How did you uninstall AVG ?
- Add Remove programs ?
- a generic third party removal tool ?
- did you uninstall with CCleaner, I can see it on your "Programs and Features" list ?
- if you did use CCleaner, did you run as Administrator ?
I would not run any generic driver updater at all.
- best to fix the shut down problem before adding anything else.
Just because AVG is not listed on the installed programs list does not mean it is clean removal.
- as i said in my previous post, if there are any residual files/settings they might be clashing with other AVs you have tried to unsuccessfully install.
What AVs did you try to install, and in what order ?
- from your OP you tried several, one on top of the other
- and to repeat ...
All care must be taken when installing AVs on a machine that has had another AV installed ( or I assume even a failed install)
- using Windows "Add Remove" is not good enough as there is a risk that remnants of the previous AV is still on the system, and might conflict with a later AV install (it happens)
- the default "uninstall.exe" files that come with AVs (in my experience) do not always thoroughly cleanup.
Best to see if the new AV vendor provides a link to a thorough uninstall tool by the first AV vendor
I would suggest you download each AVs official uninstall tool and run them in the order you tried to install them.
Doing emergency shut downs should not harm the PC
- have you backed up your data ?
Take a deep breath, stay calm and we will try and get through this one step at a time !
