.... "~dulla^@204~ ... "
It seems ESS can't protect me (us) any longer; unless something happens soon!
Please give me a solution for this "dulla" thing.

 

1/ A screenshot is worth thousands of words... Google returns absolutely nothing relevant for "dulla" which strongly suggests you haven't even posted the message right.
2/ Why do you even think this is related to ESS in any way whatsoever?

 

Here is the problem, whenever i try to open an office, Zip or Pdf document... it says corrupted.... when i open word documents on notpad all i read is like the attached image.
which means My computer is infected with this "~dulla@^204~" stuff. I read somewhere tht kaspersky found some adware... but still can't recover (repair) those corrupted documents.
N.B.1. I tried to open those documents on other computers but, it is the same; still corrupted.
2. I've noticed that after this happens whenever i run word, excel or acrobat.... another application (~ 42.5 Kb size) is created insystem32 folder and runs automatically.
