Wrar390.exe and Wrar393.exe are NOT Trojans, in fact they are the setup files for WINRAR application (WinRAR is a popular shareware file archiver and data compression utility)
FML... I hope you know what that means..
I've haven't used WinRAR for awhile, But I remember a trojan being blocked going on a website, but I'm pretty sure it was one of them two,
Even though in my Security listing, It only shows 1 trojan.
