A significant drop in total spam levels globally has been recorded by SoftScan, PC Advisor reports today, but the e-mail security company says the change should be regarded as a temporary one.
In December, SoftScan designated fully 90 percent of all scanned mail as spam, but over about the last week, spam rates fell by 30 percent. The company says the likely cause is a failure in one of the largest botnets in operation, leading to loss of control of thousands of client machines used to spray the junk e-mail.
SoftScan took the opportunity to point out that if spam rates continue to rise as they have been, aside from this blip, international anti-spam legislation will have to be implemented -- and enforced -- by the end of this year.
A growing number of experts and analysts, though, are saying that ISPs are in a position to make a significant dent in the botnet scourge, if they'll take up the fight in order to protect their customers.
