I had the same trojan (well 3 entries really) and the only way I was able to get to it was to use System Restore.
What happened was when visiting an external link (i.e. not the PCA forum) my PC crashed and I couldn't get online again and after running PestPatrol this couldn't delete them as I had an 'access is denied' error.
There was also reference to a Kernel32/system file as explained at click here
I also noticed that while trying to log on to my ISP the program kept freezing with the error 'The program is not responding'.
