If you use Window XP or Windows Vista, Microsoft has a tool that could be useful to some people. It’s meant more for shared computers, or for any PC that’s at greater risk of infection.
What it does is fairly simple. Every time you reboot the PC, Steady State will restore it to how it was before. So no matter how many viruses, spyware and adware you end up accidentally installing. it becomes fresh and anew.
You need to install it and set it up correctly, and for most people it might be a good idea to get some advice from someone who’s IT savvy, just to make sure you take full advantage of this great tool.
Best of all is that it’s free, as long as you have a genuine Windows XP or Vista license.
While you should still be responsible with how you use a computer, what you download and which web sites you visit, this tool is great tool for certain people.
