Avast keeps showing pop-up regarding a trojan JS:Miner-AV[Tr]
« on: October 09, 2019, 02:24:15 PM »
Hi,

I have an Avast Pro Antivirus paid version installed on my Windows 10.  I keep getting pop-up regarding a threat. Please see the attached image. It just appears randomly.

I've cleared my browser data, temporary files. My windows was updated recently. All my software including chrome are updated. Based on google search, I did factory reset of my router.

Can somebody help me.

Thanks.

Update - I've updated avast to Premium security, but issue still persists. Ran Wi-fi inspector but that looks fine too.

Does popup appear when Chrome is closed?

No it appears randomly even when no browsers are running. But I found something interesting. Issue only exists when I am connected to a particular WiFi. When I change my connection to a different WiFi, there seems to be no problem at all.

Problematic WiFi has Netgear JNR1010 router and has latest firmware.

Can you factory reset that router?

I already tried resetting the router and also checked all the router config settings, which could be important for browser security.

Is there anything related to DNS in router settings?

If problem persist even after factory reseting router settings request for warranty replacement if possible.
