I’ve recently had the nasty experience of being spammed by the avast notices about this certain URL, 102f.net/al1000.html. When it first happened I tried running the Avast scan and Malwarebytes scan, but the notices keep appearing when I go to certain sites (such as imgur) or even when I turn my computer on.
Added are my scan logs as required, except the one produced by the aswMBR which for some reason would start a scan but never complete it.
