now disabling messenger service is not so good advice. It would be like
trying to hide "result" of some problem and not dealing problem itself.
Better install firewall and get it configred properly, some free software
firewall should do the job. www.zonelabs.com has zonealarm but there are
numerous others also.
besides spybot, ad-aware and installing firewall, get proper virus killer if
you do not have one.
