Richard is having issues connecting to the Internet after cleaning out his computer. It's loaded with Windows XP and he can't download any browsers. Leo says that Microsoft stopped updating Windows XP and if he can't install something like Chrome, then there's a problem that worries Leo. He says he can go onto Google, but can't run Chrome, only Internet Explorer. Leo says that he can use XP online, but only if he's careful. Here are steps to protect yourself since Microsoft has stopped supporting XP:
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
Also, if Richard is getting certificate issues, then chances are, the date is off and that's broken the certificates. So that means the motherboard battery is dead. So he should change that out and make sure he has the right date and he should be able to go online with no problem.
