Also you need some good malware trojan scanner. I use Malwarebytes free edition and it finds things my antivirus doesn't. Also if you run the EXE and it turns out that is a virus and your definitions were out of date and it takes control of windows where you can't even get to a boot screen, then you need a good windows image restore program like Acronis True Image.
Security is a complete misconception when downloading anything off a torrent.
Make sure you have a reliable anti-virus in place and do a full scan of the program before opening it.
Ya no problem in downloading the exe file from torrent but before opening it scan with what ever antivirus protection you have
i am using window 7, which have windows defender and avast at the same time.. is it ok?
It should be fine, but like I said, do a scan of the program before opening it.
