Virus / Malware that changes file extensions to .pdf.xdtorli or .*.xdtorli CryptoWall virus

I have a work station that where the "internet stopped working". When I check the work station I found many issues. I ran mbam, TDSSKiller, and ComboFix. I believe this removed the issues, but I now need to repair the damage. Question: Is there some else I should check to make sure malware / virus has been removed. Question: How should repair all the files that have been changed from #####.pdf.xdtorli, #####.xls.xdtorli, ....?
 I have the log file for scan if need. The rootkit found was Rootkit.Boot.Cidox.b

I started in the wrong place... original Q&A string.

I'm running through this...

Be my guest and run through it, but to the best of my knowledge there is no "fix" for cryptowall and its' derivatives.  The only option is restoring from backup or a system restore.

well, that's pretty much what it says as well.
How about on networked drives? rename the fill is the issue I'm working on. Is that pretty much the same: Restore or Replace?

Security

Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection. Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.
