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.

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?

Your only solution is to restore to a time before infection.
Use a restore point or a backup.

Okay for people who have to deal with this in the future.
1 Clean workstation.
2 Restore from system restore point
3 Restore file from "Restore previous version"
4 Search for encrypted file extension and delete
