Re: Oblig XKCD obit
In the early-mid 1980s, if you had a PC, there were various tools you needed...
McAfee - anti-virus - esp when "sneaker-net" was the norm...
Norton Utilities - such as NDD, (Norton Disk Doctor), SD (Speed Disk), etc
XTree - for File management under DOS
4DOS - a replacement for command.com
RIP Mr McAfee....you will be remembered by "old hands" as a significant player in the early years of the PC and by "younger hands" as a bit of a rascal !
