However, even with all these precautions, there's still a risk of losing your hard-earned money. That's why it's smart to use different wallets. If you choose to stick with Electrum, it's a good idea to spread your funds. This way, if one of your wallets gets compromised, it won't wipe out all your assets since you've already diversified your funds.
I don't think spreading your funds across different wallets like Electrum, Bluewallet, sparrow wallet etc. can help you out if your system is compromised with a malware. The numbers of wallets you have running on your computer does not really matter, a clipboard malware for instance can still insert itself in any of the wallets and steal your funds. The most important thing is to adhere to important security measures like never click phishing links, don't download apps from unknown sources and avoid downloading cracked apps.
For maximum security, you can store your funds on a hardware wallet or an airgapped device.
