"Error" Access Permession for Kaspersky

[KLR]

Hello,

I have a little problem with Kaspersky antivirus, I had Avast antivirus for the past year, but I uninstalled it because I think I have some viruses and it doesn't help protecting my computer, I installed Kaspersky antivirus instead, but after installation it didn't run automatically, so I tried to open it by myself, and when I open it, this message pops up:
"windows cannot access the specified device, path, or file. you may not have the appropriate permission to access the item.".

Is there anything I can do about it? maybe a firewall settings or something with users permission?

Thanks in advance.

Maybe it's due to the self-defense module that prevents anything to tamper with the Kaspersky files. Try disabling it. Or if you can't try completely uninstalling it and then reinstall it again from scratch.

I tried re-installing it, but it didn't work, I tried to install Kaspersky antivirus, and later the Internet security, but none of them worked, about the self-defense module, I am not sure what am I supposed to do, or how to disable it, if you have any ideas, please let me know.

Thank you in advance

Are you running as Administrator? Is this the 'paid' for version or online scan?
