It's amazing you can still be productive with Windows 95 in 2019. It shows you how great it was. Imagine getting anything done with Mac OS 7.6, which was current in 1995.

We simply didn't know what dangers lie in connected computers back then, so it's no wonder it would be vulnerable to attack. Still, you'd think the sheer age of it would protect it (who's still attacking Windows 95?) and it probably did keep them safe for some time.
