    I’ve been getting notifications from windows defender saying it’s detected it and is removing it but it happens every day for a few weeks now and when I open it it shows that it hasn’t been removed like its waiting me to do it and I still don’t even know how it got on my computer since I haven’t installed anything for the last few months.
