Update:

Comodo fixed a problem with the firewall, good to go. Comodo's scan found not much. So I opened MalwareBytes again thinking the problem was solved. Nope and the culprit is MBam swiss army knife.exe. I put spaces to make it easier to read. I uninstalled MalwareBytes freebie and installed the trial version of the premium version. The scan completed without a problem. However, MBAM, like it did the last time, flagged iobit ASC and Uninstaller. I've told it to ignore iobit. During the scan 26 PUPs were found. By ignoring iobit that number was reduced to 11. A couple of them had to do with Internet Explore IE, not Edge but IE. The rest were left over items in the registry from two programs I tried but turned out to be crap. One was a video downloader, not the Youtube one either but one I replaced it with. Now I use 4kVideo downloader which is much more efficient and passed Comodo's scrutiny, which btw Youtube failed. One year of the premium version is 40 bucks. That works out to about $3.33 a month. Not too shabby. 

Yeah, I'm looking to get the premium version of Malwarebytes.  Was going to do it today, but finances are a bit tight since Louis left... everything is now a third share instead of a quarter.  That will improve when my son gets back to work, which is dependent on getting a car.  Hopefully that's not too much longer as one is in the pipeline.

Anyhow, I have a 14 day free trial, so I'll stick with it until next fortnight.

there is no difference between malwarebytes freebie and premium/trial of the same version number.. (i don't mean the functions), it's the same installer that installs the same files. freebie is basically premium disabled. i'm guessing the one you installed is a newer version that fixed whatever problems or even reinstallation of same version did the job.

not sure what flavour of comodo you have but having 2 real time protection on at the same time is bad, just in case you don't know.

Yep. Definitely stick with one only realtime scanner.

There are other proggies with specific functionality which won't affect them...such as 'Ransomfree', and manual scanners usually aren't a problem, but realtime ones can have conflicts.

Oops! Then maybe the freebie version got borked somehow considering the .exe at fault is present in both.

it could have been an old version vs new version thing may be? or i don't know, your installed version got borked somehow

Yeah from reading this you shouldnt running iobit, and malwarebytes. If this is happening, maybe you should check to make defender is off. The only thing to remember is somtimes some programs run windows firewall. Agree with the one realtime scanner thing. 

Well, I did install the new version of MalwareBytes and where it says exclusions added both the ASC folder and the exe. It was supposed to ignore ASC but it didn't. I tried updating ASC to the latest version and MalwareBytes deleted it. Funny how Comodo has no problem with it but MBAM always did, not the first time this happened. So in the meantime I uninstalled MBAM until it can be sorted out.

Im confused the asc, and exe are two files you need to search through. Mater of fact if you exclude these two files then you could exclude an infinate number of viruses. You need to know the name of the files you are excluding.

Last year there were a flurry of reports that MalwareBytes was reporting false positives, and the local (Utah and Nevada) company that made my laptop recommended that it be replaced by Super Anti-Spyware.  I had been using MalwareBytes up to that point and have been using Super Anti-Spyware since and have had no problems with either.  My point is simply that there is an alternative to look into.  I have no connection with either company.

I've had Malwarebytes come up with a heap of false positives, mostly to do with Advanced System Care.  I too did an exclusion on all ASC stuff, but Malwarebytes keeps listing them as PUPs.  I just ignore those now and look for and quarantine items that are malware and stuff I neither want or need.  Yeah, the false positives are annoying, but better those than using a lesser scanner that misses those nasty files we'd rather not get.

Yup and I discovered a faulty driver caused one of those instances. Last time it happened I checked the event viewer and found out something, don't remember what, was running continuously. Traced it back to an ATI Radeon driver. So over to AMD's website I go and download the latest version. So far so good.
