I have had no problems and have had them for over 5 years.
Was very easy to install. Will do this agian next year.
I use this program to keep viruses off of my computer. I have been using the program for three years on my main computer without any problems. I do see to have trouble when I use this program on my HP Laptop, I have had my laptop repaired numerous times for viruses while having Webroot as my main antivirus program. Overall, worth the money.
