Howdy,
My pc operation system is XP.
My pc runs fine but as of today (never before) each time I try to run an AVG scan it ends-up going to blue screen fatal error C000021a.
PS: I've run several updates and thei works fine - just can't scan.
Any suggestions

Mark

I have 5 computers running Windows XP Pro 32-bit, and they ALL reboot about 20% into the AVG Internet Security 2015 scan.  I know it's not one computer, since they all do it every time.

I'm having pretty much this same problem, using AVG Free 2015 on Windows XP Pro SP3 32-bit. Some extra info: I was running AVG Free 9.0 this morning (decided to upgrade to attempt a fix). The older version did not die to a blue screen, but it did tell me my machine was infected with 37 instances of "Trojan horse Agent5.AETS" that it couldn't ("Object is inaccessible"). I've installed no new programs since the last clear scan, so I'm inclined to think this is some sort of false-positive. Malwarebytes shows no infections.
