Title: Avast Clean Un & Re-Install (How-To)
Post by: thekochs on December 22, 2013, 02:08:25 AM
Before Proceeding
Chances are nothing will go wrong with a clean un-re-install but if something does you want a backup.....thus,
Old A/V Uninstall and/or Cleanup
Avast does not like other A/V or remnants of previously installed A/Vs on PC.....even old Firewall or Internet Security programs.
Save yourself a lot of headaches to make sure you clean up old installs....even if you already uninstalled....in other words "cleaners".
Here is Avast FAQ with "cleaner" links: Avast FAQ (http://www.avast.com/faq.php?article=AVKB11#artTitle)
....another site "cleaner" links: https://docs.google.com/document/d/1k_GS_9sETRJHgKveyvov27Qb2-85DbbWDF0XwW1OaU8/edit?pli=1
....another site "cleaner" links: http://www.ache.nl/index.php?location=mal-01
....another site "cleaner" links: http://singularlabs.com/uninstallers/security-software/
AFTER the above cleaning of "remnants' I also use/run CCleaner: https://www.piriform.com/ccleaner
It is very easy & reputable to remove temp & old files, etc.
It even has a registry cleaner (with backup) that is one of few that is safe. CC Reg Cleaner (http://www.piriform.com/docs/ccleaner/using-ccleaner/registry-cleaning)
It also contains an uninstaller that removes troubled programs that won't uninstall. CC Uninstaller (http://www.piriform.com/docs/ccleaner/using-ccleaner/uninstalling-programs)

Since this is a proposed discussion on the sequence published above, there's something I'd like to bring up...

Have you personally taken apart (or seen the source for) and vetted that 3rd party cleaner tool ("Rejzors Uninstall Utility") you're recommending?

Do you know for a fact that Avast's own uninstaller doesn't remove everything necessary to effect a full reinstallation?  What, EXACTLY, does Rejzors Uninstall Utility remove that Avast's own cleaner tool does not?

From what I gather, Rejzors Uninstall Utility was written by a well-meaning member here, and in all likelihood is benign and helpful, but I can't KNOW that without doing more work - and I suspect you can't either.  I mean no disrespect, but I should think anyone who's concerned about security should ALWAYS question the advice to run a 3rd party utility from another web site. 

Simple question that examines the motivation of the author:  If it's legit, why not post a list of things Avast missed to help the user clean up himself, and to help Avast improve their own cleaner tool - instead of publishing an extra "cleaner" tool?

Before anyone flames me for questioning something that's "unquestionable", I'd like to mention that I'm against running ANY kind of "cleaner" tool.  I'm of the opinions that it's all too easy to dig a hole in one's security deeper, and if the Avast folks don't think it needs to be removed, then maybe they know what they're doing and there's no reason to remove it.

FYI, I've been through an uninstall / reinstall recently (yesterday), and the problem I was having where settings would not stick was solved by doing so - all without running Rejzors Uninstall Utility.

Edit:  Better wording

Can't say I have not had same thought so guess folks could use that part as "optional".
Another suggestion from "me" (as opposed to the cut-n-paste I did above) is to use CCleaner after the uninstall.
I personally have used this for many-many-many years and is the only cleaner I'd trust.
I am like most folks and never think using a reg cleaner or file cleaner is good.....causes more problems than fixes.
However, I've found this a very reliable tool and with a lot of pedigree.
After install I'd open and run the "Windows", "Application" tab analyze, then run cleaner.
I'd then selection the Registry item to left and run the Scan for Issues & Fix Selected Issues. 
Note, it allows you to backup the registry items it is cleaning.....always a good thing to do.
http://www.piriform.com/

For me my AV/Malware protection strategy on my personal PCs is:
Avast Free
MalwareBytes {Yes, I run the active shield and daily scan, does not conflict with Avast)
CCleaner {I right click daily on Recycle Bin & Hit run....cleans all those nasty temp files, etc....virus haven}
CryptoPrevent (Ran this util once to change Group Policy to help with CryptoLock}

As far as commenting on the 2nd uninstaller......I won't blast you for your opinion but many very senior folks have use it in this forum and by the nature of this forum there has to be a level of trust.  For me, I'm still on Avast V8....tried V9 on one PC and rolled back to V8 because clearly wasn't ready for prime time.  I've found that major code rewrites of complex programs take 6-9 months to get stable.  While there are a lot of great people on the forum (and in BETA) that have time to do the testing I do not...don't want to be on bleeding edge....I rely on using my PCs daily and their downtime would kill me.  Anyway, I digress.  My point is the nature of how invasive the suggestions in this forum can be (great example is the virus removal tools) that there has to be some level of trust.  With that said, I do agree that a "member's" code should really be questioned.....more so, why Avast Team doesn't quickly incorporate (if truly needed) into their avastclear.  All I can say it that if you truly need a "totally" clean install this is one more tool in the war chest. :)

Adding pic of when you launch uninstaller in normal Windows and asks you to respond to boot to Safe Mode.
No need to hit F8 and PC restart.......

