Ok so it keeps popping up, annoying but it gets worse. It popped up just after I had run a clean and I noticed that it had also created and left behind a cookie - ipm-provider.ff.avast.com A cookie that CCleaner will not find on analysis and will not clean.   You can force force delete it, right click it in the 'Cookies on Computer' list and delete from there. But it will come back next time you open CCleaner and the pop up appears. Are Piriform still going to insist tha
