Personal devices and the information they carry are incredibly valuable to their owners. It is only natural to want to protect your device like a royal family fortifying a medieval castle. Unlike medieval castles that depended upon layers and layers of protection (moats, drawbridges, spiky gates, etc.), personal devices thrive on just one defense: a devoted guard called antivirus software.
Increasing your personal device’s security detail with more than one guard, or antivirus software is actually less effective than using a single, comprehensive option. Microsoft operating systems recognize the detriment of running two antivirus software programs simultaneously for real-time protection. Microsoft Windows automatically unregisters additional programs so they do not compete against each other. In theory, if you have a Microsoft device, you could run on-demand or scheduled scans from two different antivirus products without the operating system disabling one of them. But why invest in multiple software where one will do?
If you do not have a Microsoft device, here is what could happen to your device if you run more than one antivirus program at a time, and why you should consider investing in only one top-notch product.
Fight Over Potential Viruses
Antivirus programs want to impress you. Each wants to be the one to catch a virus and present you with the culprit, like a cat with a mouse. When antivirus software captures a virus, it locks it in a secure place to neutralize it. If you have two programs running simultaneously, they could engage in a tussle over who gets to scan, report, and remove the virus. This added activity could cause your computer to crash or use up your device’s memory.
