no.

If you use a hardware wallet for example, you don't necessarily need to use a paid antivirus software. The hardware wallet is quite secure by itself, and a free malware bytes and a windows defender software or something like that is enough.

If you use a desktop wallet, such as Electrum, the most important is to avoid phishing sites. Avoid installing program from Unknown sources... You need healthy habits online to stay safe.

Look for the official website to install the wallet, never download from third party websites

I think those paid antivirus consume too much computer resources and I don't like them.
