I was infected with...I'm not sure but System Defender was part of it.
Whatever it was, it infected AVGfree, my google toolbar, google redirect to google.eu or something, wouldn't let me go to the AVG website (kept redirecting me), yada.
Also wouldn't let me update malwarebytes.
AVG reported Trojan Horse Agent_r.OT but wouldn't fix it. There errors were in [memory], or so it said.
I downloaded Combofix and it fixed it!
One thing though, Combofix requires no other software be active but I couldn't deactivate System Defender. When I ran Combofix, the pop-ups told me to deactivate but did not give me the option of cancelling combobox. I clicked the X but it ran anyway.
Anyway, I'm fixed. Thanks.
