Virus when updating metatrader

 

Hi everybody, 

Does anybody have problem with virus when updating the build of metatrader ?

I'm using the freeware AVG, and it has detected a kind of virus (Win32/Themida) in the file ..\AppData\Roaming\MetaQuotes\Terminal\...\liveupdate\update\metatester.exe

(attached the printscreen of the AVG)
