Why desktop wallet? Stop using desktop wallets unless you aren't using the desktop for internet browsing, PC have many ways to get compromised even if you are been careful,
PC is no exception, any device can be easily compromised if the owner is careless enough. The first version of Electrum only supports the desktop version, and I believe the developers have considered the vulnerability of the device.
hardware wallet and mobile wallets are far more safer
I think mobile devices lose almost 90% of their functionality if they don't have internet connection enabled. What about your previous statement about no internet browsing?
