If you are using smartphone than I would try to use minimal amount of apps possible, and try to get phone that supports installing open source operating system like GrapheneOS or something similar.
For computers I would switch to LinuxOS that has much lower risk of getting malware infections, and you won't have to install any antivirus software.
Using secondary aigrapped devices is also good for improved security and this can be hardware wallets, diy devices, laptops or old smartphones.
