Host Machine: PC compatibles.
|
||
|
||
Derived from: Search-HD.
|
||
|
||
This virus is really a modification of the Search-HD virus. The
|
||
display code has been replaced (no display occurs on reboot) by code that
|
||
disables the SYS program. The SYS program itself is not modified, but any
|
||
attempt to execute SYS will result in the program not being loaded.
|
||
Instead, multiple reads to the source and target drives will occur (to
|
||
simulate the SYS activity). The normal SYS message output is displayed
|
||
by the virus at the appropriate time. This virus will successfully avoid
|
||
being removed by SYS. The virus does no damage.
