Thank you. I definitely rushed into it in an effort to get my business back up and running and obviously made a bad decision. I appreciate your input and am looking into an alternate wallet. This has been quite an experience.
Thanks again.
Bitcoin Core itself isn't a "bad decision". It's a GREAT wallet, and I use it regularly. However, it may not have been the best choice for your particular needs.
Be VERY careful about any advice you take from anyone on this forum. Scammers can create an account here and pretend to be helpful, then they can take advantage of your inexperience and lack of knowledge to try to trick you into turning over control of your bitcoins to them.
Even if you think you are talking with a trusted member of the forum with a good reputation, there are scammers that have created userID's that look VERY similar to a trusted user's ID so that they can impersonate that trusted user and send a PM to trick you.
It would be best to keep conversation in the public thread (and not in Private Messages) so that others can warn you if some advice you are receiving is bad advice.
One of the fastest and easiest wallets to set up quickly ( which also allows you to import a private key ) is the web hosted wallet at blockchain.info. It isn't the most trusted wallet. They have had issues where browser plugins and other malware have been able to access someone's bitcoins while they are logged in. They've also had issues with insufficient transaction fees, and failing to save a newly generated bitcoin address at times. Therefore, if you do choose to use their wallet service, I'd suggest making certain that you are using a computer that you are VERY confident doesn't have any malware on it. If you don't plan to keep bitcoins on the wallet for longer than it takes you to send the one transaction, then you should be able to set up a blockchain.info wallet in less than 2 minutes, and import a private key within another couple of minutes. 5 Minutes from when you start, you could already have the bitcoins sent.
Please note that there is no guarantee that the attackers will decrypt your files for you after you pay the ransom. They could just take the bitcoins and disappear. You'll need to decide for yourself if paying the ransom is worth that risk.
Also note that there depending on how sophisticated the attack is there may be tools that have been created that may be able to recover your files for you without paying the ransom. If you have enough time, you may want to read through this:
