I am a rather unsophisticated computer user who is quite content with the latest version 3.x that I am using and the antivirus software I’ve chosen. I don’t t know how to backup settings for a upgrade to v.4. and wouldn’t know how to replace them if I did.
In trying to reach a decision, I’ve read many posts in other forums of the difficulties others encounter doing this upgrade with programs that no longer work, error messages, non-functional systems etc. I’ve learned that v.4 contains functions I’ve tried in standalone forms and don’t like (sandboxes etc.). I am frankly most uneasy about the prospect of changing to something that seems so much more complex and less user friendly than what I have now.
Simply, will v.3.X of the Firewall continue to be effective against internet malware and for how long? Can one upgrade only the Firewall without also adding the other System components? Am I being given no choice except to upgrade to v.4 if I want to remain a Comodo user?
