I had do deinstallate Norton Antivirus manually as it was no longer possible through the deinstallation features of Windows 2000 Pro. I did it like described by Symantec Support and run Rnav2003.exe and have gone trough all the steps described.
Now deinstallation seems to have worked only partially, for one problem remained: when I click on a folder or icon with the right mouse key, of if I select a folder and then press the delete key, Windows Installer is automatically activated and pretends to Install Norton Antivirus. I have to close the Installation procedure several times, till it leaves and the normal function of the key (right mouse or delete) is resumed.
How can I get rid of this behaviour?
Thank you for your help.
