am getting blocked web sites?

[lanshark]

first thing I would do in any case od unexpected computer behavior is run a malware check.
download malwarebytes antimalware its free and in my opinion the best.
http://www.malwarebytes.org/products/malwarebytes_free/

next delete all your history, and cache files from your browser.
if you don't know how google it.

if it still doesn't work reboot your internet modem and router. my router goes funky from time to time and blocks random pages that I go to allot.

good luck
