On Wednesday, the Danish security company BullGuard announced it will offer its spam filter product as a free download. The BullGuard Spamfilter (download) integrates with Microsoft Outlook, Outlook Express, Windows Mail, and Mozilla Thunderbird e-mail clients. It runs on Windows 2000, XP, and Vista.
The BullGuard product relies upon fellow users to identify spam; once e-mail is marked as spam, all other Spamfilter users will no longer receive that e-mail in their in-boxes. It will be available within the spam folder instead.
According to Google's Postini, 2007 saw record spam levels, with as much as 90 percent of all e-mail traffic being unsolicited spam.
In addition to providing the free software, BullGuard is also offering Spamfilter users free, live 24-7 technical support.
