Yeah, I binned Avast last year 'cos it was getting too fussy. Tried AVG for a bit but that was worse. It even blocked the PM forum.
So for the last 10 months I've been surfing happily just using Defender (with 10Bit Malware Fighter in the background). Defender has vastly improved over the last few Win10 updates and the UK computer mags have been giving it very positive reviews lately.
Of course, I have Tor Browser on hand for exploring some of the more nefarious areas of the web, but I rarely use it now that Chrome has an incognito mode. Many websites now block you from entering if you have an ad blocker active, but I find switching to incognito overcomes these blocks. You do then have to endure all the adverts because Adblock Plus doesn't work in incognito mode. Dunno if any of the others do.
Mike is still contactable through Deviant Art by the way.
