So what happens if you don’t install updates and surf safely?

The one year experiment is done!  A year of safe thoughtful surfing, no anti-virus and after scanning for malware, spyware and viruses – zero.   Its now time for updates and anti-virus.   The key to safety on the internet starts at the keyboard.

Is it smart to do?  No.  No one should ignore updates to any operating system or updates to applications on the operating system regardless of the vendor.  Apple, Linux and Microsoft along with any software written will need updates for vulnerabilities.   This experiment was checking user safety.

With vulnerabilities of remote access and tons of others that are often found, it is critical that you get your updates.
