If it was a keylogger, that will not do. As I understand, the safest is to use a separate computer, not connected to the internet, to store your wallet and sign transactions.
Yes .. I decide to do it like this. [ ... ]Move wallet do other location and connect to Inet only when I will want to use it.....
That is still a bit dangerous. The safest procedure is to never connect that computer to the internet, transfer the transaction data to it by USB stick, and transfer the signed transaction back to the main computer in the same way.
I don't think that there is a sufficiently safe way to carry several thousand dollars in bitcoin outside your home. If you do not control the physical environment where you sign the transactions, there seem to be ways to steal your bitcoins, even of you use a Trezor.
