Hi I downloaded Avira antivirus personal for my laptop but I'm not sure that it can protect my laptop so my question is am I right or wrong if I am wrong can you please tell another good antivirus for my laptop

Thanks.

Why do you think it would not protect your laptop? I use it for mine and have installed it on many of my friends' computers.

I believed that it was for despktop only not for laptop

Any AV program doesn't care what hardware the OS is on, its job is to look for suspicious files.

I have it and it works fine. A lot of people use it. I don't have viruses on my computer, but whenever I do, avira detects it. You can run a scan once in a while if you want to.
