Tere is a typical files virus. It stays resident and infects COM files when they are executed, renamed, deleted or their attributes are changed.
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
When files are executed from floppy drives, Tere first checks if the floppy is write protected by attempting to read and write back the boot sector of the floppy. The virus does not infect COM files longer than 64909.
The virus contains this text:
This is Estonian and mean "Hello World!"
Tere was found in the wild in Estonia in February 1997.
