How do I uninstall AVG anti-virus

I am sorry but I do not understand. Do you have an issue with Ubuntu we can help with? Can you explain further?

Thank you for your reply. First of all I just recently switched over from
Windows and am having a lot of trouble with all the proper commands. I
downloaded AVG 7.5.45 for Linux from the Grisoft website. I've been using
it for years in Windows and I am on a dual boot with XP. Anyway I never
could get it to update, either scheduled or manually, so I decided to just
uninstall it and just use Aegis which seems to work fine. AVG is no good to
me if it can't be updated. The problem is I can't get it removed. I type
in "sudo apt-get remove AVG" and it tells me there is no such file. But I
can go in the file system and see all kinds of AVG files. I don't get it.

How did you install avg? Did you use a .deb package or install it with apt-get, or did you install it from a .tar.gz file?

In the first case, you might use a different package name.

Use the command

dpkg-query -l '*avg*'

to find the right one. The result gives you the name to use with

sudo dpkg --remove <packagename>

In the second case, you would need to look in the INSTALL or README file from the .tar.gz file if there is a removal functionality.

I hope this helps

This is what I'm talking about. You asked me to use the command

dpkg-query -1 '*avg*'

This is what I get

jtx472@Northgate:~$ dpkg-query -1 '*avg*'
dpkg-query: unknown option -1

Use --help for help about querying packages;
Use --license for copyright license and lack of warranty (GNU GPL).

jtx472@Northgate:~$

Thanks

Also, it was a deb file installed with gdebi-gtk

This is really a question for GriSoft.

You were asked to use:

dpkg-query -l '*avg*'

not:

dpkg-query -1 '*avg*'

Assuming the correct command lists an avg package, you can remove the package using:

sudo dpkg -r packagename

Where packagename is whatever is returned in the Name column from the dpkg-query command.

Cheers

Oh I see...but how do I get that line in there? I can't find it on my keyboard. And goodnight my friend.

Never mind. I got it.

Can you tell me the package name from that? Thanks

Yep... it is avg75fld.

You need to give the following command

sudo dpkg --remove avg75fld

I hope this helps

Sorry to bother you again my friend but this is what I got:

jtx472@Northgate:~$ sudo dpkg --remove avg75fld
Password:

You might need to start it first, since the removal script seem to fail otherwise:

Do first:

sudo /etc/init.d/avg start

and then:

sudo dpkg --remove avg75fld

I did as you said:

Personally I would forcably rip that sucker out.

sudo dpkg --remove --force-all avg75fld

Seems like nobody can figure out how to remove this bugger from my computer. My real problem with it is that I cannot update it. And no virus scanner is any good without regular updates. So if you can't figure out how to remove it maybe you can figure out how to update it.

Ok, here's another way.

We can stop dpkg running the shutdown script (which is clearly broken).

sudo gedit /var/lib/dpkg/info/avg75fld.prerm

In that text file (which I don't have a copy of because I dont have avg installed), you should find one or more lines that have the following at the start:-

invoke-rc.d
or
/etc/init.d/avg75fld

Or very similar

Go to the start of those two lines (or how ever many there are) and put a "#" (hash/pound/gate) symbol at the start.

Then save the file and repeat:-

sudo dpkg --remove --force-all avg75fld

You commented the wrong bit.

The line

if which ...

should not have a comment in it..

The line immediately after it should.

Again, you have not commented out correctly.

You need a # in front of the line that *starts* with

invoke-rc.d

(which you have not done)

and the line that starts

/etc/init.d/avg

(which you have done correctly)

I'm confused. Would you show me exactly where you want th "#" marks or is
the following correct? Thank you

case "$1" in

   remove|deconfigure|upgrade)

       if which #invoke-rc.d >/dev/null 2>&1; then
           #invoke-rc.d avgd stop
       else
           #/etc/init.d/avgd stop
       fi

cp /opt/grisoft/avg7/data/set_vers.cfg /opt/grisoft/avg7/data/upd_vers.cfg

       ;;

   failed-upgrade)

       # just try again

       if which invoke-rc.d >/dev/null 2>&1; then
           invoke-rc.d avgd stop
       else

Aaaaargh :)

This isn't nice is it? :) Seems my changes have caused an error in that script.

Remove the lines

       else
           #/etc/init.d/avgd stop

completely. They appear twice. Then try again. This is file butchery but it should work.

#! /bin/sh
# prerm script for AVG for Linux

set -e

# possible arguments: remove, upgrade, deconfigure, failed-upgrade

case "$1" in

   remove|deconfigure|upgrade)

       if which #invoke-rc.d >/dev/null 2>&1; then
           #invoke-rc.d avgd stop

       fi

I don't know about you Alan but I'm becoming brain dead. I think I'll give
it a break for a while. Thanks much for all your efforts.

