What do you think?
Of course for the average and uninformed user a AV is kind of the gadget that will stop you from speeding, but for those who are informed, sensible and adopt the common sense approach when accessing the www, are these kind of products really needed?
If needed is a real-time protection really required?
I am asking this because in all this time I used computers (around 10 years) I never caught a single virus. Of course I had issues in the past but they were more spyware related, and for these different applications are needed (specific antispyware programs).
