G-Archiver is an archival tool for Gmail. It lets you backup your Gmail emails to your computer. It’s been discovered that it also has a darker purpose.
G-Archiver costs US$29.95, and it does what it claims. To use it you enter your Gmail username and password, and it downloads emails to your computer as a backup.
Unfortunately the program has also been sending people’s usernames and password to the program’s creator (identified as John Terry).
If you’ve used G-Archiver before then uninstall it and change your Gmail password.
