IFR:
I too use PC-Cillin and have been very happy with it. I just checked the PC-Cillin site at
http://www.antivirus.com and found at least 4 references to the Snow White worm, it is just not listed as that in the encyclopedia under that name, here are a few of the aliases it can go by "Snow White, I-Worm.Hybris, W32/Hybris@M, Win32.Hybris.Gen, TROJ_HYBRIS.A, TROJ_HYBRIS.D, TROJ_HYBRIS.B, TROJ_HYBRIS.C, TROJ_HYBRIS.E, TROJ_HYBRIS.GEN, TROJ_HYBRIS.DLL, TROJ_HYBRIS.PX
I am using PC-Cillin 2000 with pattern file 882 is that the same as what you were using??
I also tried both McAfee and Norton and found both to be system hogs so I trashed them. I have been very happy with PC-Cillin and have used it since ver. 2 about 5 years ago and have never had it miss a virus yet (fingers crossed)
Cheers and good luck staying virus free.
