viruses, trojans, worm, tootkits, etc are all types of malware.

True viruses are hardly seen (if any) for years.
The term anti-virus is for many years a misnomer.
It is a leftover from “the old days” when the only threat came from viruses.
Nowadays “anti malicious activity tool” (or something like that) would be a much better name as the software doesn’t only protect against viruses.
And as I have said many times, security start with the user not with hardware/software.
Eddy this was very helpful to read in following up my input into the dp.alexa issues.
Do you consider CCleaner would have reported computer misbehaving merely for a file being stored in Avast (maybe in quarantine)?
Might I be correct in thinking that CCleaner decided appropriately it was safe to remove (redundant?) files associated with Avast?
Like your term Malicious Activity Tool - I’ll call them AMATs. So I using Avast Premier, CCleaner and Malwarebytes I have three potentially conflicting AMATs?
For this “newbie” it seems that these programs to some extent provide different facilities and help 
Asked and partially answered in your previous post - https://forum.avast.com/index.php?topic=194367.msg1394327#msg1394327 - re CCleaner.
Agree my initial query was as a result of CCleaner detecting what it considered to be a problem relating to dp Alexa. Looking at a broader perspective now in relation to input from others.
It seems that CCleaner perhaps detected a malicious file that Avast had not been able to delete but had put in quarantine. Could it even be a file rendered obsolete by Avast updates? Alternatively might probing of Avast by CCleaner caused reactions by Avast that CCleaner reported adversely?
Am I wrong to feel happier that dp Alexa seems to have been deleted completely from my system by CCleaner rather than being kept in quarantine? Malwarebytes now gives a clean bill of health?
Have heeded advice from computer magazines that Windows Defender should be de-activated because other AMATs are much more effective - guess some people are not aware of this.
This is the only apparent conflict I have had between AMATs and in this case I seem to have been better protected by not relying on just one product.

avast quarantine is a protected area, no program other then avast has access to it

CCleaner is not a security program, it does not detect malicious files
had not been able to delete but had put in quarantine.
