Trojan.Dropper.Gen?

Today I ran a Full Scan with Norton, and it completed saying all was good.  It didn't find any threats.  Then I ran the Malwarebytes program, and it detected this:  

Trojan.Dropper.Gen    Malware with this location file:  c:\windows\temp\appx.808pi34xepji0ylgl6m3lvyee.tmp

Why didn't the Norton Full Scan pick this one up?  Malwarebytes directed the removal of the threat and said restarting my computer would complete the threat removal.

Okay, yes, I'm more than a tad puzzled as to why Norton didn't detect this.

If anyone knows more about this, please share your knowledge with me.

Thank you for any assistance.

Sincerely,

Buoybells

Re: Trojan.Dropper.Gen?

Hi, buoybells.  Win32:Dropper-gen [Drp] is a generic detection used by Symantec and other antivirus products for a file that appears to have trojan-like features or behavior.  Here is the Symantec KB article re this item.

https://www.symantec.com/security_response/writeup.jsp?docid=2002-082718...

I can't explain why Norton didn't pick it up, but if MalwareBytes has removed the threat, then I wouldn't be concerned.

Possibly because Norton concentrates on antivirus, and programs like MBytes concentrate on PUPS and PUAS.

Also, this malware exhibits trojan like behaviour, ----- {My underlining}

If full scans by Norton and MalwareBytes are clean, then I don't think you need to worry.

It was a temp file. If you cleaned out your temp files prior to scanning you would be all set.

Thank you Pats and F4 for your feedback.  I ran both scans again and nothing is detected at this point.  Hoping it is definitely gone.  Can't help but feel upset that Norton didn't detect it.

Thanks again.

It is a temp file. It was not a malicious item. Temp files should be removed regularly. Especially after web surfing. The more important thing to remember is what you did and where you went to cause this. Keep in mind that no antivirus can detect 100%

Your welcome. If you download CCleaner it will cleanup your temp files and cookies.
