on the contrary, linux does have virus problems dating back to the late 1990's and more recently better prepared software have targeted various linux oses. comparing windows and linux in the same sentence is like comparing diesel to gas engines. each has many of the same parts but operate differently. and if you lost data due to a crash then you failed to backup that data like you should have done. and linux is not as easy to use as windows.
Totally wrong. I've never had any issue with a virus on Linux, regardless what distribution it was. Plus I never backed up anything on Linux until recently, and never lost anything either. If I mistakenly delete something now, it's on a USB and my other computer anyway but that's never happened. And I don't save (backup) for that reason, but simply if I want to transfer it elsewhere.
Backing up on windows doesn't help anyone when the computer won't work anymore, or when you have to buy yet another version of windows (which I've never done) to get it to work again. I've had windows computers that crashed and didn't work at all anymore with windows, put Linux on them and they worked fine from then on. The only intelligent solution is to never use a crappy operating system like microsoft windows, and now the same guy designs vaccinations for people.
Some friends of mine still use windows, and I've fixed their wonky windows setups for them a number of times including turning off updates, but soon their computers are completely screwed up again because that's how windows is designed to operate. It comes with bloatware and malware by design, and is designed so you can't ever get rid of it all. Plus turn off updates, and it still keeps updating and screwing things up.
Honestly, the windows OS has kept getting worse and worse, instead of better and better like Linux.
As to being easier to use, there is no comparison. Linux is much easier to use than windows and it's also much faster.
Besides that Linux is free and the programs are free. You can download any version, or get it from Ebay on a flash drive or disk.
