Installation without problem. First long analysis (3:15) detected 50 threats ignored by former paid software. Unfortunately, KIS has not been able to eliminate them. On January 14, contacted technical support. On January 16, no response, a complaint to the manager. On January 20, finally an answer. I have to return a report from a utility to download. On 21 January, receiving a standard procedure to apply. It does not correspond completely to my case. I ask additional questions the same day. On January 23, scathing response support: "We do not intend to explain the manipulations If you can not, please get assistance by a relative We will not respond to your case..." Waiting nine days to receive such a response is somewhat shocking !! I have already requested the support of my former paid software. Never disappointed with the speed and quality of their performance. KIS is definitely a good product, but the support is again !!!
