What Antivirus (no pun intended) for PC are you using?
mine is expiring AVAST & I am not that happy with it.
What are you using.....besides Free Windows 10 Defender..?

I have used free Windows for the past few years, zero problems.

Don what is the link?

I'm pretty sure it's on your PC, just go to Settings and enable it. It probably will prompt you to update it.

Windows Defender Antivirus.

Click "OPEN WINDOWS DEFENDER SECURITY CENTER" at the following page to access it:
https://www.microsoft.com/en-us/windows/comprehensive-security

Also using free windows with Win10 ...

Most recent update stops Coronavirus, but only through Wireless connection.

For most people Windows Defender built into Win10 will be fine, best to avoid Avast or AVG (There the same) as they were caught selling peoples data by default. (If you knew where to look you could turn it off)
Bit Defender is a good free Anti-Virus program, however if you are going for paid for, Sophos Home Premium has come out top over the last few years.

No better virus killer then windows defender,,
As none know Windows weaknesses better the Microsoft

Thanx everyone now activated

what about android tablets ?

Can’t answer that, i can only tell you thatin apples ios virusses get no chance because you can only load apps from the appstore... and they are all virus free..

Thanx bachus but there has to be something for android also.

"Do I need virus protection on my Samsung tablet?
Security software for your laptop and PC, yes, but your phone and tablet? ... In almost all cases, Android phones and tablets do not need antivirus installed. Android viruses are by no means as prevalent as media outlets may have you believe, and your device is much more at risk of theft than it is a virus.Mar 18, 2019"

I've never used a virus program on my tablet. Both my laptops have Windows 10/Chrome.

So long as you do not root your Android Phone/Tablet and only load apps from the Play Store you should be fine.
Before installing an app always make sure check what it has access to and make sure you are happy with this.

Thanks everyone for the helpful info I needed.

Bill, to my knowledge, the playstore is well known for its virusses and trojans..

Opposite to apple that checks every app manually before its placed in the appstore
Google does not infertere with people placing apps on the playstore..

Maybe this changed in the past 2 years, but it used to be quite bad even on googles own playstore
