I use the ZoneAlarm firewall, which recently flagged up an application called "WLL LoginProxy.exe" which was evidently trying to contact the internet. Not knowing what it was I denied it access and nothing untoward followed. Naturally I wondered what it was, so I put it into an internet search engine and was surprised to find hardly anything about it - usually these things get quite a number of responses. All I got was one other person on another forum, asking a similar question about the same thing, but no answers were forthcoming. I also searched my hard disks, but nothing like it seems to be there. Has anyone using this forum heard of it, and should I be concerned?
I have, incidentally, also occasionally had ZoneAlarm flag up "Software Application" in a similar way, but that one looks even harder to pin down. As usual, I have always denied it access.

Found a definition of WLL as Wireless Local Loop.
If you are running a wireless network, possibly someone trying to log on to use your Internet access?

Thanks for the suggestion. However, I am not using a wireless network, so it remains a mystery, but at least if that's what it is, it doesn't sound like anything to be concerned about. Thanks again.
