Fernando can't download Windows XP Service Pack 3. Leo says that's because they've stopped supporting XP. Can he get it elsewhere? Leo says not to go anywhere but Microsoft to get updates. It's just not safe, especially from Softonic. They usually add stuff that will install other things he doesn't want. But really, he's no less secure without it if he just follows the following guidelines:
1. Stop using XP 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.
3. Don't click on links in email.
4. Only get your software from original vendors.
5. Keep your anti virus software up to date.
6. Stop using Java
7. Use a password vault like LastPass
8. Turn on second factor authentication
Leo also thinks it's time for Linux. Why not move to open source software? There are versions of Ubuntu designed for older computers. XuBuntu and Lubuntu are good ones. Antergos and Debian are also good ones.
