It would make life easier if you told us what Trojan it is or what i
exactly happening
The only thing is to follow the advice given by Mac since no clues ar
give
If you are using an Anti Virus Programme then I would visit their we
site and if that dosn't help I would consider an alternative AV. Bu
having said that you will, I think you'll find that some AV will b
good at some and bad at others
One good thing is to use something likle Privacy Gaurdian and let i
run before you shut-down, only takes a few seconds. That way they ar
not lurking in RAM waiting for you to shut down and being written t
the hard drive where it'll make itself at home.
Some Trojans come in two parts...first the "downloader"
this is the active part where it sit's and waits doing no damage a
all...until you visit an infected site upon which anything can happe
and can be controlled for a specific task
