If you come across an unknown file and want to know what that file is, you could either google it up or you could head straight to whatisthatfile.com.

Whatisthatfile is a database of information about files which you can search by the file name. You can enter a filename and see if this file is a dangerous trojan, malware, or simply a standard Windows file. For example, I searched for scvhost.exe, and I got the following info.

The site doesn’t claim to have the information about every file or every virus/trojan. But it is constantly updated. Actually, anybody can add to the database. If you come across a file or virus which is not included in the database, you can add the information about the file yourself.
