Sophos one of the world’s leading internet and data security company has mistakenly blocked web content at

In a recent article published on their corporate website, Sophos revealed that their system misidentified Google Analytics as Mal/HTMLGen-A.

Mal/HTMLGen-A is a Trojan that spreads through browsing and affects mainstream operating systems such as Windows, Mac OS X and Linux. According to Sophos:

Mal/HTMLGen-A is the threat name associated with web pages that have been classified as malicious by SophosLabs.

Web pages blocked by Sophos products as Mal/HTMLGen-A are likely to be used in an infection chain in order to infect users with malware.

A detection of Mal/HTMLGen-A indicates that access to a web page has been blocked by Live URL filtering.

If you are using Sophos Live Protection, you will get alerted about Mal/HTMLGen-A everytime you visit a website that has a reference to Google Analytics.

Sophos apologises for any inconvenience caused by this false positive, and would like to reassure customers that although warning messages may have been displayed related to Google Analytics, no other web content was blocked and that no action is required by customers to benefit from the fix.
