Are antivirus apps guaranteed to keep the blacklist for email addresses and domains up to date?

Antivirus applications typically employ a variety of mechanisms to detect and manage threats, including the use of blacklists for email addresses and domains. However, there is no guarantee that these blacklists will always be kept up to date. Various factors affect the timeliness and accuracy of blacklist updates, such as the frequency of updates provided by the software vendor and the evolving nature of threats.

Vendors may release updates regularly, but there can be delays or lapses in updating their lists due to resource constraints or the speed at which malware or phishing schemes evolve. Moreover, not all antivirus applications prioritize the same aspects of threat management, which can lead to inconsistencies in how often blacklists are refreshed.

Therefore, it is important for users to be aware that while antivirus software aims to provide robust protection, reliance solely on their blacklist for email security may not be sufficient. Additional vigilance and protective measures are often necessary to ensure comprehensive security against email-based threats.
