Pastika is a polymorphic file virus. While spreading, it infects the system with the Jindra boot virus.
Pastika activates on 21st and 22nd of every month. At this time it overwrites the beginning of the hard drive. While overwriting, it constantly displays this line:
Jindra & Pastika je zde!!!
This is Czech and means "Jindra and Pastika are here".
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
