Does it hurt your computer to have too many anti-virus/spyware programs installed?

by on August 26, 2012

I have Norton 360, AVG 8.5, Malwarebytes and spyware detector. Each one seemed to help at one time or another, but is it slowing down my computer? I am scared to remove one cause I might need it.

There’s always going to be some overhead cpu processing when it comes to running protection software, whether it be from spyware, adware, viruses, or hackers.

If your computer is modern (A few years old or less), up to date, and if the software isn’t fighting with one another, then I wouldn’t worry about it.

If you have a bang load of RAM (I generally go with 8GB RAM) you can keep all of them running. Norton, McAfee, etc run at a high rate of RAM and 4GB barely goes good while they are running.

Two antispyware programs can detect each other as an infection. Keep either Norton or AVG because Malwarebytes is not antispyware, it is antimalware

You should only have one anti-virus running at a time. If you have more then one, they will get in each others way.

I’m not sure what malwarebytes is. Its ok to have one anti-virus and several spy-ware removal programs. You only want one program that governs you computer’s security. Having other programs that you manually open, run a scan, remove stuff, and close is fine.

Having multiple antivirus program can often create instability in the operating system, and also causes slowness.

Get rid of AVG and Norton 360 and just get avast free.

Having multiple spyware / adware removers is not damaging, in fact, it is recommended by many tech guru’s

Two much real-time resident protection is going to cause problems. Worry more about getting a good clean back up. There are tons of backup software out there in the market but a good disaster recovery plan in place can save you in the end.

well TO MY KNOWLEGE IF YOU HAVE MORE THAN ONE ANTI VIRUS PROGRAM THEY FIGHT AGAINST EACH OTHER AND LET THE VIRUSES SLIP ON THRU AS avg DOES IT ONE WAY AND NORTON DOES IT NOTHER WAY’ SO REALLY YOU NEED ONLY ONE TO DO THE JOB RIGHT.getting MALEWAREBYTES IS A GOOD THING TO HAVE ALSO AND CAN WORK TOGETHER WITH THE ANITI VIRUSE T KEEP AWAY SPYWARE..Good LUCK AND SORRY FOR THE BIG LETTERS AS IT’S STUCK AS OF NOW.

All of this will conflict.

Avg likes to work alone.

From what I have read, you need malwarebytes as a stand by in case you get a trojan.

Looks like norton 360 has a firewall and ID protection. You need that.

If you have the avg free, you do not have a firewall or ID protection. There are free firewalls. If you paid for it, you do.

If you drop norton, you would absolutely need a firewall.
And if you bank online and use a credit card, you need the ID protection.

If you uninstall avg, do not forget to remove it from the add and remove programs..

The same thing with norton.