Hmm, add a line after the

           #invoke-rc.d avgd stop

and before the

          fi

saying something like..

          echo "stopping"

Just in case anyone else stumbles across this and wants to sort it out without going to the drastic lengths of re-installing, they were on the right track.
I commented all lines beginning with invoke-rc.d or /etc/init.d/avgd and added a line after as echo stopping. This did the trick. My advice is don't bother with avg on linux. It maybe good (relatively) on windows, but its crap on linux. clamav is the way forward IMHO. if you even need an anti virus of course.
I'd just like to say well done to Alan Pope for patience and perseverance. And well done to Thomas for sticking with it and learning. There's nothing like a nasty config problem to get your teeth in to linux :-)

Thanks for the info JT. Thomas

Thank you guys for working through this. I had exactly the same issue and have just come across the posts. I commented out the invoke.... lines, the /etc.....lines. I also needed to comment out the fi command and added the the echo stopping command as stated in the previous posts. It all worked fine.
Thanks again for the help Alan and JT. Like Thomas I am new to Linux. I find some parts ofthe operating system absolutely fantastic (the quality of most of the software is great), while some parts (like drivers or lack thereof) painful. I am learning to love it though!!!!!
:-)

Just edit the file /etc/init.d/avgd and replace exit $? with exit 0 at the and of the file.

Oh my god,
How am I to do this when I have no idea what the heck your talking about?

Hello, Im new to Ubuntu and Linux in general.
I know XP but not this OS.
I installed AVG for the same reason, i used it on Windows and it worked good but now I cannot update it.
I guess I had to be logged in as root even though I installed it with sudo?

I used the install package .deb and it automatically came up with "Synaptic Package installer"
As far as I can tell everything worked properly but now I get the "I don't have permission to get update" error message

Is there an easy way to get rid of this AVG for beginners?
Like an uninstall with the Synaptic Package installer? Please say yes?
AVG I assume does not care about this issue since it still has nothing about it on the site where I got the download.
It seems that they could have said "install as ROOT! or something. Point is: they don't support this version so they don't care.
I think I will not upgrade my AVG for windows next time... What do u think about that AVG?

If uninstalling and re-installing Ubuntu is easiest then I will do it. God knows, I installed and re-installed windows so many times trying
to get it working again that I have experience in that at least. That is why I went to Ubuntu in the first place.

If anyone can help me let me know before I remove Ubuntu!

With Many thanks to all above.

With the new version of AVG, I had to alter steps a little bit ... Below please find a set of instructions that should apply to 7.5 and 8.0

Removing AVG

Firstly, lets find out which version you have ...

~$ dpkg-query -l '*avg*'

You'll get something along the lines of....

un avg71fld <none> (no description available)
ii avg75fld 7.5.45_a0973 Free edition of antivirus solution with GUI.
un avggui <none> (no description available)
un avglinux <none> (no description available)
un wmavgload <none> (no description available)

or

un avg71 <none> (no description available)
un avg75 <none> (no description available)
ii avg85flx 8.5.287 AVG Anti-Virus for Linux
un avglinux <none> (no description available)
un wmavgload <none> (no description available)

the bit we're after is the one beginning ii

now edit the file /etc/init.d/avgd and replace exit $? with exit 0 at the and of the file.

e.g.

~$ sudo gedit /etc/init.d/avgd

finally ...

~$ sudo apt-get --purge autoremove avg75fld

OR

~$ sudo apt-get --purge autoremove avg85flx

(Or whatever is reported after ii above)

For version 7.5 you should get something like this

Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages will be REMOVED:
  avg75fld*
0 upgraded, 0 newly installed, 1 to remove and 0 not upgraded.

Now, the original article this is based on seemed to point to you still having some remnants of avg left in /opt with version 7.5 -- so, let's have a quick look

~$ cd /opt
~$ ls

if you see either an entry for either grisoft or avg - you need to remove them manually

~$ sudo rm -r grisoft

OR

~$ sudo rm -r avg

PLEASE BE CAREFUL sudo rm -r is EXTREMELY powerful - and you get no 2nd chance. If you are a little unsure - leave the files where they are until you are SURE you are happy with what you are typing.

Phill.

thank you, helped me as well.

TY Popey! Post #13

I am running a Web/Mail Server on Ubuntu 14.04.1LTS on a low end PC - 2.8GHz P4 HT 1.2GB RAM 80GB HDD.

I had everything setup and ready to go and then I realized I needed anti-virus so I installed AVG 2013 FLX deb. Before the install of AVG I was using less than 300 MB or RAM. After the install I was over 800MB.

I had to simply rip it out using:

sudo dpkg --remove --force -all avg2013flx

Success! TY.
