Yes I know to not store seeds in password manager. But I did do that with some of them. But I guess this situation is similar to using software wallet.
Except it isn't because you unlock your password manager constantly every single time you use your computer, whereas you might only enter your wallet password a couple of times a month.
So you telling me if it finds nothing at all, then my computer is safe from anytype of malware/keylogger etc?
There is no malware scanner or similar in existence which can guarantee it will find 100% of viruses/malware.
But I can't use this computer to download the software wallet because this computer does not support windows.
What OS are you using? What software wallet are you trying to use? Why not just use something like Electrum?
