Some spyware, viruses and other bad stuff is delivered by email. UseBestMail helps you keep this malware out of your computer because, unlike spam filters and most other spam blockers, UseBestMail doesn't have to download the junk mail. You can keep it on the server where it won't do you any harm, then delete it from there.
This may become even more important if a newly discovered vulnerability becomes widely exploited. It has been discovered that pictures embedded in emails can cause virus infections -- something nobody thought possible until recently. If this vulnerability becomes exploitable it means that simply downloading and opening an email can cause a virus infection. Previously one had to click on something to trigger the infection.
Some experts believe that this vulnerability may be be too difficult for virus writers to exploit and doubt we'll ever actually see it. But whatever the outcome, those who UseBestMail have an extra layer of protection, not only from this new threat, but from the many run-of-the-mill viruses, trojans and other threats circulated by email
And finally, we emphasize that, while UseBestMail is helpful, it is not designed to be an anti-virus or anti-spyware product. You should equip yourself with a good anti-virus software tool such as NOD32 (from ESET, LLC), which we recommend. There are a variety of good anti-spyware products available also. We use Lavasoft Ad-Aware.
