Blue Square have noticed a marked increase in the number of SPAM emails received by it’s own staff and clients over the last 3 weeks.

Although the McColo hosting servers (that provider a significant amount of malware and botnet traffic) were closed down 5 months ago, the botnets are back up and running again and causing many a bulging mailbox!

Tighten up your spam filters, don’t open attachments from untrusted sources and hang on for dear life…..
