Absolutely Not!

Aside from both being CRAP-period. In 25 years of computer consulting I thank both Norton and McAfee for many dollars paid to me to correct their single use problems, antivirus programs run together cause conflicts.

Horrible programs both.

In fact, if you are running Windows 10, Windows Defender is already included and the best defense against viruses. Then for other Malware like spyware, and others, the best defense is the paid, realiime version of Malwarebytes from the Malwarebytes web site.

To clean up cache files, and other garbage, use CCleaner from Piriform software site.

All other download sites are conflicted and load more garbage than they clean. Spyware comes from the routine software download sites. McAfee particularly is rampant with frequent bad updates.

So, my referrals on this are the Microsoft Essentials.... MSSE for Windows 7 and older and Windows Defendor provided with 10, and Malwayebytes and CCleaner. No conflicts among those three.
