Malware detection

According to Google, the term malware, short for "malicious software," refers to any software specifically designed to harm a computer or any software it has installed. Malware can steal sensitive information (like credit card numbers or passwords) or send fake emails from a user's email account, often without the user's knowledge. Malware may include, but is not limited to, viruses, worms, spyware, adware, and Trojan horses.

Containers are automatically scanned for malware. If malware is detected, the affected container will be flagged. Google Tag Manager will not fire tags that point to sites where malware is found.

How do sites and networks get infected?

In most cases, affected users are unaware that there are tags that serve malware from their containers. Usually through no fault of your own, a network provider becomes infected when they install tainted 3rd party libraries or templates onto their websites, and subsequently transmit that malware to your site via the custom HTML tag that you published onto your website via Tag Manager.

Common symptoms of malware on your site can include unwanted URL redirects, pop-up ads, altered search results, the addition of unwanted browser toolbars or side-search bars, and slow computer speeds.
