Bitdefender Antivirus Plus detected trojan Gen.Variant.Tedy.373140

Hi,

I am new paid user of BD antivirus plus paid.

Please help as BD detected Tedy trojan when I scanned as external HDD. Please move post if this is not the relevant section.

System Details: Win 11 with latest Sep 25 updates installed, BD version: BD antivirus plus 26.0.18.75, BD agent: 27.1.1.14

Standard user account.

Problem:

1. System fresh install couple of days ago with not much use.
2. External HDD bitdefender scan detected trojan Tedy in one of the folder and was quarantine immediately
3. Soon after BD quarantined these files:
4. bdagent.exe, mspaint.exe, onedrivesetup.exe, firefox.exe, agent_launcher.exe, photos.exe, bravebrowser.exe seccentre.exe and bunch of registry entries quarantined
5. Virus total is not so conclusive : https://www.virustotal.com/gui/file/f5e6ea681a20643f031893713ba620c99f3608ae74862ed79838cb2dc6a3cc61?nocache=1

Queries:

1. NOTE1: None of the Windows apps including bdagent.exe was fine and not detected as issues
2. NOTE2: As soon as BD detected trojan and quarantined the file, many Windows registry entries, apps like Photos, mspain.exe, seccentre.exe etc were quarantined.
3. Did BD cause the trojan to test run while analysing?
4. Why did the windows apps like photos.exe, mspaint.exe, onedrivesetup.exe and also seccentre.exe (I believe security centre !!) got flagged and quarantined?
5. If we check, there is a sneaky entry agent_launcher.exe entry quarantined from Temp folder.
6. Should I reinstall Windows as I am not so confident on using the system after this incident.

[ I have not yet rebooted the system as I am afraid many windows services will start failing].

I am not so technical person, I am confused now why did bdagent.exe itself got quarantined for Program files folder. Please note this all started happening as soon as BD quarantined the detected trojan file.

Screenshots attached.
