Employee installs multiple security softwares

Hi again.

I'm sorry I haven't been around to help. (I'm not an expert I'm afraid.)

I have a computer with multiple security products installed, and I want just the one that I've paid for which is Fix-It Pro. I have tried to uninstall as many of the others I could find but a lot of them seem to leave remnants and I am now stuck.

I have tried to download appremover to see if it could find anything and am prevented by something claiming it has a virus and stops the download. Attempt to download dds results in the same. Attempt to download GMER also results in virus found and download prevented...

The last issue that I've somewhat resolved is no network/internet connection due to what seems to be OnlineArmor remnants. It still lists three items in device manager that I can't seem to remove/delete. (One of the uninstalls must have triggered a setting to always start in Safe Mode which was a real pain to figure out.)

Things I've seen around in the registry are McAfee, AVG, and Norton to name what I can remember.

Please advise, and thank you for reading!
