Peacomm diy removal

Hi sorry if Im asking what has already been asked I searched but couldnt find anything that related.

 

360 has identified two files as peacomm trojan and trojan horse and promptly quarantined them. I am unable to afford Norton removal service so diy it is for me.

I have done this before on a windows 98 system but never on vista.

I have looked thro the relative virus definition pages and checked the rregistry for the entrys it said should be removed . They are not there.

Im somewhat confused as to how such a common threat entered the system since it has been running nortons since new and all protections have been on . I discovered both threats today after a full scan but to my dismay one has been lurking for a month or two. whilst nortons quarintined at some point probably after a scheduled scan there was not desktop notification of it.

 

Question..

Do I really have a virus or just an unactivated file that carries it now safe because its quarantined.

 

Any recommendations would be appreciated
