What was the advantage of this over 'Terminate and Stay Resident'?
- linuxlizard 8y agoMaybe stealthiness? TSRs could be viewed with the right tools, IIRC. This seems like a technique to hide code?
- msravi 8y agoSo yes, this was a TSR, except that it resided in unaccounted for memory. Also, since you put it into the MBR, it would get loaded into ram automatically with every boot, and no fiddling with autoexec.bat or anything where it could be easily discovered. All this of course, in trying to understand the fascinating world of viruses.
