We have been using for some time 2 compression programs; WinZip v9 (6028) and WinRar v4.20 (64-bit). We haven't felt the need to upgrade these version, yet we have been inform we HAVE to buy the latest because these version security schemes are out date and we will be unprotected. We doubt this to be true, so like always, we turn to the Experts for strait-forward orientation. So the questions:
- Must we upgrade these versions to latest & why?
- Which is better WinZip or WinRar?
- Due to what has been in the press about the government
wanting back-doors to apps like skype & others, how secure are
these compression software? (see pic of each of their encryption security)
- Finally, should we consider buying another besides
WinZip or WinRar?
