Hello John. at the end of that trojan horse it shows a tag “.Gen” this means that this is a generic detection. The best thing to do would be to submit that file to www.virustotal.com and find out if it’s infected or if it’s a false positive.
I cannot seem to get rid of the thing… AVG says that it cannot be removed, and then says that if I elect to move it that i might end up with an operating system that does not work properly.
Autoruns in the main harddisk can be safely deleted. A harddisk doesn’t need an autorun to boot to windows. The warning it says is because if the autorun was like in a USB for example and you delete the autorun. The file that was suposed to execute as soon as the usb is connected won’t work automatically. You’ll have to open the file yourself.
As for the infections you seem to have. Download superantispyware and Malwarebytes and do a scan. You should be clean afterwards. If not, then inform what happened
