Query: PC-cillin...don't waste your money

Once again I try and use a program which offers more for less money than Norton.....and I learn that I have again thrown away my money.PC-cillin "looks" like a good deal but when it comes to actually installing the program---flat out...it doesn't work. I have tried over the past week to register this product and to obtain updates...all to no avail. I have entered the serial number of the program and my email identity yet Trend Micro tells me that these are not legitimate. I have never had success with McAfee and now I can add Trend Micro to the list. Stick with Norton.....it is expensive but at least it works.
