Winzip use deception tactics when offering a seemingly free version of winzip. It is not unresonable to accept that free cut down versions are offered when so many software providers offer basic versions of their software for home use, with full blown versions available to purchase. On the Winzip website, they claim to offer a free version.Only after downloading and installation do they allow it to be known that it is in fact a 21 day trial for which you will have to purchase a license. This is a deception and I would not trust any (particularly software) company that employs such tactics. I uninstalled immediately and 'cleaned' my system. Usually my cleaner utility finds a few things to clean after a browsing session but after Winzip contact, there was loads. Even more reason to mis-trust them. Check out open source and genuinely free alternatives. Read reviews - there are several very good offerings. I should have done that before trusting winzip.
