I have seen this for years.
Symantec and McAfee offer different opinions but then they make billions of dollars while not keeping you safe.
A decent anti-virus is necessary. The bloated mega-security suites do not catch the malware, these suites slow down your computers and they cost too much.
I attribute the safety and reliability of my work network to shared responsibility. I do the most I can do to keep the network safe. My co-workers’ contribution is as important. If there are questions we talk.
That’s common sense.
