Query: Just When I Thought I Had Found a Perfect Virus Protection

I bought one for my mother too-She runs Windows ME- It will not install on ME and TrendMicro does not support it. I had to purchase a download from TrendMicro and we all know how that goes--Anyway the one I bought for myself-Windows XP, installed easily but when you try to manually scan, there is a problem--- I have had PC Cillin for 4 years and alas I feel that this will be my last year-- Too bad to, I really enjoyed the ease and simplicity of prior years
