Unknown malware

I just performed a clean install of Windows 10. The only programs I installed are Avast Free and Chrome (which Avast itself installed for me.)
Now, every few seconds it tells me it blocked an infection

The details it gives me are:

URL: http://redirector.gvt1.com/crx/blobs/QwAAAHF3lnbmK-wFlemaY3l3BCOrQhs58MSM0PACaKZwzi
Infection: URL:Mal
Process: C:\Windows\System32\svchost.exe

I’m not familiar with any of this and it is driving me insane, because I have not even downloaded or installed anything else.
What do I need to do? Thanks in advance.

This is happening to me on one of my computers this morning also and it is getting very old very quickly. :frowning:

It seems to be associated with the use of my Chrome browser, since if I use my Internet Explorer browser it doesn’t happen.

Unfortunately I have been unable to find out if this is really an issue with Chrome, another case of Avast being being overly aggressive or if this computer is really infected. :-\

Chrome and Avast seem to be getting along fine on my wife’s computer and my other gaming computer with none of these particular infection blocked warnings whatsoever. :slight_smile:

Attach your basic diagnostic logs. (MBAM, FRST and aswMBR)
