Out of curiosity I’ve tested Unchecky on a virtual machine and does absolutely nothing to avoid installing unwanted software during the installation of Easeus Partition Master free. I have even accepted the installation of that software and it has not done anything.

Maybe the author of the program needs to update his program? Possible to help by letting him know.

Here is the answer to why Avast Installed itself…at least for my customers…
See this article…
https://www.ghacks.net/2017/11/19/avast-bundles-ccleaner-with-avast-free-antivirus/
Avast bought Piriform - the maker of CCleaner and started bundling it with it’s free CCLeaner download.
Check it out…do custom installs of CCleaner form now on and UN Select AVAST.
Cheers!

Thanks, johnr4 
but I didn’t install CCleaner at all, and don’t have it on my computer, so it must be something else in my case.
That article also referrers to the installation of Ccleaner if you already have Avast Free.
It doesn’t mention anything about installing Avast.

I installed FileZilla yesterday and randomly see avast on my machine this morning. Never saw a single option to Not install avast. Now I have to waste hours researching this crap, uninstalling this 2GB program and installing avastclear.exe to run in windows safe mode. Fkn ridiculous. You guys are garbage malware, cooperating with other software to bundle silent installs. Who the hell would ever willingly opt to spend 2GB memory installing random software they didnt ask for in the first place?

@ 1277sramirez
This topic relates to a version of CCleaner (from Piriform, purchased by avast software) installing avast.
As far as I’m aware FileZilla has nothing to do with Piriform or Avast, https://en.wikipedia.org/wiki/FileZilla, so what is going on with your system doesn’t appear to be the same as this topic.

@ Davidr
The topic literally is called “Avast Installed itself”. I turn on my computer today, lo and behold Avast Installed itself. You want to argue over semantics? Just one google search shows that this problem is rampant, people are reporting similar occurrences across hundreds of forums…Many of which unrelated to CCleaner. Instead of doing something useful with the information I provide, you want to play forum police.
Figures I would get that reaction from a company distributing malware.

Please don’t snap at an Avast user who is trying to help you. That accomplishes nothing.
This is what I found doing a simple search: https://unchecky.userecho.com/communities/1/topics/866-filezilla-3290-installs-avast
Sounds like you’re not using Unchecky and, you didn’t use a custom install when you added FileZilla.

I’m here on this forum because Avast just DID install itself on my computer as well. How? Why? Before anyone tries to tell me I did it myself: I have had this laptop since 2010 and at that time installed my usual Norton anti-virus. Last September 2017 I bought another laptop and stopped using this one. I put this one in the bottom drawer of my dresser. My newer laptop is having issues which I don’t want made worse before I can send to warranty company, so a couple of days ago I took this one from the drawer (and no, no one else can use it). As soon as I started it there was a pop-up from Avast stating it wanted to update or something. I thought it was a weird fluke because I have never, EVER, had Avast and the computer had been in the drawer forever. I clicked out of it and checked on my Norton, yep Norton still there, I ran updates etc just in case.
Today I got another pop-up from Avast wanting to update. I looked under Uninstall or change a program and to my extreme surprise it was installed on 10/14/2018. The very day I began to use this laptop again and got the pop up to “update.”
Also, not only did it install itself apparently as soon as I started the computer for the first time in over a year, I have never installed nor have I heard of either CCleaner or Piriform.
Ummm…???

Same thing with me. I have not installed CC Cleaner or any other software in months. I’ve never heard of Avast until it popped up on my machine. I was using AVG cloud care. But as I am typing this and trying to find AVG on my machine, it no longer exists. Was AVG un-installed when Avast installed itself?

AVG CloudCare was rebranded to Avast CloudCare ( https://www.avast.com/cloudcare ). This change was communicated with existing customers via email and via our partners.

YES, Avast does install itself!!! Avast says it does not install itself BUT it does. You do not have to ask for it or want… they install it on your computer via a backdoor - they attach it to another program when you are NOT aware of it. They are not an honest company… they get a kickback from programs like CCleaner free etc. That is why CCleaner will let you download their program for FREE because - I know you have heard this a million times - there is nothing for FREE! BUT, the way AVAST does this is Crooked… The AVAST program is like a weed in your yard, you didn;t ask for it but it got there anyway because you were watering and taking care of your yard because you wanted something else but the WEED grew in place of your flower. AVAST is MALWARE. they are a crooked company, they are similar to your best friend scewing your girlfriend. You trusted your friend (CCleaner in this case) but in the end he scrfewed your girlfriend or in this case you caught a disease… AVAST the virus protection you did NOT ask for or did NOT need. We use Paid powerful programs on our computers WHY would we want an inferior virus protection on our computer when all it will do is cause issues with your Paid virus protection. You cannot or should not ever run TWO virus programs on your computer. AVAST knows this BUT does NOT CARE… neither does CCLeaner. It’s time to get rid of BOTH!!! Spread the word folks, uninstall this WEED now! Go get a real job crooks, all your doing is making life hard for other folks. POS

I am a computer engineer. I am here to confirm without a doubt that Avast, or malware masquerading as Avast has in fact self-installed.
It is likely the real deal Avast as it installed right after I updated and ran CCleaner. I ALWAYS do advanced installs because you’re stupid if you don’t. There was nothing in the details or fine print about Avast infecting my computer.
I say “infecting” because that is exactly what it is. Like most people in my field, I disable all forms of anti-virus and Firewalls as soon as I buy a PC with Windows pre-installed.
Of all the garbagey, useless fcking sorry gimmicky so-called anti-virus programs out there conning average users into using their shtty services, Avast stands alone as the absolute worst, and you are a f*cking tool if you use it.
Not only am I unable to uninstall or force it closed, as my Admin privileges have been revoked courtesy of Avast. I cannot even access my own programs menu.
Now I have 2 choices, I can waste part of my day eradicating this virus from my machine or I can install the only good malware software on the market (Malwarebytes) and let them take care of it for me. I am choosing the latter.
I will tell you what I’m not gonna do though, I am not installing more Avast software to get rid of the Avast software already infecting me. So you can suck mine and everyone else’s c*cks who were lured here by Avast’s malicious practices.
I would not wipe my sh*tty ass with anything produced or owned by Avast, and am sorry to hear about Piriform whose products used to be good until the day Avast bought them apparently. I am ceasing the use of CCleaner, Speccy, Recuva, all of it immediately and suggest anyone else finding themselves on this forum do exactly the same. There are better programs out there anyway in 2018, CCleaner is not the only option like it once was.

Ccleaner is still one of the bests. It’s your computer and your choice.
The language used in your reply is also your choice. 
The installation of Avast occured because during your custom install of Ccleaner you didn’t block it’s installation.
I hate that trickery as much as you do but don’t intend to stop using a product because I made a mistake.
I generally learn from my mistakes.
I’ve just logged in to my mom’s computer, because she complained about it not responding too well and there it is: Avast AV on top of my chosen AV Sophos. I suggest you stop BSing people about their consent to install your product. Guess what? My mom is not an admin on her computer. I am and she doesn’t know my password. That leads only to one thing. You are using OS’s exploits to install this crap on non-admin user profiles. This is trespassing and you will hear from lawyers soon.
