Windows 10: My Windows Security is gone !!!!

Hi guys, I'm facing some unexpected behavior in my windows 10 that my threat my windows overall security, so yesterday i downloaded a software called system mechanic because my ram usage was always high so my friends recommended me this software so after downloading it , i opened it and it showed me some weird message saying that Windows 10 has a critical uptade and that it needs to restart , i tried to cancel this warning message and proceed to the software but I was unable so i decided to go on and restart my windows 10 through this app and this took me to a blue screen saying that my windows is updating it took a long time so i shut off my laptop and powered it back on then i was surprised to find that avast antivirus was uninstalled without even me knowing and that windows defender and windows uptade were lost and never found, I tried all possible solutions in the web, I went to services.msc and I didn't find windows defender so i went to this forum https://www.tenforums.com/tutorials/57567-restore-default-services-windows-10-a.html and i found that i can download all services missing so i downloaded windows defender service and windows uptade service, I started the windows uptade service and it works now and when i tried to start windows defender service from services.msc it showed me this weird message:





And after hours of searching nothing ever works, i even went to registry editor and tried to fix false values from youtube but nothing works, so when i gave up I decided to make a system restore and after 30 minutes of restoring my pc powered on and system restore showed me some other weird message telling me that the process has failed because some antivirus is
interfering and I can guarantee you guys 100 % that there is no antivirus in my pc now so how come , so i suspected that this might be some kind of new virus trick that fakes its identity and appear as if it was an antivirus, so i opened my task manager to search for any wierd processes but found nothing suspicious but when i opened the startup tab in task manager i found this weird .exe called avlauncher in my startup :






people on the internet say its related to avast antivirus so this was really weird because avast does not exist in my pc anymore so i thought it might be a virus that uses avast name to trick users, anyways when i tried to disable it nothing ever happens, please HELP!!!!!!! I'm tired of searching for long hours with no help

Why did the startup window get cleared?

I didn't missed any step, the list was gone and gone , even after using lot of programs the programs were not listed in that list.

That made me so facepalm. Some people have absolutely no clue. I hope they don't take you for granted with all this you're doing for them.

SonicWall is a good security product, so Mindweaver's suggestion sounds like a good one and should make for a rather bigger baby step. Let's hope they take it.
