Lately I’ve been looking on the digital signatures on those files that push various types of unwanted programs. This morning I found a new file in the FreeFixer database called digital-photo-2013-11-nov.pdf.exe, digitally signed by Artur Kozak.
You can see who the signer is when double-clicking on an executable file. Artur Kozak appears in the publisher field in the dialog that pops up. You can also see the Artur Kozak certificate under the digital signature tab.
So, why am I warning you about the Artur Kozak file? Check out what the anti-virus programs report about the file:
TSULoader, InstalleRex, Win32.Adload and Adware.Downware are some of the detection names reported by the anti-virus scanners.
Hope this helped you avoid getting some unwanted programs on your machine.
Where did you find the Artur Kozak file? What was the file called?
