Adri is a Hungarian virus. The virus overwrites the MBR of the first hard drive after one month of the first infection. The virus infects EXE files during execution and appends its excrypted virus body to the end of such files.
It does not display a message when it activates, thus the problem with the hard disk will be visible after booting the PC next time.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
Detailed instructions for F-Secure security products are available in the documentation found in the Downloads section of our Home - Global site.
