Debbie also has an old XP computer and wants to know if she can install Linux on it. Leo says that Debbie can, but she can also run on XP if she uses these steps:
1. Stop using Windows as an administrator. Use it as a limited user instead. Add an account as an administrator and then demote your existing account to limited user. This will stop over 90% of all the exploits out there.
2. Stop using Internet Explorer. Go with Google Chrome. It's free and far more secure. You also have to be sure it's up to date as well.
3. Don't click on links in email.
4. Only get your software from original vendors. Update Flash, Adobe Reader, etc. as well.
5. Keep your anti virus software up to date.
6. Stop using Java, you probably don't need it. But if you specifically do, make sure it's updated as well.
7. Use a password manager like LastPass to generate long, random passwords and keep track of them. And you only need to remember one password, the last pass password!
If she does these things, she'll be fine moving forward.
If she runs Linux, will she be able to print? Leo says in all likelihood yes. She'll just have to find the drivers for it. She can Google the model of the printer and "Ubuntu" and Debbie should find what she needs. But it's not for the faint of heart. Linux is an enthusiast product and the casual user may end up pulling their hair out.
