Go for paid one guys. If you guys are reading malware and ransomware attacks, free ones does not stops the attack, their features are limited. Get a paid one. There are a lot of tutorial videos on youtube with paid anti virus services.
Actually no. Free product can perform good as a paid product such as Avast Free for instance. You can strength your security with anti-exe app such as VoodooShield Free that will lock down your PC for good.
Free product can stop the attack if it have signature for it and behavior blocker. As matter of fact, Avast Free can stop the ransomware attack with its new behavior blocker modules.
I won't agree with you because a lot of my office and neighborhood peeps were telling me that they have Avast, AVG and other free tools for protection against KRACK, Duhk and bad rabbit, but none of them were capable enough to survive the infection. Result, they lost a lot of files. I had a paid service and it blocked all the malicious attacks. Free one does not guarantee a safety.
All those people were handling e-commerce websites (office colleagues) and have a little e-stores business (neighbors).
