Aftr downloading at dat site i open d software named hotfile_premium_generator_keygen.exe and nothings change maybe i open itz 3times and after dat im curious of sofware so test it at virustotal.com and aftr d ysis 21 av said dat it is a virus. Only windows and n0d32 wont detect it. And wen i look at dat software. D software is gone? Im searching at windows explore but i cnt find it. So im worried. I used to chek my IdM TO SEARCH WEr my files is. It says d files is moved? So i try to smart scan using my eset smart security v4 updated as of now and then wen at while scanning i play game to wait until d scanning was done and wyl playing my firewall always pop up with red themes dat it was block ang incorect ip. But no ones using internet so i bothered maybe dat was d virus. Until it reach 90% of scaning i decided to download another a.v. Dat can detect dat such virus id use mozilla.
