I created this poll to find out who out there is adamant about using antivirus program, who doesn't and to inform other who don't understand or know the pros/cons of using an antivirus program. Below are just a few pros and cons that I am aware of. I am sure there are more. Pros It provides added security to what your OS firewall provides Can allow you to visit most website with impunity Capable of caught and detering programs that can harm your PC Adds to your reassurance that your PC should be safe Cons Some believe that a AVP can be a resource hog Some believe that a AVP schedules scanning at inappropriate times Some believe that it can slow your PC down when gaming, etc Some believe that they are cautious enough to have never had to worry about viruses If you use Win7, Vista or XP you may already be using Windows Defender. You will need to check your OS updates to see if it's there or not. Or you could be using MS's Security Essentials (although I haven't seen that as part of an OS update). So, you need to actually check your installed programs and your updates to make sure of what you have before voting. Anyone can clarify if there is a antivirus program in place for non MS os's. Thoughts on the issue?
