Earlier this week I started to receive this error message. Every time I start up the Norton screen pops up showing a 5013 Error. In addition to this error, I started getting blocked Trojan.Gen2 messages and backdoor blockings. They say no action needed, threats blocked. But I get these every 5 minutes or so. I have had several "blue screen" crashes in the past week. I have no idea what to do.... Do I have a virus or is something else happening. Any suggestions? Thanks.. SJH
