What are the best Windows 8 and 8.1 antiviruses

Windows 8.1 will reach the end of the extended support in 2023 and customers on Windows 8 had to upgrade to 8.1 in 2016, to remain supported.

What we wanted to underline here is that the two systems are close to their end of life and you should make a move towards Windows 10 as soon as possible.

However, there are still many users that can’t do that for many reasons. If you’re one of them you also need to know that an outdated system is more vulnerable.

That is why we definitely recommend protecting it with a dedicated antivirus that will secure your system and your data at all times.

The search for the best free or paid antivirus software has been going on for years and years, and it’s pretty hard to decide a winner.

We performed searches and tests and came up with a list with the best Windows 8 and 8.1 antiviruses that you can use right now.

Another great addition is the PC Cleaner tool that will help you erase any tracks from any of your browser and apps so that your data and activity can remain private.

It also comes with a software updated tool that can keep all your installed apps up to date, avoiding any errors and crashes in the process.
