Hello, I work on people's pcs from my place of employment, friends and neighbors often. I have set interested parties up with Nod32 trail edition whenever they express interest in what I recommend. I have in front of me a pc that I installed such on last night. The trail version updated, and I started the full scan and went to bed. Before leaving, I saw it pick up one object. When I got up the next morning, the laptop was shutdown. on startup, the program said Expired. I did put my email addy into the trail request, an address that had been used for another pc's trail version before. Question: did the used address cause this or a virus?
