NAV and some other AVs leave stuff behind on uninstall. however, I haven't come across any posts about AntiVir leaving stuff behind, so I can't say for certain.

For the most part you only know when something is left behind is when avast complains or doesn't properly install because of the presence of these registry remnants. So if avast is working fine you are probably in the clear.
Windows 10 Home 64bit/ Acer Aspire F15/ Intel Core i5 7200U 2.5GHz, 8GB DDR4 memory, 256GB SSD, 1TB HDD/ avast! free 24.2.6105 (build 24.2.8918.824) UI 1.0.799/ Firefox, uBlock Origin, uMatrix/ MailWasher Pro/ Avast! Mobile Security

 :) When "removing" any program from my computer, I always
    follow the same 3 steps : 1) Uninstall thru Add/Remove
    Programs ; 2) Use my computer's "Search" feature, select-
    ing "All Files & Folders" and using the appropiate Search
   "term" and delete everything possible it finds ; 3) Use a
    SAFE Registry Cleaner, to remove entries there.
    Concerning Ewido : after the 14 day "trial" ends, you will
    no longer have "realtime protection" or "automatic
    updates" . Since their updates come out as frequently as
    Avast, should get them at least every 3 days. You may be
    interested in an "Ewido Quick Guide" available at :
    www.greyknight17.com/spy/Tutorials/EwidoQuickGuide.pdf
    One word of caution : Ewido may detect "Win32Heu...Dialer"
    as a "Moderate Risk" that is associated with your ISP ;
    just "Ignore" it as I did when it happened to me .

So i just disable the resident scanner of AVG and i be fine?
No, NOT INSTALL which is different than disable.
After, you can set both AVG services to manual run (but you can let them to automatic).

How can use Install either AVG or Anti-Vir without the Resident Scanners?

Been a while since I had AVG, but for Anti Vir, when downloading Anti Vir, they'll ask you if you want to enable Active Guard, make sure you say no or uncheck the Active Guard.

If you only have one resident provider running, you can have another antivirus scanner such as Anti Vir.  :)

Just a suggestion...  ;)

How about Clamwin as a backup scanner.  It doesn't even offer resident protection anyway.  Also it incorporates into Windows OS so that you can right click on files to scan individually just like Avast (and many other AV programs of course).

I have read that Clamwin is renown for updating the Virus signature DB very quickly and will update the Database (DB) as soon as a new virus signature is known.  I have also read that a lot of email server providers are now using the Clamwin Virus DB for their AV protection.

I have been thinking of adding this to my system.  I was wondering if there could be a conflict if both Avast and Clamwin are set to automatic updates for the AV DB?
Processor: i3 2.53 GHz 4 GIG RAM, OS: WIN 7, Connection: High Speed, Virus/Malware Protection: Avast-2015, SpywareBlaster, Windows Firewall & Defender. Email: Outlook 2010 w/ POP Peeper Email Notifiers.

There is not such conflict. avast! and ClamWin can live together (if ClamWin is not set to scan emails, etc., anything, in background).
The automated update won't conflict for sure.

Having 3 av's on 1 system is a overkill.
Why? You'll call me crazy as I have 6 backup scanners...

What 6 backup scanners you use?

Seems over-redundant to have so many AV programs installed on a machine.  Wouldn't one be enough and use the popular online scanners that are available on the internet as so-called "back-up" scanners?

I have listen this a lot of times...
Testing software, not always on-line, off-line cleanning, compare features and detection, paranoid... a lot of reasons to keep my behavior.

Well Technical, I don't include you in this category.  You go above and beyond the call of duty to keep people fully informed on security issues and someone like yourself would need to install and test various platforms to stay informed.  I'm only referring to the average lay users. ;)

Thanks Culpeper. Sorry if I misunderstood your first post.
I do agree that average users shouldn't ever think on having that in the same computer.
By the way, wasn't you using NOD32?  ::)
