Edgar

From Homestar Runner Wiki

Edgarware, or "Edgar the Virus Hunter," is Strong Bad's anti-virus program on the Compy 386. He used it in the email "virus," in which it detected 423,827 viruses on the Compy. The viruses caused a Flagrant System Error and ended the computer before Edgarware had time to try to remove them.

This is the startup screen for Edgarware:

Edgar's weird name may be a reference to Norton AntiVirus, or the entire program's name may be a play on Microsoft's "Dr. Watson" which apparently is to help fix your computer, though if it is needed it is usually too late.

Edgarware makes an appearance in the virus-themed Main Page 22.

There is another software similar to Edgarware called Edga Jr., which first appeared in long pants.
