My point is that taking 5 minutes to install a free anti-virus program like AVG makes this 1990's "scary virus" mythology a completely moot point, nothing to discuss any more even by Apple zealots as it solves the problem entirely.
Let's not be hyperbolic. Most independent tests say AVG is really good, if not the best. However, the detection rate is still not 100%.
Coincidentally, AVG Free's detection rate is around 98% by most tests, some less some more, which happens to be the same % as of Virus's written for Windows. Statistically speaking, and assuming all other factors remain the same, this means a Mac with no antivirus is as likely to get a virus as Windows is with AVG. 5 minutes or not, this shows how poor Windows security is.
We've never had a virus on any of our Windows machines, ever. Never a malware problem, never a hacking attack, nothing, zippo, nada. All because I took 5 minutes to install an anti-virus program and made sure everyone understood not to double-click executables in emails.
I don't believe this for a single second. Back in the early/mid 2000s, there were times when it was literally impossible not to get a virus on XP. Literally, a computer just sitting there connected to the internet would get a virus even with a good anti-virus installed. Back then, a detection rate of 99% one month would be 70% the next month - the pace was insane. I've been using Windows since 3.1, and one of the jobs I had in high school and college on and off was fixing computers. I've seen the Windows XP install screen so many times it has been burned into my retinas. Do not kid yourself into thinking you never had a virus - you probably just did not known about it, or you were replacing your computer often enough not to notice.
And before you go to the boiler-plate argument about little old ladies who don't know about that last sentence above, well they're the ones who can screw up OSX too, no different than fumbling with a microwave oven, not knowing how to use voicemail, forgetting the car keys, etc. It's a generational thing. Your parents and the Windows newb's in the 90's had issues. Now they're experienced. Now the problem is solved.
First, as I said, it wasn't the 90s, it was more recent. Windows didn't really have proper network support and browsing capabilities until late 1995 but malware wasn't really an issue for a few years (at least, not to the level of everyone needing an antivirus). However, Windows XP was horribly insecure and came on new computers until early 2007. This means, what I'd call the hayday of Windows malware was from ~1996-2007, which as you can see it mostly in the 2000s.
Second, it's foolish to think the problem is solved. It's not solved, companies like AVG are just a perpetual bandaid printing machine. It won't be solved until Microsoft actually begins to take security seriously, instead of just talking about it.
If you have to use Windows, use Windows. I have to use Windows for work, and it's fine. But if you use Windows, it's irresponsible to assume that taking 5 minutes to install AVG guarantees security. Little old ladies or experienced technology professionals alike need to know how vulnerable Windows is.
