For the free Antivirus , avast is a pretty good choose ,
however this time F-Secure give their top product to be a giveaway ,
It worth it to take a try .
And not only can use on Windows system , but also on MAC or your smart phone ,
such as Android or iPhone .
If you real don't like it or don't get used to , you can reinstall avast back in anytime you like ,
after all avast is free , there is no time limit .
But don't forgot , seems F-Secure will ask you to remove other security tool , such as Zemana and Malwarebytes ,
if you want to use them both , you must remove other security tool first , after F-Secure install success , than install other security tool back .
( P.S: don't forget to export the security tool's setting , after reinstall back , you won't need to resetting again)
I highly disagree, for me, F Secure is one of the worst, there are no settings to configure, nothing to tweak. Malware detection wise it's just hit or miss. Giveaway is very generous indeed, but I don't feel like F Secure is even worth to be paid for , It's just that empty, only my personal opinion.
