Viruses on the Internet are everywhere.
No one knows who sends them, but everyone knows when they arrive.
In the flood of antivirus products on the market, now, in their basic functions, all of them are free, in addition to the classic Windows Defender, AVG, Avira, Zone Alarm, etc..
They are all good, some are slower, some are faster. Professional antivirus products, for example Kaspersky, are quite expensive.
I installed on Windows 10 this antivirus that always worked well in the free version, so much so that I bought the paid version: Malwarebytes.
Rather essential, without graphic pages, it protects instantly and quickly.
Previously I had installed Avira and AWG but they slowed down my computer which is not recent.
Malwarebytes in paid version, does not slow down my computer and so far I have never had virus infections.
