Description BestWishes Family

These are very dangerous memory-resident viruses that affect .COM-and .EXE-files by standard way as they are opened or executed. On every fifth infection the viruses modify BPB of the Boot-sector of the current disk: reduce by one (zeroize if current day is Friday that falls on the 13th of any month) the contents of the word bearing number of clusters on the disk. "BestWishes.970" treats very rudely the memory and files and as a result may hang up the system and corrupt files.
