Thanks to all for all your comments. My original concern was about the 500+ invalid firewall entries, whether to delete them, and also where is the deleted software hiding, and how do the same invalid entries regenerate after being cleaned?

What is your first opinion scanner?

Thanks, Hazelnut. Reading through those forums cleared up the cause, but I'll still wait a while before reinstalling MB. Funny how a lot of trusted software I've used for years no longer has my immediate trust anymore. My reaction to all this is 'if it's not broke, don't fix it".

This morning Malwarebytes was acting peculiarly, slowing my I5 laptop to a crawl, popping up tray notifications that didn't work, and in general even not allowing task manager to work! I'm just getting sick and tired of all the time spent just trying to keep my laptop clean. I just had to finally uninstall Malwarebytes, and thing are running well, at least for now. I've posed the invalid firewall question to Piriform, and their take is the these registry entries can be safely removed. I explained that when the obsolete software box is unchecked these 500+ entries disappear. My laptop has restore points, and is image backed up, so I just let Ccleaner delete all the 500+ invalid firewall entries. Nothing changed, the laptop still is running decentlly So at this moment in time I have Windows Defender, Glasswire and Ccleaner working, and I'm using Disk Cleaner for cleanup along with Ccleaner.

Thanks mta. I can understand the seeming need in today's software for as many services as possible. What I can't understand is why Piriform would add some potentially dangerous services, especially since MS itself denies their use. Were the older OS less susceptible? I guess so, since years of use by most of us never wrecked our PCs. In fact, up until a few weeks ago I used the registry cleaner, which seemed to operate as usual, finding some leftover entries, but 500+ seems a little much. I suppose that Piriform is aware of this, and I hope they offer a fix, but now I'm not sure I would use it at all. For a kind of comparison, I used MS Disk Clean app, and it seems to clean just as well as Ccleaner, and when you allow Disk Clean to clean Windows Update it finds even more, in my case about 5gb more. So if you don't use Registry cleaner, wht's the point of Ccleaner at all?

Thanks to the moderators, mta and Andavari, for their comments. Like probably most of you, I have been faithfully using Ccleaner's Registry cleaner for years. Their comments have had their impact; with Win 10 an evolving OS it's probably best to leave the registry alone, which I will do from here on. The one unanswered question is the prominence that Ccleaner gives to their registry cleaner. Do they know something we don't?

MS seems nto feel that registry cleaners are unnecessary, as you do. These entries on my PC don't seem to be causing any of the problems you've mentioned. I've checked for unnecessary programs and deleted them. Aside from using Ccleaner and Revo Uninstaller, do you know of any other ways to delete unused software? I wonder therefore why Ccleaner gives such prominence to its registry cleaner. It's all a bit confusing.

I'm running Win 10 64bit Pro, and Ccleaner is finding 500 + invalid firewall entries when running registry cleaner. When I uncheck the obsolete software box CC finds no entries. If I delete these entries all seems okay, but a few days later all these deleted invalid firewall entries reappear. Somehow, whatever is producing these entries still remains on my computer. I'm running Windows Defender, Malwarebytes and Glasswire. Any ideas?
