I put the AVG scanner on this evening, as usual.  Right away I received several threats,
then got a message form Windows saying it had to shut down right away and reboot. This happened about 3 times.   There was a message explaining the problem , but I did not have time to write it down. Has this happened to anyone else?  I have never had this happen before, I have never had any problem with AVG before either.
