Have you ever come across a suspicious file that you were unsure of?  Sure!  A lot of us have. Most of the time, we just delete them and move on with our lives.  There is an alternative to just deleting and moving on.  Our goal is to have a malware free community, and you can help by submitting suspicious files you find to us to examine.


To help improve the way malware is detected and removed, the Malwarebytes Research team collects malware from VirusTotal.  VirusTotal is a free malware analyzer that helps users decide if a file or website is malicious.


If Malwarebytes did not block a file or website you believe is malicious, use VirusTotal to submit a malware sample.

Submit a malicious website
