Strange extension/object " _.!%#@$ " seen during a scan with Bit defender Mobile.. what could be?

A quick check on the internet suggests that it might be a malicious file, though this is just an assumption.

Here’s an alternative approach you can try:

Download the VirusTotal app ( https://play.google.com/store/apps/details?id=com.funnycat.virustotal&hl=en_IN&pli=1 ) for Android from the Google Play Store and scan your entire device with it. This will help you identify if any particular file is malicious by testing it against the majority of antimalware vendors.

If a detection is found by well-known antimalware vendors, you can share the file's hash here, and it will be forwarded to the Bitdefender malware research team for further analysis. However, if no detections are reported, you might consider asking your question in the Android Community Forum ( https://support.google.com/android/community?hl=en ) for additional insights.
