Applications that you use to protect your system can sometimes be the harbinger of even greater issues. Similar is the case if you are using two Antivirus programs in one system. An antivirus program is a must for every personal computer. However, that doesn’t mean the more you install, the secured your device will be. This is not that battle where the more weaponry you add to your arsenal, the better. In fact, it’s just the opposite! Obviously your system is going to be exposed to an ocean of dangers, but you need one, and only one antivirus to deal with everything.
