HP XP home edition All up to date

Trend Micro detected DIALER_LINKDOTNET and removed it. But I noticed that every time I run an application it is entered automatically in ZoneAlarm, that includes the control panel and security center, among others. I had to block every entry manually. DIALER_LINKDOTNET comes back and Trend Micro removes again.

I tried to look up what I could do to prevent this DIALER from recurring. Nothing found so far. Anybody has any information about this spyware?
