Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Question:

Why is this site blocked with browser error "MALWARE_GENERAL, BLOCK-MALWARE"?

Environment:

Cisco Web Security Appliance (WSA), AsyncOS versions 6.x and above

The notification code below

Notification codes: (1, MALWARE_GENERAL, BLOCK-MALWARE, , 0x0021aee7, 1220506712.572, QAAAAQAAAAAAAAAAKP8ACA==, http://www.domain.com/) is due to the fact that the mentioned URL has a low web reputation score (by default WBRS equal to or below -6.0) and therefore is blocked by the default setting in access policies for the WBRS filters.

The reason for the low reputation score is that the site has been detected, either currently or historically, as sending spam/viruses/trojans by our spam traps.

If you want to bypass WBRS scanning for the website, you can whitelist the site using URL categories, as they take precedence over Web Reputation filtering. Please refer to "How do I manually whitelist a webpage on WSA" for details on how to manually whitelist a web page.
