FraterPerdurabo: How come people are using 7Zip instead of Winrar? I have personally always used the latter.
I used to be like you - always using Winrar over 7z. Then one day I discovered that RAR files created after the 40 days install were being saved without passwords!
i.e. I would password protect a new RAR I was creating and then try to open it afterwards and it would open straight up without any password.
That did it for me. I uninstalled WinRAR that day and converted to 7Zip.

ZivilSword: After using Avast! for over five years and
not a single virus was found (but instead nagging me more and more with update messages, slowing down my system), I tried a new strategy. No anti-virus at all. Yes I know you guys scream out, and Windows did the same, but I am (not) using this for a year now and there is nothing suspicious happening, no data loss, no mysterious errors. Everything fine and better than before because nothing needs to nurse me and check my data and such.
I have to say it is no strategy for all people because you really have to know what you are doing and don’t click on every download link in the internet. But apart from that I feel more free than ever. :)
As long as you have a good firewall (and are careful with USB devices - turn off Auto Run or hold down Shift while inserting) you can get away without having AntiVirus turned on 24/7.
I don't have the courage to have no AntiVirus at all though - I keep mine turned off and just run a scan every now and then just to be on the safe side.
