TrojanDownloader:JS/Jesdow.B!url

[REDACTED]

I have the free version of Avast and it did not find the subject Trojan. I ran it twice and all came up clean. I also ran Malwarebytes AdwCleaner and it did not find this either.

Windows Defender quick scan did not find it but the Advanced scan did.

I am wondering why Avast didn't find it because that is my primary Antivirus Program? The program is automatically updated.

No security program have 100% detection or zero false positives

Did you consider that Windows Defender may be the one that is wrong?

anyway, you give no info
-what files was detected
-at what location ... full file path   (from detection name it may be a mail attachment ?)
-have you tested detected file at www.virustotal.com ... post link to scan result

I also ran Malwarebytes AdwCleaner and it did not find this either.

This is made to clear browser crap
