Welcome to being a valued member, NullByte! Your graduation from lurking makes you as fascinating as the fact your preferred form of computing is on a linux distro.
I am looking forward to finding out which one. In fact, I'll be on my way to your configuration thread now!
Even though you preceded me, Welcome!! I'm really happy to have found you on here. The next phase of my adventures in self-education is learning Linux.
I'm not using Qihoo TS, it's my favorite Free AV.
When it comes to Internet Security, Comodo is my favorite and in the second place Emsisoft Internet Security.
On linux, I have ClamAV with custom settings (more signatures) and Snort.
