Is Dirty Mouse a virus?
NO, Dirty Mouse is not a virus. Its a joke or prank program intended to entertainment purposes only.
The definition of a virus is an unwanted computer program that was written to purposely damage computer systems or replicate itself. A virus is usually manifested by a destructive or disruptive effect on the executable program that it affects. Dirty Mouse is not a virus!. Dirty Mouse does no harm, does no damage and is not destructive. Dirty Mouse might be disruptive to the victim you play the prank on, but that is the intention of a joke or prank. Dirty Mouse is simply a fun gag program that is completely harmless. We would not be in business for 15+ years if we created viruses. We will challenge any anti-virus company that claims our software is a virus and causes damage to computer systems.
Read this FAQ to see our response to major anti-virus vendors flagging our software is a "virus". You need to look closely at your anti-virus vendor and see what they are detecting our software as. Below you will find information about Norton AntiVirus and other vendors responses to our inquiries.
After a full system scan in Norton AntiVirus 2009 we noticed the following screen appearing show us that we had an "infection". This screen shows our Fake Format utility, but it is the same screen that appears for all of our joke software.
After looking closely at the "risk" of the software you will see the RISK TYPE of "Joke program". It states "A program that alters or interrupts the normal behavior of your computer, creating a general distraction or nuisance". This sounds to us that a "Joke program" is not a virus.
Reviewing the help for the security risk of these "joke programs", below you will see the text:
Inside of Norton (all anti-virus vendors include this option) you can set the Security Risk Categories for your anti-virus scan. If you UN-check the option for Joke Programs our software will not appear in the anti-virus scan (see below)

As with any anti-virus or anti-spyware software, you can choose the option to NOT include "joke" programs in its detection.
This will prevent harmless joke programs from appearing to be viruses or spyware.
Dirty Mouse nor any of the software we create are viruses.
The guys over at NirSoft are also feeling the pain of the big anti-virus companies going too far with "anti-virus" protection. We encourage you to read this blog posting for some good information regarding this topic. We feel their pain!
