I need to upgrade my security and currently run the AGV free anti-virus on my laptop. This tells me that I have no firewall operating and potentially open to malware etc. They want to charge me for this and I don't mind paying. I have looked on the net and there are some free ones which are supposed to be better than AVG according to write ups. I need to get up to speed with this as I have just purchased a new phone so I can download my banking app, worried about hackers. Can anyone point me in the right direction as I need to educate myself in order to stay safe on the laptop and phone. Thanks.
