Hello Paul
Before to take drastic solution
- Formatting
Could you install MacAffe? Or Norton? Avast?
Be sure to install each one, do a scan and uninstall and install the next one
Once done check the Google Chrome … if it seems correct install the adblock extensions
Btw… i did say get rid of windows and replace it with linux mint!, I told him that with his last computer a few months back when his old machine was infected, but his answer was buy a new computer, which he did buy second hand, that was also infected at purchase, so he took it back to the shop and bought new… some never learn !
If he does not use the following:
- MS Office 365
- Adobe PDF
I think is possible go to Linux in peace but
In other post in this network was discussed about MS Office for Linux. One of the best suggestions was use MS Office 365 through Web.
Finally if is mandatory use Windows: if the Windows 11 license is original reinstall it, get by command the license. Is possible get the iso file from Microsoft itself. For more details be sure to read the following solution:
It should work for W11 too
My 2 cents
To Admin if a special section/category in Its Foss network can be created for Windows would be nice, because even if we are Linux users, we use Windows by either a direct use (member of our family, friend, co-worker) or indirectly (Virtual Machine)
