No torrenting or clicking on .exe files I don't know for me. I tried to explain that to the, now deceased, owner of the laptop and it looks like they took my advice because the system seems clean.
You guessed correctly and while I'm going to install Kaspersky free as a replacement, I don't think I can do away with Comodo just yet, it's heavy yes, but its so versatile and Cruelsisters settings have not failed me yet (I think she's more of a legend than the software itself is at this point because it sucks out of the box).
Off topic but I'm trying to make a perfect VPN killswitch with it between me, my server and my customers. Its not easy because Im bad with FW rules but I think I can get there with some help.
