Hi, today i bought a Win10 key, and couldn’t activate it. Months ago i noticed that my cmd crashed when i launched it, i found out that creating another user account made it work, i found it very weird but didn’t think much of it. Later i noticed that my Windows Defender is completely blank, when i go to windows update & security and go to Windows Security, the page is completely blank. Today i found out when searching Windows Forums for a fix to the key problem that my “WinDef” was hijacked, probably by some malware. I scanned my pc with AdwCleaner and ESET scanner and detected infections. I also plan to do an in-place upgrade repair with my Windows. Big thanks to anyone that helps!
