Lenovo Computer running Windows 8.1. Received a Message that I had a Trojan Virus and to call an 800 number. Called and decided that I thought they were the one who gave me the virus. Called Lenovo Premium Support and was advised that I could purchase Premium Support and they could resolve my problem. Leading up to this problem I had been getting numerous "Script Error" pop ups. I have spent the last week talking to Lenovo Premium Support. They have done two Computer Refreshes and one Computer Restart. I got another "Script Error" pop-up this evening. These pop-ups came at random, I see no pattern to them. Any ideas?
