In my day, all this were trees...
I remember, in the olden days, when Peter Norton produced some of the best Utilities for the PC. He called them his "Norton Utilities" and many is the time I found that something wasn't quite right with a PC I was using, and was able to find at least one way in NU to fix it..
This was in the late 80s, BTW, well before the likes of Windows poked their noses into the scene, and there was a 1001 ways in DOS that someone even slightly inquisitive could totally bugger their file(s). Yep, I did that, a few times.
Anyhow, I digress.
Eventually, I moved on to Windows, and wished that something as powerful as NU for DOS appeared for Windows. It did. Symantec had (in the mean time) bought out Peter Norton and released a version of Norton Utilities for Windows 95. Eagerly, I installed a legit copy on to my copy of 95. Fired up Norton. It said I had one disk drive. I thought there must be some mistake, I had two before I installed Norton, so I restarted the PC. Sure enough, both BIOS and Windows would only detect one HDD. I had lost a lot of data.
I never used Norton Utilities again.
A few years later, I was looking to purchase an AV program for my newly acquired copy of Vista. At the time, Norton AV was the only one advertised as compatible, so I bought a copy.
What a pile of shit. To get it to work with Vista, I had to install the CD copy. Ignore the warnings about incompatibility. Reboot when prompted. Then log in again, download an update for "Live Update", reboot, log in, run "Live Update", install any udates it suggested, reboot, log in and finally use the machine. And I'm not convinced it was protecting the machine well..
