Quote from GTS:
Not sure what you are advocating here by your statement that the odds of getting a virus by opening an attachments is low. Just to be clear, I'm not saying not to open any attachments, I'm giving the reason you need to have AV on your machine even if you don't engage in risky behavior.
I guess what I am saying is that I feel my risk of getting a virus is very low given my personal behavior. To say that opening PDF and JPG files is risky is alarmist in my opinion. Also, I feel that anti-virus software can be viewed as a virus itself in that it hogs system resources and slows your machine down. I guess it will take me getting hacked to make me change my mind.
