Change the message on start up.How do you change it?

Hi. When I start up my computer,it says "protected by Avast".Its possible that this was there after I first instaled avast a few days after buying and using my computer.This computer had nortons internet security 2012 ipre installed when I bought it in June 2012.

I added these after I bought it:
1))avg free standalone linkscanner
2)avast free anti virus.

I let nortons run out then installed zonealarm free firewall antivirus.
I also had to uninstall avast back then too.

I decided that I wanted to go back to Nortons/avg linkscanner/avast so I uninstalled zonealarm (even though it was quite good-just preferred nortons)then installed nortons then avg linkscanner and tried to reinstall avast.I just left it with nortons and avast.

Can someone give me step by step instructions to remove "protected by avast"?

Thanks.

Have a Merry Christmas!

Hi Thanks for your reply.

I currently dont have avast installed on my pc.I uninstalled it about August this year.It still shows that its protected by avast even though its not even on there.

As I said before Avast isnt listed there at all.Its not showing anywhere.

I'll keep nortons.

you can change the start up message by using regedit in start menu type regedit.exe and open it.
navgate to this key

"HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Current Version\Policies\System"
click on system and you will see right hand panel a set of keys.
double click "legalnoticecaption" and in the data value put your desired cation if avast is using this you may see avast's data.
after that double click "legalnoticetext"
put the text you desire their.
If avast message is present delete it and type yours and if you want no message delete the data value of both and leave it blank and save t ,restart to check it.
Hope this works for you.

Also check this if it doesn't fix it

I installed revo.It wasnt listed on there and I also have iobit uninstaller and its not in there either.
I followed your other instruction and most of the suggestions you made werent in there.

As I dont have avast anywhere on my computer I do just want to edit it where it says "protected by avast" or just so I can leave either make it it blank,maybe disable it altogether.

Thanks for your help.

can you post a screen shot , photo by camera is just fine i just want see where it appears.
