O4 - Global Startup: 802.11g Wireless Client Utility.lnk = ?
is a dead link, so it may be safely "fixed", but it really doesn't matter that much.
Anyway, your HJT log is now clean.
I asked, if your connection is wireless, because maybe there is something wrong with your wireless security, and someone is getting into your network.
Did you by any chance play with "port forwarding"?