Also, this clean uninstall process takes care of EMU update removal for Avast.
Obviously, new install puts back in.

http://www.filehippo.com/download_avast_antivirus/15860/

Do you have another link to this version?  I removed Avast 2014 from my Windows 7 64-bit machine and tried installing this version (twice), but it keeps installing 2014.9.0.2011.  I'm having trouble with 2014 and would like to roll back if possible.  Thanks.

I do not........perhaps others do.  My guess is that there is such an intense push to move everyone to Avast 9 that the last legacy links for download of Avast 8 are being asked to change.  I can tell you the Avast 8 installer/download is 128MB...which the FileHippo shows but as you said when you download the file is ~85MB...which is Avast 9.

Designed for:

Not XP?
Title: Re: Un-Install & Clean Install How-To
Post by: DavidR on January 18, 2014, 01:20:02 AM
Whilst it doesn't explicitly state XP, I think it may be that RejZoR didn't test it on XP. It may work. But if it doesn't since you would be running this last (after normal uninstall, plus avast uninstall utility) it wouldn't hurt to try.
Title: Re: Un-Install & Clean Install How-To
Post by: CCV on January 18, 2014, 02:27:08 AM
I did try it. Seemed to execute with no problems at all.
The author of part of it is actually Mark Russinovich, and I believe he does know what he's doing.

Maybe it is overkill too, but I have my reasons...

New install hung my system up at the 'quick scan will now launch' point. Could be other cause for that.. No internet connection, perhaps?
Powered off and restart, no problem. Sure is a *clean* install! :)
Title: Re: Un-Install & Clean Install How-To
Post by: DavidR on January 18, 2014, 01:59:55 PM
Well the on-demand scans don't require an Internet connection as far as I'm aware, or where would those off-line systems be if the wanted to do a Quick Scan.

Is there an option in the Free to not install GrimeFighter ?
This how-to link does not show GrimeFighter under Tools (look in Custom section): http://www.avast.com/en-in/faq.php?article=AVKB3#artTitle
.....but the pick from other thread showing in someone's "Change" in Windows Program Features shows it.
I'm just wondering if the Avast link is dated or if some versions have and some don't.....or it is forced installed and you have to uninstall after ?

Thx.

Updating the first post should bump it to the top again as the content has changed and considered unread. So no need to keep bumping.

Well for you I don't think it will change as you 'have read it' when compiling it.

For those coming in and using the 'Show unread posts since last visit' option then that modified post will have been unread, so it should have moved.

Obviously I can't test that either as your new post (not modification) would have also been shown in the 'Show new replies to your posts' option.

A ride to the top.
 
Obviously, all the senior members put the details of first post in threads to show clean install but hopefully seeing thread for those can save some trouble.  Besides the first post......which is really combination of many other folks (not me).....there are other good inputs in this thread.
Anyway, think worth keeping this alive/visible for awhile.

Well the on-demand scans don't require an Internet connection as far as I'm aware, or where would those off-line systems be if the wanted to do a Quick Scan.

During my most recent clean install (with internet enabled), what happened was (at the 'now will launch quick scan' stage) that avast! opened my browser to http://www.avast.com/en-au/lp-pt-welcome?utm_source=prg_ise_90_3&utm_medium=prg_lnk&utm_campaign=free2paid&utm_content=prg_ise_en-au_welcome-page&p_var=.%2Fprg_ise%2Fen-au%2Fwelcome-page&p_elm=83&p_lex=0&p_lid=en-au&p_lng=en&p_lqa=3&p_lqe=1&p_lst=3&p_lsu=36&p_pro=2&p_bld=empty&p_vep=9&p_ves=0&p_vbd=2013&p_hid=04f7446b-61be-41e9-a2c3-7e51697470bb&p_ram=4012&p_cpu=7.5

Seems a bit unnecessary, to me, besides, I always thought it a good idea to be offline while uninstalling one antivirus and replacing it with another.
And, anyway, it still didn't launch the promised scan.
