When I tried to install the Winzip trial, Webroot told me that it is infected with something called ADWARE:InstallCore.
Winzip says it's a false positive:
I wish to inform you that there is no adware, malware, spyware or any other threats attached with WinZip apllication setup files downloaded from WinZip Website or downlaod links.
What does Webroot have to say?
Thanks.
