PS; some of those free programs want to install Internet toolbars..
NEVER - EVER install those.....
They are nice, they are nice, but they all are PC garbage.

Those things can get any PC on its knees.

If you have some of these toolbars installed, as Bing, or Google, or Ask, or yoohaaa? 
Uninstall them, an throw them away as far as ya can.. And then go after them and throw them even further away.

Attention;
Your PC might kiss you for doing so.

Always keep in mind, that everything on you PC will cost time:
Or it gets loaded in memory, or it runs in the background, or it is just anoter file for your virus scanner to look at: each and every time.. it runs.

It is like cleaning the house, once a week :-)
