Galicia infects a computer's hard disk only if the computer is booted with an infected diskette in drive A:, in which case the virus infects the hard disk's Main Boot Record. The virus goes resident in memory the next time the computer is booted from the hard disk. Once in memory, Galicia infects all non-write protected diskettes used in the computer.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
Galicia activates on May 22nd after 12 o'clock when a non-existant drive is accessed. At this time it displays the following message:
Galicia contra =>telefonica!
which means "Galicia against Telefonica"; Galicia is the name of the North-West region of Spain, and Telefonica is the name of the company that has monopoly of telecommunications in Spain. The text is encrypted. The virus also tries to overwrite the MBR of the hard drive, but due to an programming error this function will be likely to fail.
Galicia is an encrypted virus.
