|Men who use condoms still have a chance to impregnate women. Does this mean they should stop using condoms altogether?|
What a fantastic analogy.
It might seem silly, or like everyone in the world is overreacting to a threat you've never experienced. I get that. I used to have the same mindset. I've been working at a computer repair shop for the past several years, and I can tell you with certainty that this
|Can a website put anything malicious on your computer without you knowing?|
Is 100% possible.
But it's not often the websites fault. (i.e., if a virus came in via facebook web traffic, facebook as a company isn't (necessarily - conspiracy theorist) the one doing it).
It's happened to me personally (work and home), where all of the sudden "Windows 7 Antivirus Plus!" Or something pops up for no apparent reason and starts closing out other applications. So yeah, it's necessary to have antivirus programs that detect these things because
1.) We can't rely on Microsoft to modify their operating system to render these attacks useless. I suppose it would be wrong to expect them too as well. The same thing that makes Windows so susceptible to malware is the same thing that makes it greatly customize-able.
and 2.) We [/i]can[/i] definitely count on the malicious intend of other people/groups.
Because you've never been hit with a virus doesn't mean that viruses don't exist. I can almost guarantee that one day you'll wake up, turn on your computer monitor and be like "Oh shit they were right."
But yeah, not being an idiot helps with keeping the viruses away as well. That is, porn (y'know, the kind that you view in your browser without sandboxing it..), run-down game sites, things like freeze.com that offer you "FREE MP3 SONGS", bearshare or limewire or frostwire or whatever they call it nowadays.. You get my point.
