Safely withdrawing from a paper wallet

[RabiaAbid]

Hi all,
I have a significant amount of bitcoin (~10) in a paper wallet (the actual private key is printed on a piece of paper). To improve security measures and possibly sell forked coins, I would like to transfer the funds to a new address.

I understand the technical procedure - sweep the private key into a wallet software and send to the new address. But what security aspects should be considered?

Some online resources recommend myCelium, but while I am cautious I do not trust my Android devices to be free of malware. I plan on using a PC with a Live CD linux distro (e.g. Ubuntu) installed on a fresh USB disk. What wallet and withdrawal procedure would you recommend? Does the Electrum Cold Storage feature has any benefits for a one time transaction?

Thanks!
