BetaNews is reporting that Google has a deal with WinZip to bundle both of these pieces of software with downloads of the popular utility.
WinZip quietly updated its download executable last week, which now weighs in at close to 4MB with the added Google tools. Users are given the opportunity to opt out of installing the Google software on the first WinZip setup screen; by default the tools are installed.
This is not the first time Google software has been bundled. As the article points out (we also blogged the news last month), you'll also find Google software included with downloads of InterVideo's DVD duplication software and with RealNetworks RealPlayer. Yahoo bundles its toolbar with downloads of Adobe Acrobat and Macromedia Flash.
