Description
Multipurpose Internet Mail Extensions (MIME) encoded files can be crafted to hide a malicious payload. When the MIME encoded file is presented to software that decodes the MIME encoded files, such as an email client, the malware is released. Scanning these files as part of the regularly scheduled scans tasks will mitigate this risk.
