I installed the free trial of AVG Anti Track which caused my lap top to freeze and prevent emails from friends and after I uninstalled it my lap top returned to normal I have now received an email informing me they will charge me and I can find no option which would let me cancel the product as it is awful. How can I stop them from charging me? and opt out.
