Keep in mind that the biggest threat to your system is you. If you click OK and allow every request without scrutiny then your chances of infection increase drastically. I suggest everyone use a router even if you have only one computer. I wouldn’t be without one.

You can access Windows System Restore right here from the same System Properties. Click on the System Protection tab/ System Restore /Restore Files and Settings/Next/Pick a Date and follow the prompts. This is also the same area to create a new restore point or to reduce the amount of space alloted to system restore or even turn off System Restore.
Take the time to familiarize yourself with this area and you will feel much more confident in your ability to use your computer.
