I'm certainly no expert when it comes to home PC security, I just read all the comments about this AV and that AV and how one may be better than the other with none being 100%. It strikes me that the very best security is to invest in a good backup app and use that to make disk image backups frequently. If your PC becomes infected you only have to reinstall from your latest backup and your back to near enough where you were with no problem of trying to remove viruses and you can just ignore ransomware etc.. . With this setup only the addition of one of the free AV apps would keep you from any regular infection. Or am I wrong with this view? Is there any downside to this stratergy? Do I really need to join the paid AV bandwagon?
