I want to change the program firefox uses to scan files I download. I think it doesn't have my AVG selected. When I download the EICAR test file, I don't get a virus alert. When I scan it afterwards AVG does recognise it as a virus. So I think something isn't set up right and because of that the scan on downloaded files isn't done by AVG.
I believe on recent versions of Windows, Firefox uses a service provided by Windows rather than starting the scan itself.
Does IE10 call AVG to scan the files? If not, this support article describes a way that the normal download scanning behavior might have been turned off in the Registry's Windows Policies section: Description of how the Attachment Manager works in Microsoft Windows. Scroll down to or search for "Notify antivirus programs when you open attachments" or search for HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Curr
The anti-virus I am using has built in settings to auto scan downloads, and my e-mail. Check your anti-virus program settings.
IE10 does call AVG to scan the files. I've looked at the file in the registry and it is turned on.
At first I thought it was bescause I uste the free version of AVG, but since it correctly finds it with IE10, I'm doubting again.
By any chance is Firefox's scan integration disabled?
