Sarath, Thanks for info. i would like to know if its AVG, Windos10 or both. Need advice on reversing procedure or a resolution. As at present it looks like a scam waiting for A RANSOM DEMAND.. I thought my sub. was paying to avoid this situation. I think an update on situation today from AVG  is necessary.
