Hi Forum folks. Please advise what is happening and how to correct: Frequently on my Vista system I will see a yellow balloon appear at the task bar telling me I need to update NOD32. It looks like an official MS Vista notifier. Also frequently when I close IE7 it crashes with the message "Error caused by NOD32 Antivirus Situation: No solution available". I have not installed NOD32 on my system and find no record of it in either my registry or Program Files folder. All comments welcome. Please help me understand what's happening and how to correct it. Thanks.
