Comodo is constantly improving its whitelist. This makes CIS more user friendly but does, in some circumstances, have some downsides.
Some malware may sometimes be trusted because it is signed by a trusted certificate or perhaps the vendor was trustworthy, but then changed their ways. It's even possible that some malware could accidently get whitelisted. This is rare, but it does happen.
Regardless of how it happens it's important to take action against this.
If you find malware that is whitelisted, but seems suspicious, please report it here. The name of the trusted vendor, or any other information, is also useful.
