-if your browser directs you to anywhere but where you wanted to go...you have an add-ware installed. It gets' worst.
Add-ware: is a symptom. That means that there is a hidden program in your computer that puts up another program. As soon as you delete the symptom the hidden program re-install's it for you. The only way to fix it is to do a system restore .... a month or two back. It will not delete your docs or pictures , only programs ...which you will reinstal by hand. Very good idea to backup everything to something. Hard drive is good.
if you can't roll back, do a factory backup. It may take about 30 to 45 min to do it but you will have a brand new computer...you have to put your stuff back. and no, it will not keep your documents or pictures. You have to save them before you do a factory restore.
you can't win this ad-ware battle.
