8/22-8/23/2026 screen tured black and 2 days ago important data file auto disappeared, chat with AI

[why my notebook screen suddenly turned black twice ?] 

[came back on its own with i click KB keys. before it turned black i deleted the fraud email that pretended Geek Squad, Inc sent bill $288.81 for ordered GuardianMatrix Elite, quantity 4.]

[it is 1st time happened to me and right after i google searched whether it is fraud email then followed suggestion to delete the email. and it happened twice.]

[thanks. and i knew defender would showing 0 threats. myself suffering file explorer, data files, bank website frequently seemed switch to different versions. and no way to prove it that the whole MS updated made it impossible to identify the real problem is. any way thank you for help me calm down]

[that is the key that i didnt insatll onedrive as i knew no good to me but lost new/modified data files by auto SYNC problem. the screenshots works if small area not the longer screen (bank website) the worst download screenshots files would be auto disappeared too when file explorer daily auto switched versions]

[didnt see green checkmark icon , already turned off remembering preferences and my apps.]        -- a small green checkmark overlay on a file or folder icon means the item is fully synced to cloud storage like OneDrive.

[already did 1 and 2 . one of data file was auto disappeared recently and i have been suspect MS seems set a counter if the data file daily opened or sometimes modified then auto disappeared happened.]

--AI answeared it was reverse. but i did suffered file on demands and frequently used data files disappeared serious problems.

[i didnt install any companies anti-virus except MS defender however one of app seemed binded with McAfee that can found in device manager shows McAfeeswitch , McAfeeintegrationDriver Device, should i uninstall it, and what driver embeded McAfee ?]

--i used device manager to verify Disk drives is NVMe 高速盘 or not then noticed [McAfeeswitch , McAfeeintegrationDrive] in the beginning thought related to  Lenovo Vantage or Lenovo Service Bridge but turned out not related.

[when i click [device manager shows McAfeeswitch , McAfeeintegrationDriver Device] properties, showed 4/22/2026 that remember my notebook got trouble april-may, 2026 . when i clicked view all events then redirect to [ event Viewer , windows defender , operational] listing all MS defender running dates. is it normal or suspecious ?]

--AI : Not suspicious.

[i did see windows update history : 4/22 windows 11, version 25H2 (repair version) installed. so MS updated caused and installed [McAfeeintegrationDriver Device] , correct ?]  AI: Yes.

[i click your link [ McAfee Consumer Product Removal (MCPR) Tool] redirect to [https://www.mcafee.com/support/s/article/000001616?language=en_US] which shows [Windows 11: Select Start Start icon for Windows 10, 8.1, and 8 > All apps and search for McAfee in the list shown.] but it is not in windows apps listing . should i direct thru Device Manager to uninstall it ?]

AI: Yes.

Now, wait to see whether file explorer switch versions again.

now my questions is if it caused bank website switched versions by McAfeeswitch , McAfeeintegrationDriver, then who stole our money from bank, investment old versions ? i told spouse this year our investment stocks suddenly showed 5 in stead been 4 (for quite long while) but it back to 4, also felt i did transfer from checking to savivings at least 4 times in this year but only showed 2. i am going to review old statements to find out.
