20 Years of Computer Viruses
Tuxedo Jack writes "The Register reports that twenty years ago today (19 January 1986), the first computer virus, Brain, was discovered. By modern standards, this was a minor virus, and it spread by floppy disks, which is a far cry from the network-aware worms of today. Still, though, it was the first noted virus, and we've had twenty years of pain and annoyance from it and its successors. Happy birthday, Brain, you and all your little virus friends - just know we're doing our damndest to keep you from having more."
Not the first virus. It's the first PC virus, meaning IBM PC running DOS.
And, "The first PC virus was a boot sector virus called (c)Brain, created in 1986 by two brothers, Basit and Amjad Farooq Alvi, operating out of Lahore, Pakistan. The brothers reportedly created the virus to deter pirated copies of software they had written."
people did take them seriously, so seriously that they were interviewed by TIME, for more story, over to this link, but alas I think it was short-lived.. now they are kinda reduced to ISP and stuff
It uses to be that "worm" != "virus". Now days, it seems, many people call just about everything a "virus", when in fact, the "more proper definition" would be worm. Or, maybe I'm just being an old fart about this. It's pretty simple. If it is a _standalone_ program meant to infect machines, then it would be considered a "worm". If the malicous program where to "infect" other programs (say - via .exe, .com infector or MBR), it's a "virus".
That is, a "virus" will actually "attach" itself to a existing program (old com/exe infectors for eaxmple) or load themselves into the MBR/boot records. Then again, I see very obvious "trojans" get called "viruses!!!" all the time as well. Oh well :)
I don't think that's true, many old viruses used to operate mainly in the boot sector, and as such were infecting and spreading at a level beneath the OS (and beneath filesystems, for that)
I don't care what kind of disk you're booting, it has an MBR, and there might be a virus in it...

I've always believed that were it not for these Scientific American articles, it would have taken a lot longer for viruses to become prevalent. These articles piqued the interest of computer users (then synonymous with programmers) everywhere. For example, here's a 1994 comp.sys.apple2 post I just found of someone who was seduced by the articles into writing viruses.This is year 10 of me using Windows virus free.
Plus 4 years of DOS before that.
I read the first article about the theoretical possibility of a PC virus in either 1984 or '85, at this time most people scoffed at it, simply refusing to believe it was possible.
.com/.exe etc) and saved this to a text file on a bootable floppy, which was then marked read-only.
:-(
Anyway, having written quite a bit of asm code, I had no problems accepting the possibility, so for fun I decided to write a sort of vaccine:
Simply a small program that took a digitial signature of every executable piece of code (boot blocks,
Afterwards I could simply put in this floppy and reboot, whereupon the same program would compare the current signatures with those saved on the floppy.
The problem was to keep the original list updated each time I wrote a new program.

These two Brothers who created this virus are now millionries, have built Pakistan's largest ISP Brain Net and are also WLL service providers. See.. http://brain.net.pk/
This is the first computer virus. From 1975. With source code.
it spread by floppy disks, which is a far cry from the network-aware worms of today.
"The first implementation of a worm was by two researchers at Xerox PARC in 1978. The authors, John Shoch and Jon Hupp, originally designed the worm to find idle processors on the network and assign them tasks, sharing the processing and so improving the whole network efficiency."

Not only was it a "network aware" worm, but also a rootkit and a crude "grid" implementation.
