Every file download get a "contains virus" message

[Rotty]

I have a Win7 X64 machine running IE10 , every time I download a file it says it contains a virus and is deleted

I have tried disabling Malwarebytes and that makes no difference

Tried a few things I have found on web with no joy

any ideas?

Thanks
