What Is That File

When was the last time that you checked your Task Manager for potentially dangerous files? I’ll admit that I don’t do it all that often because I put a lot of faith in my antivirus software, but I have been known to Google apps that I don’t recognize. I’m sure you’ve done your fair share of Googling filenames, right?

Today I finally decided that there had to be a good site out there that I could use to lookup unknown files, in particular I wanted something that wasn’t popup infested! I went through dozens of sites before I came across WhatIsThatFile.com. It has a somewhat slick interface that shows matching filenames as you type in the search box. It will highlight files that are potentially dangerous, such as a virus or malware, and give a brief description of each. It will even let you know if an application is a prime target for infections, such as Internet Explorer (iexplore.exe).

Right now it is home to information on over 3,000 files, which is a rather large selection. Anyone can edit the information for a particular file, or add a file themselves, but they are subject to the approval of the admin. In a way this is like the Wikipedia of filenames!

Let us know in the comments below where you go to lookup unknown files on your computer!
