The second program infected will increase by 269 bytes. The third through fifth programs infected will increase in size by 270, 271, and 272 bytes, respectively. In all cases, the virus will be located at the beginning of infected programs. The file's date and time in the disk directory will not be altered. V270x appears to not do anything besides replicate.
