It's been 5 days and I cannot open facebook from my laptop. Internet explorer says "your current security settings do not allow this file to be downloaded". Firefox and chrome doesn't load the sign in page fully with no pictures, videos and logos . Even while signing in to yahoo answers I faced problems because chrome warned me that this site does not have a trustworthy certificate. I installed Kaspersky 2012 a few days ago. Is it blocking all these sites..or something wrong with my net connection and laptop? what must I do? Please help.
