How can I make my mom’s Windows PC bullet-proof?

I would like this question becomes a sort of newbie guide concerning computer's security behaviour...

few examples that come to my mind:

• don't open mail's attachments from an unknown sender
• use an alternative browser/os to avoid the most diffused dangers
• do the OS updates

Answer 1

I usually tell them the following:

• Enable WPA and MAC filtering on their home router. Additionally, change the default password and disable remote administration (not needed in most cases).
• Download and update a free malware and/or spyware scanner (MSE)
• Consider attachments from anyone potential threats because that person's system might be hijacked
• Use a keychain to secure their passwords (KeepassX) whenever possible. It's good to explain how to care for this secure password storage file and keep it backed up.
• Make regular backups of important data in at least two ways (storage media and dropbox)
• Regularly update the OS and Software they use. A tool like Secunia or AppFresh (For Mac) can usually make this a lot easier.
• Use a PDF reader that isn't from Adobe.
• Try to show them how to get software they need from better locations and how to do basic research on problems.
• Try explaining to them why they should pay attention to messages that are generated from the OS and software before simply trying to click their way out of it as fast as possible.
• Point them to resources on being protected against Identity theft.
• Give them a basic overview of what makes a good password and changing them every so often.

This is all I can think of off the top of my head. Hope it helps

Answer 2

• Don't install toolbars ever!
• Be careful where you watch movies online and where you play games.
• Don't download games unless you know they are safe.
• "Free" Screensavers are a major no-no.
• AVG Free as a minimum. Norton and McAfee are OK, but will slow down your computer, especially when scanning.
• Run CCleaner regularly. (Watch out for the "History" check box if you use your history.)
• Startup entries should be managed carefully. Use either CCleaner, or have a techie use msconfig.
• Don't ever touch msconfig yourself or you may destroy your windows installation. On second thought, maybe don't tell neophytes about powerful system tools. (Regedit, anyone?)

Answer 3

1. update all software used on the system
2. use virus/malware protection software, keep it up to date
3. use strong passwords, at least 10ish characters long, and add some special characters
4. each user should have their own account, don't share passwords or accounts
5. download files only from known good sources, in general only established companies... no random internet downloads
6. keep private information in an encrypted container (truecrypt is super easy to use)
7. don't give out personal information unless you trust the site you are on (think for a moment before just entering name, address, social security number and the such)
8. if a site has an expired security certificate think a moment before just accepting the expired/unsigned cert.
