svchost: windows update - no digital signature

[tssilvei]

Hello,

 

I have windows 8.1 with AVAST & Malwarebytes 2.0 (Premium). Avast has been prompting alerts for SVCHost downloading "am_delta_e......exe" & "nis_delta_patch_.....exe" from au.v4.download.windowsupdate.com with no digital signatures (as shown in the enclosed attachments).

 

Malwarebytes did not prompt any alerts or warnings!

 

Are these files/downloads legitimate microsoft sources?

 

Thank you!

If you did not initiate these downloads, then it seems suspicious to me. I would have someone check you system out for possible infections...

Thank you

Those are the virus defintions for MSE or windows defender. 

 

Cant hurt to double check the computer

 

Without the full urls i cant verify 100%. but thats what they should be and are downloaded by svchost.

Thank you for the responses. My windows defender is deactivated as I have AVAST & Malwarebytes Premium on my machine. All scans of MBAM & Avast report no infections. 

 

Does windows defender "silently" update itself even though it is deactivated?

i recommend following the instructions above and having it checked out. I really dont know if it does or not.
