*i was using the old version of Avast, but after failed to update it to the latest version, i uninstalled it and tried to install the latest version >> and end up failing to install it :cry:

  • Other security related software installed…?
  • Which AV(s) did you use before Avast…?

i was using avast > read the bottom part of my post

no other antivirus, but avast did mention baidu is on my pc

i’ve checked on add/remove program at control panel but no baidu thingy
and i’ve never installed baidu with or without intention; i always check if i’m installing or downloading things, so i’m sure it’s not installed through downloads or installation i knew

(i’ve cleaned the registry, using adwcleaner, JRT, malwarebytes)

but still cant install avast :-\

First, be sure to get rid of all remnants of your prior installed AV(s)…!!
https://www.avast.com/faq.php?article=AVKB11#artTitle

Then:

  1. Download Avast Free Antivirus: https://files.avast.com/iavs9x/avast_free_antivirus_setup.exe
  2. Follow instructions: https://www.avast.com/uninstall-utility (Run this tool for all prior installed Avast versions…!!)
  3. Reinstall Avast with the downloaded installer from point 1.
  4. Reboot.

no information on how uninstall baidu that i have never installed on that page

and i never see any baidu component (files and services) in my PC

still, when installing avast it insist that i have baidu antivirus and it suggest me to remove it

baidu webpage just shows how to remove it from control panel
i’ve tried from the control panel but as i can see there is no baidu program installed, so how am i gonna remove it if it’s not there?

i’ve used malwarebytes and adwcleaner to remove if there’s a PUP like that (the one i never installed or even download), but still cant install avast after cleaned my PC :cry:

Attach your basic diagnostic logs. (FRST)
Instructions: https://forum.avast.com/index.php?topic=53253.0

done

anyway, i’ve seen something in the installed programs in the additions.txt
the thing is called BufferChm (Version: 70.0.170.000 - Hewlett-Packard) Hidden

and it might be the cause for my add/remove program looks like the screenshot i’ve attached too
not really a problem for me but kinda annoying ::slight_smile:

if you’re not bothered by it can you fix that too? ;D
or should i post that to another section?

OK, now you’ve to wait a bit…

I have a similar problem similar too. Avast free will not install. The message is that I uninstall AVG anti virus , which was given the boot 4 years ago. I have disabled defender and nothing else is running. I can find no trace of AVG anywhere!!HELP!!

Start a new topic and post your logs there: https://forum.avast.com/index.php?action=post;board=2.0

any news?

Could you run FRST from the Administrator account please

with run as admin

[

[*]Reinstall Avast


done, i’ll try installing again ;D

*edit : i uninstalled avast with avastclear on your link and did it in safe mode (recommended by avastclear)

avast have installed successfully, thank you so much and sorry for the trouble :smiley: :smiley:

it’s nice to see avast on my pc again ;D ;D ;D ;D ;D

anyway, i installed smadav solely for usb protections because there was a virus hiding the contents of a flashdisk previously and avast only quarantined the virus shortcut, leaving the flashdisk empty while there are actually hidden files (cannot be seen even with the folder options), so i was using smadav that can fix those hidden things (looks like from registry) and also remove the virus shortcut

is it okay if i install smadav alongside avast? or is the new version of avast can do such thing so i dont need to?

Use MCShield: http://www.mcshield.net/

i’ll try mcshield, thanks ;D

You’re welcome.
