The malware I said above can be due to outdated antivirus, we need to update the antivirus to its latest version. Hardware wallets are very safe, ~
anti viruses are good but they won't always protect you against everything. you still have to be careful yourself, don't download any random things you don't trust, don't visit shady links,... and obviously you must use cold storage. hardware wallets are good but that is not the only option. for "storage" you can always use a paper wallet that costs practically nothing.
