Actually, I think that was 58200 variants on 1 machine. *** Not likely, worms (it did say worm) often use signals (a mutex) to ensure only one copy is running on the machine. The count is likely the number of computers thought to be hosting (or having hosted) the worm (I didn't look). ***

I was providing a generic example. Plug in your own numbers to get a result that's meaningful to you. I can't do it from here.

I use a dimmer to turn my lights on and off slowly. I've been running dimmers ever since I starting lighting. I've never lost a bulb yet. I've never had a virus since I started computing in 1983 either. :-) -- --- Everybody has a right to my opinion. ---

Very interesting. I will start a new thread and cross post here...on this topic. I'd like to see what others say but my intuition says your thesis is correct. Linux may have a smaller "surface area" than Windows for malware vectors to latch onto, but at the end of the day it's not immune--in fact, I was surprised to learn recently there were two security patches to the Linux kernel in the last six months. For a while I believed the hype that somehow Linux is immune from malware. > > What do you see as "malware" in Windows that's a serious problem? > > *** > Aside from the obvious "clueless user" syndrome - there are worms being > used as botnet distribution mechanisms.

Interesting. And if the worm does not leave behind copies of itself it will not be detected by a user running a weekly or biweekly full scan?!

The worse (most successful) animal viruses are the ones that don't kill their host--they are just an annoyance, so the host does not try to kill them; think dog or cat with fleas. > *** > > Or stuff automatically installed?

Is it a source for malware to infect your computer? I was recently surprised (since I'm coding an ASP.NET web application right now) that microsoft.com home page did not have any JavaScript (when I looked at the HTML source code via my browser). I was surprised--I don't like JavaScript that much because it's server side and essentially is just eye candy for the user (but saves a round trip to the server, so it is useful for performance I guess)--but I was --unless I misread the source code, via View | Source --shocked that MSFT did not have any JavaScript on their home page. Maybe it's been turned off by so many browsers that it's passe? Or perhaps so many different versions of it out there? At one point I think MSFT had their own flavor of JavaScript that was not compatible with the others. RL

And if it's unprovable Sir Karl Popper would argue it does not exist (scientific method). RL |
