Query: Garbage -- The worst software I have ever purchased

Save yourself a lot of headaches and look for other software packages to secure your computer. BlackICE is the worst software I have ever purchased: buggy, horrible support, unusable. I have tried similar packages and this one ranks at the bottom of the list. The system crashes continually and I usually needed to re-install at a minimum of once per week. I did some checking after the fact and found others who had similar experiences; unfortunatly I didn't check before I bought the software in the first place. Save your money and find something else.
