Title: Avast install breaks windows 7
Post by: barry.fitzmaurice on January 04, 2016, 05:36:15 PM
Tried 3 times now, reboots near the end of installation, but Windows won't start. Tries Startup Repair but this always fails.  Have to go to System Restore to make PC usable again.

Have similar issue.  First -  I have a license on this machine....went on vacation for a few weeks and didn't start computer the whole time.  I start it up, and it says that I am using the free version now, and that I need to update.  Do an update...hangs on update.  Computer shuts down by itself.  Uninstalling avast doesn't work either - I had to disable the engine on startup, and I am going to try a fresh install of the software...and put the license that is already on the machine back into the software...

Perform a clean installation of avast.

- Download the full installer for the version you want ( https://forum.avast.com/index.php?topic=179855.0 )
- Remove avast through control panel (skip this step if you get a error)
- Run avastclear
- Make sure all remnants of previously installed av's are removed ( http://www.ache.nl for links to tools/instructions )
- Reboot
- Run the installer
- Reboot

Anytime I run ANYTHING Avast...it hangs....Even tried AvastCleaner to remove everything....no dice...
Title: Re: Avast install breaks windows 7
Post by: Eddy on January 04, 2016, 06:05:33 PM
Boot in safe mode and run avastclear.

Post by: catman2112 on January 04, 2016, 06:18:11 PM
Tried it twice now....Avastclear window pops up, get the nice circle animation....and it just hangs...hard drive doesn't do squat.  Machine works just fine without Avast running..

You did started avastclear in safe mode ?
Title: Re: Avast install breaks windows 7
Post by: catman2112 on January 05, 2016, 01:19:12 AM
yes. Same thing happens.  Ran it in safe mode with and without network support....it starts spinning, and then it will just keep spinning over and over and over,,,and slowly things start to come to a crawl... This isn't over a 10 second period either...first time I let it run for 30 minutes on lunch, and when i got back it wasn't even spinning anymore.  Second time, I watched it for about 12 minutes and watched it do the same thing.

Ok, time to try something else.
Get Farbar, run it and attach two log files to your next post.
We need FRST.txt and Addition.txt

Title: Re: Avast install breaks windows 7
Post by: barry.fitzmaurice on January 05, 2016, 06:56:30 PM
No, does the same.  Gets almost to the end of the install progress bar, reboots, and says "Windows failed to start, perhaps a recent hardware or software change caused this".   Back to system restore :-(
Title: Re: Avast install breaks windows 7
Post by: catman2112 on January 05, 2016, 07:08:40 PM
FRST is attached....I have to Zip "Additional"
Title: Re: Avast install breaks windows 7
Post by: catman2112 on January 05, 2016, 07:14:09 PM
And ZIP doesn't work...so....I opened "Addition.txt" and there was a slew of 0's int he middle of it...

Well this is interesting.....now it wont' get past the Ctrl+Alt+Del page....tried both normal and safe modes....  Hard drive is going bonkers on startup with the CTRL+Alt+Del screen....

I will work with it a bit here to see if I can get past that...
Title: Re: Avast install breaks windows 7
Post by: catman2112 on January 06, 2016, 04:41:41 PM
had to do a system restore to two days ago to get the Ctrl Alt Del to work....

Thoughts?

OK if you can now try Avastclear that should remove the remnants
Title: Re: Avast install breaks windows 7
Post by: catman2112 on January 06, 2016, 06:55:23 PM
AvastClear Still hangs....in either regular or safe mode.
Title: Re: Avast install breaks windows 7
Post by: catman2112 on January 06, 2016, 07:26:59 PM
Is there a list of entries somewhere that I can pull out of the registry? I have no problem doing that if it means I can use this computer again...the previous FRST Fix hung the computer at the CTRL-ALT-DEL screen - is there something in the text file posted here that I can take out that would prevent this from locking up?
Title: Re: Avast install breaks windows 7
Post by: essexboy on January 06, 2016, 07:28:47 PM
What do you mean the control alt del screen
Title: Re: Avast install breaks windows 7
Post by: surfcity on January 06, 2016, 08:11:35 PM
Tried it twice now....Avastclear window pops up, get the nice circle animation....and it just hangs...hard drive doesn't do squat.  Machine works just fine without Avast running..

