The scan found zero infected files, but when I looked at the report - unfortunately there is no mention of it now so I'm probably not calling it by its correct name - it showed five or six files that couldn't be scanned, and all are in the Alwil path, files ending .dll. No 'actions' options were available at this point. I had a similar... well, what I thought was a fault... occur on both my and my dad's laptops when we had Avast 4 - we ended up using Avira for a while, and at one point I wiped our hard drives and reinstalled, a habit I want to not get into.
I'm going to choose the boot time scan now and reboot. I've got Super Anti Spyware here too, I'll give that a go.
Thanks so far.
