Submit new Malware

If you have discovered a file or files not recognised by Emsisoft Anti-Malware which you think could be a Virus, Spyware, Trojan, Worm, Dialer or other malware then you can send it directly to the analysis team by uploading it here. The analysis team will investigate further.

Uploading suspect files helps everyone get the best from Emsisoft Anti-Malware. The quicker we know about new malware, the faster you get an update to protect against it.

If you have more than one file, please pack them in a .ZIP or a .RAR file and then upload it.

It is a good idea to Zip or Rar any file before sending a file to anyone - especially if you have a dialup internet connection. Zipping or Raring files compacts them, reducing their size which in turn means less time is taken sending or uploading files.

Alternatively you can send your files to submit@emsisoft.com via Email. For larger amounts of files we can provide you with a FTP host too.
