After not being able to get my purchased Restoro key to work I called the provided toll free number. The agent I spoke with happily used my key for me and began to scan my computer. I was shown screenshots of broken registry files and a trojan. Instead of Restoro fixing these problems I was referred to a 3rd party who tried to extort $600 out of me for a year plan for remote maintenance. I finally agreed to a one time purchase of $100 remote help. This person spent about an hour looking at optimization and "removing" a virus that I'm still not sure was ever there. A month later my computer still doesn't work correctly and I had to use Malwarebyte to remove Restoro. It's garbage. Do NOT use this service.
