some of best anti viruses - 2021
The Ultimate Comparison of antivirus software
This a non-exhaustive list of notable antivirus and Internet Security software, in the form of comparison tables, according to their platform (e.g. desktop, mobile, server, etc.) and their operating systems (e.g. Windows, macOS, Linux, Solaris, Android, iOS, Ubuntu Touch, Windows Phone, etc.).
The term "on-demand scan" refers to the possibility of performing a manual scan (by the user) on the entire computer/device, while "on-access scan" refers to the ability of a product to automatically scan every file at its creation or subsequent modification.
The term "CloudAV" refers to the ability of a product to automatically perform scans on the cloud.
The term "Email Security" refers to the protection of emails from viruses and malware, while "AntiSpam" refers to the protection from spam, scam and phishing attacks.
The term "Web protection" usually includes protection from: infected and malicious URLs, phishing websites, online identity (privacy) protection and online banking protection. Many antivirus products use "third-party antivirus engine".
This means that the antivirus engine is made by another producer; however, the malware signature and/or other parts of the product may (or may not) be done from the owner of the product itself.

Why news media is in crisis & How you can fix it.
India needs free, fair, non-hyphenated and questioning journalism even more as it faces multiple crises. But the news media is in a crisis of its own. There have been brutal layoffs and pay cuts. The best of journalism is shrinking, yielding to the crude prime-time spectacle. My digital news .in has very few young reporters, columnists and editors working for it. Sustaining journalism of this quality needs smart and thinking people like you to pay for it. Whether you live in India or overseas, you can do it here
