KillRDLL.A sounds like something out of an 80s hash and slash horror film doesn’t it?
In reality, however, KillRDDL.A is in fact a Trojan that replicates itself every time a user accesses a directory.
The Trojan tricks users by appearing to be a Windows folder icon but actually has a hidden extension.
The folders created by KillRDDL.A have been spotted with various names including -
- Angelina Jolie
- Clips
- Documents
- Favorites
- Flash Games
- Games
- My Documents
- My Folder
- Picture
- Video
- WallPapers
Note though that whenever the Trojan is executed it opens a web page that contains false results.
