a bit of nostalgia (virii)
my first contact with a computer virus was Ping-Pong, which infected our 10 Mhz 8086. Hopefully, a magazine was giving the solution (for free!): they were giving the hex sequence to search and replace !!!
While it was a working solution, it was not exactly 'user-friendly': Hey Grandma, launch PCTools 4.30, open the hex editor, then.... err, nevermind !
My 2nd interaction with a virus was Tequila: it kept re-infecting our computer. However, because our 20 Mb hard disk was very noisy, I could eventually recognize the sound of the virus infecting the MBR ! Instant detection, but once again, not exactly the most user friendly !
Hopefully, Anti-Virus softwares are now a bit better than 'listen to your hard disk' or 'search and replace yourself' !
