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

[REDACTED]

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

Attach your basic diagnostic logs. (FRST)

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 

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

[Asyn]

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!!
