Recently I renewed my subscription which also allowed me to get another norton product that I have never used before, Norton utilities. After using Norton utilities my computer started telling me that my windows was not genuine, I had no restore points, and my norton internet security will not do a full scan because it just crashes as soon as I try to begin the scan. I have tried Norton RnR, NPE, and a bunch of other scans such as search and destroy and malwarebytes... this computer just seems wrecked. What can I do?