My computer does NOTHING except start now following the last Avast update, which apparently installed itself. Nothing else works about it. Not the cursor, not the arrows, not Escape, not Ctrl-Al-Del, nothing. I can't start it in any other mode, because none of the keys work (except the on/off button). It's nothing more than a very expensive paperweight at this moment. I have no idea how to fix it.
Title: Re: Avast install breaks windows 7
Post by: catman2112 on January 06, 2016, 08:14:15 PM
@Essexboy -  the computer would boot - and prompt me to hit CTRL+ALT+DEL to login...except hitting CTRL+ALT+DEL did nothing....no login screen...nada...not even in safe mode.

It works NOW after I did the system restore (to 2 days ago)
Title: Re: Avast install breaks windows 7
Post by: essexboy on January 06, 2016, 08:23:48 PM
OK so it is set to log in individual users rather than just go straight in

You could use revo uninstaller to try and remove Avast
Title: Re: Avast install breaks windows 7
Post by: surfcity on January 06, 2016, 09:34:42 PM
How are you people doing anything? I can't get any part of my notebook computer to work at all since this happened. It turns on, boots up (but won't let me boot into safe mode because I can't move the arrows to switch from normal boot-up), and then just sits there until the screen goes black and I have to do a hard shut-down. I would love to do a system restore to the morning of 1/1, but I can't get into that part of the computer (or any part of the computer for that matter) since this happened. I don't know what to do. :(

Trying REvo uninstall  - never used this one before...but it seems to want to use the default uninstaller to begin with, which of course hangs anyway.  Tried the "Forced Uninstall" as well - giving that some time to do some magic, but the HDD seems to just be pulsing every second and nothing is actually happening..

More to come

Ran Housecall and HijackThis to remove what I could...Housecalle found 2 things, and HijackThis found a bunch of stuff, as it normally does...some of which weren't issues so I didn't delete them.  I'm going to run FRST again and post the results after the Hijackthis removals...

Could you fix the host file first using the download on this page https://support.microsoft.com/en-gb/kb/972034

Also did you set the group restrictions ?

Are these the GPO's you are referring to?

HKLM Group Policy restriction on software: %appdata%\*.exe <====== ATTENTION
HKLM Group Policy restriction on software: %appdata%\Microsoft\Windows\Start Menu\Programs\Startup\*.exe <====== ATTENTION

Those were set from Bitdefender's anti ransomware/bitlocker protection I believe.  The only reason I say this is because those two files are listed in the protection options of the software.  Note: I disabled this software long before I posted here with the problems...

Well it looks like we may be in business...that Revo program is pretty slick and it hunted down the remnants (one of which I am certain was causing the hang of course).   I am currently reinstalling Avast now that I CAN reinstall it...

Ok, so here's the deal....I ran REvo again, and it found a bunch more Avast stuff...so I deleted everything, rebooted, did it again.  It found more stuff again...deleted, rebooted again...did it again, and it didn't find anything.  Rebooted, did it again, didn't find anything.  Rebooted.  Installed Avast (I accidentally used the online installer instead of the full installer) BUT it worked...installed in about 2 minutes.  Inserted the license file without an issue.  Rebooted again...took quite a bit longer to reboot this time, but it finally did and I think we are in business!

From what I can tell - the update installer failed a few days ago and for some reason, there were two instances of the software - one being the main instance and one being a reference for the updates or something? I'm not really sure -either way - the update failed....but after all this it is working now

Post by: catman2112 on January 08, 2016, 09:16:18 PM
I didn't at first...when I was looking into Revo tho...the second time, the registry pointed to a different folder....almost like Avast tried to recover itself or something - I can't really explain it and I am not 100% sure either.  Wish I knew what caused it int he first place but as the old Italian saying goes: if it ain't broke, don't fix it...
