Solid protection with genuinely useful features. Rock-solid protection with tons of features – today’s best antivirus. Bitdefender is also one of our picks for best antivirus overall….Which Antivirus Software Has the Least System Impact?

The lightest paid antivirus program we tested is Bitdefender Total Security, which slowed our test laptop between 7.7 and 17 percent during active scans.

Which antivirus slows down computer the most? Plus that will degrade your system performance because in addition to your processor and memory, your hard drive is busy pulling up all the files that Norton is scanning. Whenever you use internet Explorer all your browsing history remains in the depths of your PC.īut Norton itself having such high usage is probably not a bad thing: it’s probably just doing a complete system scan and is very busy. How do I fix a slow computer performance? If you have only installed Norton, you should try disabling Windows Defender. In this case, you should disable or uninstall the other antivirus program. Norton security will slow down the system performance if any other antivirus program is installed on the computer system. In the Startup Manager window, do the following: In the On/Off column, uncheck programs that you don’t use to prevent them from launching when your computer starts. In the Norton main window, double-click Performance, and then click Startup Manager. How do I stop Norton from slowing down my computer?

How much memory is installed on the system? To me the issue is not Avast but something else causing the slowdown even though disabling part of Avast helps. I think everyone is confused because f post 2 that suggest Windows Defender is part of Avast which it is not.
