I purchased a two-year subscription from Emsisoft. I had problems from the start. Computer would lock up, I couldn't use another program while it was downloading, etc. Then I had trouble with my printer so I called my printer company and they did an off-line evaluation of my computer and found that Emsisoft was like a virus. I had it removed and everything has worked great. I have asked for a refund of the second year that I paid for but because the request didn't happen within the original first 30 days they will not refund second year. I did not ask for a refund of this year but I'm only into a couple months of the first year and there isn't any reason they can't refund the second year. They just don't want to. Don't buy is my opinion.
