Google Pack includes Google Earth, Desktop, Picasa, Toolbar, Photos Screensaver, Talk and Video Player.
It also includes partner software such as Mozilla's Firefox, Adobe's Reader, Norton Security Scan, RealPlayer, GalleryPlayer HD Images, Skype and now Spyware Doctor.
"As part of this partnership we are providing an exclusive version of Spyware Doctor for Google Pack users," said PC Tools chief executive Simon Clausen.
The free edition offers the usual spyware detection and removal as well as real-time protection with PC Tools' new File Guard technology.
The free version is lacking a few features compared to the full version, such as Cookie Guard, Keylogger Guard, Startup Guard and Browser Guard. The free version also lacks phone support.
