Friend asked me about a file coming up in Norton Internet Security as trying to access the internet. I'm pretty sure it was oiu1.exe NIS defaults to block and I've ticked the box for always use this action but it still comes back. I've done a google search but cannot find anything remotely related to a virus/dialer/trojan etc. I did a search on her computer for the oiu1.exe file but that didn't find anything either. I also couldn't find anything on the Norton support site related to it. Mind you, if you've ever had to search the Norton support site you'll understand my giving up rather quickly. I'm sorry I don't have any specs on her system - don't think it's essential for this query anyway. Thanks - any help appreciated.
