When this virus activates it will just repeatedly play three melodies. Infected files grow by a variable number of bytes, so their length becomes a multiple of 51 bytes in length. This virus stays resident in memory, but it will not infect other programs when they are executed. Instead it will search for a file to infect when files are created or deleted, a subdirectory is created or the access mode of a file is changed. A few other functions may also trigger an infection.
The virus uses a random number generator to decide when to become active, and if it does, it will start playing 5 minutes after an infected program is run.
Based on the settings of your F-Secure security product, it will either automatically delete, quarantine or rename the detected program or file, or ask you for a desired action.
