I received a notice my files had been encrypted with a strong RSA-2048 algorithm and that I had to pay in bitcoins to restore the files.  As part of the message, it lists five pages to get the decrypter. It states that before paying as a test I can decrypt some files by going to one of the links. None of the links will open saying there is an internal server error.  Does anyone have any suggestions as to what is happening and/or what I should do?

More information is needed to determine specifically what infection you are dealing with since there are many variants of crypto malware (file encrypting ransomware). RSA-4096 / RSA-2048 / RSA-1024 are encryption algorithms and not an explicit way of identifying a particular ransomware infection.

Are there any obvious file extensions appended to or with your encrypted data files?

Did you find any ransom notes? These infections are created to alert victims that their data has been encrypted and demand a ransom payment. Check your documents folder for an image the malware typically uses for the background note. Check the C:\ProgramData (or C:\Documents and Settings\All Users\Application Data) for a randomly named .html, .txt, .png, .bmp, .url file. Most ransomware will also drop a ransom note in every directory/affected folder where data has been encrypted.

You can submit samples of encrypted files and ransom notes to ID Ransomware for assistance with identification and confirmation. This is a service that helps identify what ransomware may have encrypted your files and then attempts to direct you to an appropriate support topic where you can seek further assistance. Uploading both encrypted files and ransom notes together provides a more positive match and helps to avoid false detections. If ID Ransomware cannot identify the infection, you can post the case SHA1 it gives you in your next reply for Demonslay335 to manually inspect the files.

If this is something new...our crypto malware experts most likely will need a sample of the malware itself to analyze before anyone can ascertain if the encrypted files can even be decrypted. Samples of any suspicious executable's (installer, malicious files, attachments) that you suspect were involved in causing the infection can be submitted here (https://www.bleepingcomputer.com/submit-malware.php?channel=168) with a link to this topic.

From the description it sounds like Nemucod, which is decryptable. ID Ransomware will identify it properly via ransom note or encrypted file and give you a link to the proper information.
