I recently wanted to scan my pc, but i saw that my windows defender is blank because my defender is corrupted, when i try to search it in google about my problem i saw that the only way to fix it is by reinstalling my windows 10. So i would like to ask if it is okay to leave my windows corrupted, or just buy an antivirus for me not to reinstall my windows again because my internet connection is really slow these days.
I know that there are some IT people here in this forum, that is why i would like to ask about it.
I don't think that Windows defender provides good security to your system.
There are many more antiviruses that can keep you safe.
However, it is good not to keep it like that and broken as it will be a window open for incoming malware.
