Norton and computer speed

My computer is running so slow that I finally contacted an outside tech group to come to my home and check it out.  One thing he told me is that the Norton software is a resource hog. He indicated that as a big part of my problem.  I wondered if this is true and if so, is there anything that can be done to "fix" this?

Don't know if this is the appropriate place for this question, but I ran all over the web site and couldn't find any where else.

Re: Norton and computer speed

Any real time AV product is going to have some effect on a system's performance. A number of years ago, Norton did have a problem with slowing computer performance. Since then, a lot of work has been done to minimize the performance losses. 

If you have already done a full system scan with Norton, maybe a second opinion scan for PUPs (Possibly Unwanted Programs) would be in order.  I would suggest a second opinion scan using the FREE version of Malwarebytes. You can find it here https://www.malwarebytes.com/premium/

If you wish, you can disable the Premium version trial to use the product as an on demand scanner by using the instructions here.  https://support.malwarebytes.com/docs/DOC-1033

Things happen. Export/Backup your Norton Password Manager data.

Re: Norton and computer speed

Hi ToniC:

Is your computer slow all the time or does this poor performance only occur when you're performing certain tasks (e.g., browsing the internet or playing a computer game)?

Further to peterweb's suggestion to run a Malwarebytes Free scan to look for PUPs that might have been missed by a Norton Full System Scan, what is the make/model of your computer, your operating system, and your default browser?  Did you have any other third-party anitvirus software (e.g., McAfee, Kaspersky, etc.) installed on this computer before installing Norton?  This would include any 30-day trial of antivirus software that was installed at the factory by your computer manufacturer.  Even if other antivirus software has been uninstalled, there may still be stray registry entries and files remaining on your system that are interfering with Norton, and we can provide links to the correct manufacturer's removal tool to wipe these last traces.

I've posted some hints about using Norton Background Tasks window (Settings | Administrative Settings | Background Tasks | Configure) and Norton's Performance Graph (Performance | Graphs | Usage | CPU tab - activity by nortonsecurity.exe should be shown as yellow peaks) to diagnose if Norton is responsible for hogging an excessive amount of system resources like CPU and RAM in C_Swords' thread My CPU is Being Abused by Norton.  That thread also contains a list <here> of some Norton settings that can be safely disabled and might reduce the system resources used by Norton Security without affecting your real-time malware protection.

Re: Norton and computer speed

HELLO EVERYONE

WHEN WE TALK ABOUT NORTON AND SPEED OF COMPUTER. WE HAVE TO KNOW WELL ABOUT SOME QUESTION.

What is Antivirus and why we use it?

antivirus is malware which affects our computer from an unnecessary resource like from the internet, other person pc and Pendrive etc. Due to this our computer becomes slow. Our antivirus continuous watch and analyze that happen in our system. 

When you use any antivirus the system become slow because when you open source at first it scans then it prints the result. select antivirus which has less scan time. It has also internet and pc both security available.so I prefer Norton antivirus which has three overlapping defensive layers, starting with traditional signature matching that compares new software to a database of known malware characteristics.

when their performance tested by German based LAB AV-TEST it score 100-percent results across the board against both known widespread malware and unknown zero-day malware.

so user selected based on their own idea and result in analysis

THANKS
