I have AVG free 2016 installed on my computer - have been using avg free for years with no major issues before. Lately, the scanning will not proceed past 1%, even after hours. I have tried repairing and uninstalling, which have both failed. I managed last night to have a repair go through successfully but this morning it is back to 1% scanning again. I have windows 10. A message comes up on the failed to repair screen which says
Description: Service%NAME% failed to progress during start up at checpoint % CHECK-POINT (wait hint % WAIT-HINT%ms) in % WAIT-TIME% ms
Erorr code: 0xE0010032
Today I had nothing else open at the time while AVG was supposed to be working.
