Malware online scanners

Here is a list with online malware analysis services, updated as needed. Every time you feel a file is suspicious or you receive a file from an untrusted source, it’s recommended to scan it with one of these online services before to open it. Please bear in mind that even a friend’s computer can be considered an untrusted source, since it can be malware infected and files sharing is a good chance for malware to spread.

The main advantage of these online scanners is that the submitted files will be scanned with many antivirus engines, reducing the chances for a virus to be unrecognized and therefore labeled as inoffensive — sometimes this is called multi-engine scanning. If an antivirus fail to detect an infected file, there are others that may recognize the infected code inside the file.
