My question is: WHY DO YOU NEED SO MUCH ANTIVIRUS ON YOUR SYSTEM?
Maybe two is way enough, but all 3 and 4? come on guys! My recommendation if you feel you need more antivirus apps, two at most! Sometimes when you have more than one you are stirring up a war on your pc between the apps. Soon your pc might start malfunction, then you'll have to be running to a computer technician.....
Now my advice, keep one, or maybe two. If you choose two research them out and see if they will have a conflict with each other.
Secondly, be careful where you surf... Thirdly save your downloaded files in a one folder, so u can scan before opening... Finally, update your antivirus and scan regularly...
Trust me guys, its not worth killing yourself over how much more antivirus you need to add to the 3 , 4, 5 you may already have.
