After version 17.3.2291 i found avast bugged, it creates various slowdowns with other applications and malfunctions of the same.
Returning to the previous version all returns to normality
Thanks so much. Is 17.3.2291 the last stable version? Or should I go down to 17.2.2288?
I’m not sure what are your issues exactly, from your post it seems both of you had issues with the GUI. I don’t really have a GUI issue, maybe because i don’t really use the GUI that much so my fix was just regarding the filesystem.
Uninstalled Avast after this update, glad I didn’t purchase license as I originally intended for this year.
This update caused huge performance issues on my computer (delays in other software, video freezing issues) - and since every update lately has caused more harm than good, I’m not planning to return. What’s the point of beta when final version is one big mess?
I’ve been loyal to avast for past 8! years, but enough is enough.
(And yes, I know I can repair or downgrade, but I’m not going to. It’s easier to uninstall and use different product that works than fixing software that’s intended to run quietly in background and do it’s job).
Had it for longer than you and always did recommend it as the most sensible due to all the transparency (now taken away) and configurability. The last thing you want from an antivirus is for it to slow down your system to a crawl. They need to realize that the vast majority of users won’t report the issue on a forum, but will be pissed nonetheless. I think there are enough people posting the same issues here for them to acknowledge the problem and roll back. The main problem here is they refuse to even acknowledge it, meaning there will not be a fix. If this keeps up then I am not staying either. Enough alternatives out there that can do the job.
Suprise/no suprise, searching for the word alternative, this one came up https://webcache.googleusercontent.com/search?q=cache:QDtvNu48-fYJ:https://www.reddit.com/r/techsupport/comments/2xhdtu/after_10_years_avast_and_i_are_pretty_much/+&cd=3&hl=en&ct=clnk
2 years ago. And yes, i’ve held up to their endless nagging for quite a long time now, i forgot what i did, somehow managed to disable the upsell nag or that they cut it down, although i’m not seeing it anymore, i do realize it gets bloated overtime.
- Stop trying to upsell a free thing to a paid thing to me. If you wanna nag, once a month is fine, not every single day for every single 6 hours !
- Stop trying to shove in things i don’t need, i dont need secure browser, VPN, mail shield, and 101 of these bloatware !
- Stop trying to impress the new generation by changing your UI every day.
I can go on, but it’s pointless. Not even 1 rep came up to this thread or other tread to solve any issues.
If you’re looking for alternative, that reddit thread is pretty good.
I have my Avast Free set up the same way as the poster above me. No real need for those other functions.

This was my answer to one of the folks who attended a presentation and wanted further information
about the various Components offered by Avast.
I use those 3 shields, software updater just for info if new flash/java etc. come out and the browser extension since it puts a mark next to google results to tell you if a link is safe before you click it. Other than that, I also untick everything else.
Would be nice if someone actually addressed the issue we have. This is quite unrelated to the main issue of a major performance hit for many of us due to the latest update.
Mail Shield - useless if you dont use mail software
Browser Protection - this one annoys me, might be good for some
Software Updater - this one is OK, but supports almost nothing (also, ninite.com is good for checking new versions)
Browser Cleanup - mostly useless (havent seen any toolbar in years tbh)
Home Network, Passwords - useless in most cases, there are better solutions for both
And all of this is useless if your PC runs like crap because of Avast.
I used to be proud of avast being Czech company as I’m from Czech myself, but since last few versions, everything was going downhill. Why buy AVG when they can’t even make their main AV working.
I made clean install of windows few days back to one of my family member, incl. avast installation. Can’t wait to hear from him that PC is now running like a crap.
Please don’t compare apples with oranges. The image was posted to answer a question about the various components.
It has nothing to do with addressing the problem you are having.
Sorry, but I haven’t seen any question about those components. Only people saying they are not needed.
Don’t really see a question there. The first mention of components was calling them bloatware, not asking what they are for. Either way, they are optional so I am fine just un-ticking them during setup.
For everybody who wants to go back to the working 17.3.2291, you can get it here
http://www.filesetups.com/windows/anti-malware/avast-free-antivirus-17.3.2291
Took a while to find since most sources link back to the avast site that only hosts the latest.
I did my own paranoia check by downloading the latest version and comparing the hash to the one from Avast. It checked out. I also checked and both the latest as well as 17.3.2291 are digitally signed by Avast. I just installed it and everything seems to work fine as before. Make sure you only update the virus definitions (the ones in the offline setup are from March). Do NOT update the program itself or you will get the issue back.
For anyone that happens to be a gamer and are experiencing your games not loading up properly or just freezing and lagging, it turns out that one redditor found out it was the File System Shield that was a major Culprit.
From the Overwatch Reddit on people trying to figure out why they can’t play it.

I just upped my sub for another year, but I think I may uninstall and find a new antivirus. This has been the 2nd time that Avast has messed up something on or about my computer, the first being that after an update, it changed my main drive that I run windows from to another and rendered my pc useless until I got troubleshoot help from the person who built it for me.
Does this mean any large files I downloaded since the last update are ruined? How large is large?
I did use the offline installer. Will try to remove Avast and do a clean install and see if that works.
if so then this maybe gives u idea what to… http://www.tomsguide.com/us/best-antivirus,review-2588-5.html it talks about 7 most known antiviruses Wdefender included its ppls ratings site with info, Avast team has messed up before, but dam this time they really have messed up & broken Avast, more i read happier i am that i decided to read before updating & luckily my avast doesn’t say i am not protected update like few ppl have mentioned, in my PC the notifications have always been bugged sins 2015 or 2016 ver no more nodifications when update is available, but its kind of good i would have disabled this notification anyway :D, no idea is 17.3 stable enough (i have this ver, but it works as protection) cause i haven’t scanned for months (some say there is issue with scanning) if PC feels like usual & u haven’t noticed anything weird there is no need to scan (but maybe it is harassing my sys bit some programs have become bit slower over few years. but i have seen worse, or its cause of the programs own updates can’t really say) before this update i always updated without reading comments here, i won’t update & i won’t uninstall it yet, i w8 for future & see what future brings, if next update is a mess to maybe i switch antivirus as well, GL with new antivirus
BDW who use sub ver should sue the team to teach them a lesson cause they do some pointless crap to like always changing there UI, & i bet that’s part of the issue why they mess up to much pointless crap have been put in to Avast
i quote to wrong person before, u know some sites have the option above & some below a post & it times it makes me do mistake like this 
Well, folks, I asked for help and suport, and I was told to WAIT for instructions about the update of the program.
So I did, and today the instructions were: now you can update. And I did.
The exactly same problems I had after occurred again. Or worst.
Nothing changed, this update is a serial killer of PCs, be carefull, DO NOT UPDATE, you will pay a heavy price.
I hope I’m helping you all, guys.
Good day.
Still waiting… for help.
as posted before, just use this version

update virus definitions, leave program - do not update it 
AVAST: FIX IT?!
Still has the issue of the “Behavior Shield” turning itself OFF at times in Windows XP PRO SP3 systems … does not happen on my Windows 10 Home 64 Bit system
