I have been attacked by multiple viruses. My AV, Bit Defender has blocked them but has not gotten rid of them, after waiting 4 days for their help I decided to follow the steps here to remove them. I used SuperAV and found four infections, and removed them, but today the viruses came back. So I ran antiMalware and found 5( some of which might have be in quarantine. I next did a hijack log but I got a message saying "denied write access to Host file" hijack gave me instructions on how to resolve this but that didn't work. I suspect these viruses are still there. I could not cut and paste the hijack log but I did take a pic of it. I would appreciate any help .
Thank you
