backup exec software files cryptolocked

Hi all,

Recently we are suffering several intrussions into our systems files and servers. One of the servers was running symantec Backup Exec solution and the copies were been storaged in a RDX disk. We have to restore all documents and several systems files, but Backup Exec software files were cryptolocked too, so, we are not be able to run the resotre backup. Has anybody suffer this kind of issue?. Reinstall software?

Any Help will be greatly appreciated.
