I wonder why are you giveaway the antivirus.
Anybody checked the files ?
I didn't check the files, but I can answer to this.
Since I asked for a key for mobile security solution, I tried to see about the Eset keys he provided.
Now... I will not install a security solution from a forum, however good are the intentions of the one who provides it. (Sorry OP)
I tried, however, the keys on the stock Eset mobile security. And they did not work
So I'd say that the provided installers may be slightly (?) changed to actually accept the key.
Of course, I will not say anything else about them. They may be trojans, they may have whitelisted some malware, or they may be only changed for the key, I don't know. I am just too paranoic to try that out.
