The Avast Antivirus utility incorporates an integrated Mail Scanner feature for scanning inbound and outbound emails.

However, some users have said on Avast’s forum Avast Antivirus doesn’t scan emails. This leaves some users’ PCs vulnerable to email attachment viruses.

What’s so important about the Mail Scanner in Avast Antivirus?

One thing to note about Avast Antivirus’ Mail Scanner feature is that it’s for email client software. That means it’s only intended to scan messages handled by email applications like Outlook and Thunderbird. So naturally, web-based mail services like Gmail have their shields.

However, the Mail Scanner shield in Avast Antivirus is more critical if you utilize Outlook and other email client software. It’s not uncommon for malware authors to spread viruses with email attachments. Therefore, Mail Scanner is one of the four core shields in Avast Antivirus.
