Trojan circulates as fake McAfee patch

Emails pretend to be a security update for a virus which does not exist

Experts are warning of a new Trojan that is spreading by masquerading as a patch for McAfee's antivirus software.

Emails have been spammed out pretending to be a security update for a virus called 'Kongos 31' which does not exist. The email contains a link to a web page hosted in the US that looks very similar to the McAfee download page. 

"Users receive a spoofed email message instructing them to click on a link to immediately download and install a patch from McAfee," said internet monitoring firm Websense.

"The link in the email takes users to a fraudulent website that appears to be the legitimate McAfee security site. The patch hosted on this page is actually a Trojan downloader."

Users are warned that McAfee does not send out this kind of email and instead alerts users through its own software.
