We have Norton 360 and we get the occasional 'spam / junk' e-mail, but in the last 4-5 days we've been getting a lot more spam - and all of it is for Penis enlargement pills, pills to increase sperm volume, pills to help satisfy her for longer., pills to increase your sexual performance.....

I've not had any of this type of spam for years, so why would I suddenly be getting spam like this?
and more to the point, shouldn't Norton 360 be stopping it coming into my inbox or junk mail folder?
