Experts warn us that some filters are not efficient enough. They claim that some filters only catch 30% of the harmful e-mails. The reason for this being that the virus makers are quick at making new version and varieties of the code so it is hard to keep a traditional filter updated.
At SpamDrain we use artificial intelligence to continually refine the filtering process. This means that the filter can ‘learn’ what is spam and what is valid e-mail. The filter can therefore keep itself updated and quickly learn new tricks used by hackers to get their e-mails through spam filters.
This works quite nicely in Spamdrain when filtering spam and e-mail viruses. It would though be interesting to know if one could do something similar with desktop virus protection. I know that anti-virus companies have done some efforts in trying to “learn” the patterns of viruses and block viruses they don’t know about, but it’s unclear how well these techniques work.

We now see that virus level is back below 1 % which is more normal. Furthermore the dominating viruses aren’t actually viruses but phishing attempts.

Interesting to see  is that the spam rate seems to have followed the virus rate. Spam rate has been around 85 % but is now back to around 80 % again. Since many of the viruses are used to create botnets sending spam this is not that suprising.
