Hi Paul
No WinZip is not a virus, it is a legitimate application, and it is not free . . .
However, it does come down and install itself by hiding with other applications you install
You don't need WinZip on your PC, because Windows natively supports Zip files, so the best option is to uninstall it . . .
Open the Settings App, go to Apps, then find WinZip in the list of installed Apps and uninstall it from there . .
