Hello, I got this virus warning 4 times yesterday from Windows Defender.
and each time I deleted the virus, the file. I also do virus scan with malwarebytes and hitmanpro and they found nothing. and i delete all cookies and opera but every time I reinstall Opera I still get this warning. I just went to Netflix and Instagram sites. What is this? Help me please.

@leocg yes i know but its coming from instagram, i check the file its a picture from instagram explore... actually i scanned that file in virustotal and it says it's clean. but I don't understand why Windows Defender is doing this. Maybe its just a false positive... I just went to Netflix and Instagram bla bla nothing weird web page thats why its annoying... Should i format my pc?

Sounds like a false positive. However, do you have any extensions installed that didn't come from https://addons.opera.com/en/ or https://chrome.google.com/webstore/category/extensions? Some users installed 3rd-party extensions that insert spyware/malware-related stuff in page content.

At https://www.microsoft.com/en-us/wdsi/filesubmission you can submit a report, upload the file and say that Windows Defender is incorrectly detecting it.

@burnout426 I already deleted the files, if it happens again I will do it but i hope not
most of my friends don't use windows defender because of this annoying false positive... but it still makes people paranoid so...
