Windows Defender shows Trojan:Win32/Vigorf.A... nothing shows with Avast

[david713]

any ideas? I have run Avast Premium Security...but nothing shows?

There really is insufficient information to work with.
I'm also assuming this was an on-demand scan that you ran on Defender as it shouldn't be running with another 3rd party AV installed.

Is this a local file ?
If so what is the location, file name and what program is it associated with  ?

If Defender throws up an alert, you could attach a screenshot of the alert window.

yes, as a check and balance effort, I ran Windows Defender..

From what I see in your screenshot, this file (for your web cam ?) is within a .exe file (can also be a compressed file format) and within that a .cab file (cabinet file, aka a zip/compressed file).  These types of file are ordinarily dormant until the .cab file is run and extracts the contents. 

So unless you actually ran this fir[le Avast wouldn't scan it, if you ran an on-demand scan in avast you would also have to elect to unpack and scan these compressed files they wouldn't be scanned. Unless they were actually running and in which case the on-access scanner (File System Shield) would scan it/them.

What is your L: drive (unless these are just locations within the compressed file) ?

Do you happen to Have Hewlett-Packard computer or an HP WebCam  ?

HP computer...no webcam

[david713]

L: is local drive... (actually from an old laptop, cabled in)

[DavidR]

HP computer...no webcam

If you haven't got a WebCam and the HP WebCam software isn't installed/running I would have thought this a dormant risk also (if it is even that).

L: is local drive... (actually from an old laptop, cabled in)

Presumably there is no WebCam or not running on this old system/laptop  ?
If this is the case, this in my opinion is a case of paranoid settings in the Windows Defender scan.

- With a resident (on-access) scanner the need for on-demand scans (Windows Defender or Avast) is much depreciated. For the most part dormant/inert files are being scanned, the other active files are going to be scanned by the resident avast shields when they are activated.
