More Than One Antivirus: Good or Bad?

Is it okay to run more than one antivirus program at the same time? I always thought it was, but I’d like to hear an update on it from you. Thanks!

The simple answer is, “No, it’s not okay to run more than one antivirus program at the same time.”

It makes sense that we, as computer users, assume that if we have more than one antivirus program on our computers, we will be better protected from outside threats. We all think that if one of them doesn’t catch something, the other surely will. Well, this just isn’t true. Using more than one program (or even multiple versions of the same one) will likely cause you some problems. Here are a couple of the biggest ones spelled out for you.

You will use up too many resources on your computer. Doing this will more than likely slow your system down and it will truly affect your computer’s performance.

You could receive false virus alerts. Antivirus programs work by using an actual virus to detect another one on your computer. So, if you have more than one piece of software running at the same time, each program will think the other is a virus. The two programs will conflict in many ways, but this is one of the majors.

Now, as I’m sure you have already figured out, it’s recommended that you only install one antivirus program on your PC. So, if you have two of them on your computer right now, you should uninstall one right away. Now, you might be wondering how you should pick which one to keep, right? Well, choose the one you’re the most familiar with. For example, if you have Norton and McAfee on your computer, which one do you know the best? Which one is going to give you the protection you need, but also ease of use? Those are just a couple questions you should ask yourself before you decide.

Also, you might want to look into the expense of each program you have. If one is going to be a little cheaper to upgrade, etc., you may want to go with that one. Keep in mind also that there are several free antivirus programs available today, so maybe that could be a deal breaker for you. Just weigh all your options, and make sure you choose the program that is going to be the best for you and your computer.

If you already have two antivirus programs on your XP computer, you can uninstall one by going to Start, Control Panel, Add/Remove Programs or under Programs and Features in Windows Vista or Windows 7. From there, just find the name of the one you want to get rid of and hit the Remove or Uninstall button. That will take care of the program and all of its components as well.

Now, if you still don’t think you’re going to be protected enough, just make sure you keep your virus definitions up to date and keep everything clean. Run your virus scans on a weekly basis as well. If you do all that, you should be just fine with only one antivirus program. And believe me, your computer will thank you. No more conflicts, no more slow downs and no more trouble. The best is yet to come!
