I had Installed Verizons DSL software on 1 of my machines. Anyway I had noticed activity leading me to suspect a spyware/Trojan infection. I downloaded a copy of Spybot S&D, updated it and ran it. It would get just a short way thru the scan and abort. (Scan aborted by user) But I didnt abort it. This made me very suspicious. I opened the task manager and looked at the currently running Proceses. I noticed 3 that I had no knowledge of. MotiveBrowser.exe, VzOpenUIServer.exe, and MotiveSB.exe. I did a search and found a Motive directory in my program files directory. Next I shut down all 3 processes by right clicking and clicking End Process tree. That killed all 3 processes. I then tried running Spybot. No problems at this point.
Anyway I had traced all these programs to the Verizon Installation so I opened Control panel--> Add remove Programs and removed all of it. No more problems at this point. Spybot functions fine. I did a Hyjackthis scan and it looks clean.
I guess the point of this is to not install any software that you don't need. At the time I didn't realise, I didn't need it.
