I've used a number of Ashampoo products for a long time, in my experience they range from very good (Office - licensed from SoftMaker, Burning Studio), to questionable and probably pointless (driver updater, registry cleaner/system optimizer). They can be a source of very economical software if you pick & choose offers. They are very persistent marketers, I probably get about 3 or 4 email offers a week, which I don't mind, but I suppose I could try opting out and see if they stop. They actually seem to be decent folk, so I'm guessing they would.
Their anti-virus has been around for a good many years, I tried it early on when there was a $4.99 for a year offer, but that was before it used the current dual engine design. It worked happily enough and I certainly had no breaches, but overall I found no reason to stop using Avast Free.
