Bopspam protects your PC from spam using a variety of methods, such as checking lists of known and probable spam. It also uses a technique called 'Bayesian' filtering, which learns what is and isn't junk based on what you indicate each email to be.

Registration on the Bopspam website is quick and simple. You start with a 30-day trial and then pick a price scheme of either £30 or £50 per year. The latter allows up to 1Gb worth of emails to be sent annually.

There is no software to install as all the prevention work is done on Bopspam's computers. All you need to do is tell Bopspam up to 10 email addresses you'd like monitored and change your email software to use Bopspam.

It will check every email you receive before you see it so, if it is spam, you never have to download it, which will save dial-up users a lot of time.

Bopspam sends a daily email with a list of what was blocked so you can correct any mistakes. The system will learn from incorrect blocking and pass them through next time.
