I'll second that. I accidentally installed Avast onto my Windows 10 system because it was piggy-backed on the latest version of CCleaner. Once installed, Avast is difficult to uninstall, and requires a reboot to get it fully off your system (if it's really uninstalled; I'm not sure). S**tty move by Piriform.

Avoid the problem in the first place by opening the Registry Editor (type regedit in the search box), then go to HKEY_CURRENT_USER / Software. You will see a key 'AvastAdSDK'. Right click on this, click Delete then confirm the deletion.

Of course, the honest solution would be for Piriform to stop hiding the option box in the first place. It really is an underhand practice. I used to use Avast and recommended it to my friends, until it became so bloated with extra unneeded features. Anyway, with the improvements to Defender with Windows 10, there is no need for a third-party anti-virus program in any case.

Please reread my post from 21 November about deleting that key in the registry. Then you wouldn't have had that problem in the first place. But you need to do it each time. I agree it's a pain, but we know how to avoid the Avast install.

I recently installed avast! free antivirus and it kept giving me a warning that some file (bootloader or something like that) had a warning because of it's "decompression rate". After some research, found out it was harmless and recommended that I uninstall avast! for an alternative. So I uninstall avast with the uninstaller it came with, however, now when I check my console log, every 10 seconds it shows a log for "com.avast.helper" that says "Error connecting to master socket: connect ( ) : No such file in directory". How can I permanently stop this, and possibly remove any remaining fragments left from avast!? I tried going into my library, but the application folder for avast! was no longer there.

Open Avast! Preferences and uncheck or "open" File System Shield and disable it. (If you are on line and not downloading anything, then you are still protected. I disconnected from my router to do this stage.)

Return to finder and select the first part of the system pass and get it to allow you to choose that path as part of the exclusion. That will copy the path to the "Exclusion" window on Avast! It may take trial and error to get it to appear, but you will get at least part of it to move. Then you can edit and add the rest of the filepath to the exclusion window.

After you do this, either click done, or repeat the process until all the inaccurately identified files are added. You can also add the entire Library or other folder to the exclusions, but I suggest not doing that, since in the unlikely event you are infected with malware, it might go unnoticed.

Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.

Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.

Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.

Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.

If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, EasyFind, instead.

Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.

The simple reboot that Kappy suggested seemed to work guys (thanks Kap!). It kept logging even after I uninstalled avast!, but after the reboot, no more logs. On another note, anyone familiar with the bootloader warning? The file it was warning me about was a ".dmg", and depending on where I was searching, some people said that "all .dmg files are downloaded and if its bootloader.dmg then it's a virus or malware" but I've seen some that say it's harmless and an factory-installed part of OS X. Can anyone shed some light? I'm fairly new to mac, and I worry sometimes about my computer's safety.

Hi, I need to remove a program, which is called AVAST Security from my MAC. I know usually, you just grab a program from the finder menu & drag it to the trash, but it will not go into the trash, as a message pops up saying it is still open. I took it off the bar at the bottom, but I have NO IDEA how to close this program. If I click on it from the finder menu it wants to ask if I want an upgrade. The dang thing will NOT close. HELP!!

Then download and run Find Any File to search for any files with the application's or developer's name in the file name. For example for Avast software you'd do the following search:

Go ahead and read it, just beware that Discussion went off the rails with differences in terminology. I concluded the eventual cause was installing "Avast" prior to upgrading that system to Catalina or perhaps Mojave. That may describe your dilemma. Although "Avast" was easily removed using their uninstallation instructions, I surmise that upgrading macOS caused those directories to henceforth become sealed off and inaccessible, meaning their uninstallation instructions will no longer apply.

It's not safe, but then again it never was. The uncomfortable next step is a nuke and pave and never do that again, preceded of course by a Time Machine backup so that you can repopulate your Mac with your essential work files.

Not sure why it would say I do not have access to my own computer!! When I say yes, delete them, it keeps popping this same screen up. The only good thing so far, is since I deleted over 112 files, I am not getting any more pop up messages from AVAST that I have "unsecured" files that need to be taken care of by them. When their software asked me for permission to access my complete HD, I refused.

I really do appreciate your helping me on this. I went to the Avast web page & sent them a message asking them to help me delete this APP, but since I got a "free" intro copy, they have no info from me, and no record or desire to help, besides the fact that they are closed down mostly because of the Virus thing. Any ideas on how to proceed?

Hi Old Toad. Nice to hear from you again. Hope you and your family re doing OK during this shutdown. In response to your answer, I have to say & tried the uninstall directions, but my Avast is a "free" basic model, not an advance Pro model, so no, there is no way to go to a menu to shut this dang disease down and uninstall it. Every time I try to uninstall I get a message that says I have to close it before I can do that, but there is NO WAY to close the dang thing. I think it is somehow latched onto my HD and is slowing down my access to web pages. I will go to their "help" desk on their web page and threaten them with legal action. Maybe that will move this along.

Hi Old Toad, Well, I turned on the MAC in Safe Mode, which only took a few seconds, downloaded the FAF software from the App Store, and went searching for anything with "Avast" in the title. There were 112 files!! I was able to delete all but about 7 of them. When it got down to the AVAST app, and a few other Kernel files that I tried to delete, I got a window that popped up saying I did not have authorization to delete the files!! I closed the FAF program, re-booted in safe mode, and tried again, and it asked me for authorization for FAF to delete the files, which I did, but I STILL got the message that I don't have the authorization to delete the AVAST files. I am so livid!! Grrrr....What do I do now??

Hi Old Toad, other things have kept me away for a while. Tried to do as you suggested, but again, got the pop up window that says "You do not have permission to move the files to the trash." I am not sure what to do now. Somewhere else on line someone suggested re-adding the Avast software and then using their un-install program. I really am afraid to add their software again into my computer. Not sure if it is safe. I tried contacting the manufacturer directly, and got a blanket email that they are not working right now. ( Probably due to the Covid. Any other ideas?
