The May 2020 Update came with multiple security features, including Windows Hello in safe mode. Windows Defender itself got enhancements in areas such as firmware protection to prevent bad actors from compromising devices. Notably, Microsoft updated Windows Defender with the ability to sniff out potentially unwanted programs (PUPs).

Windows Defender flags the same PUP multiple times

When a PC scan identifies and neutralizes a PUP threat, you don’t expect to encounter the same PUP in future scans. But, according to Microsoft, its Windows security tool keeps highlighting the same blocked PUP as a threat many times over. As you’d expect, other scanners don’t detect the same threat on a PC after it’s been removed. Microsoft recently revealed the source of the problem: Windows Defender looks into its own protection history, which is where it keeps information about all detected and blocked threats. That’s how it keeps finding PUPs it has already resolved in previous scans. It seems that Microsoft isn’t ready to start quarantining the PUPs. Until then, you can configure Windows Defender not to search for PUPs in Protection History. That setting will stop the multiple false alarms. Microsoft Edge was also updated with the ability to block potentially unwanted apps (PUA). Is the Windows security tool flagging the same PUP multiple times on your PC even after neutralizing the threat? You can let us know via the comments section below.
