Many computer users have been attacked by KEYHolder as of later which encrypted large number of data on the infected PC. KEYHolder is a new type of crypto-ransomware. The same as other family members like OphionLocker, CryptoLocke, and CryptoWall, KEYHolder is able to encrypt photos, videos, documents and other formats with ppt, txt, pptm, pptx, psd, pst, ptx, r3d, raf, raw, rtf, rwl, srf, srw, as extensions in the target PC.
After the successful encryption of KEYHolder, every time you try to open the file, you will get notification that the file cannot be opened because it seems to be damaged, too large or corrupted. To decrypt all the files, KEYHolder request victims to go to www.torproject.org websites to buy the key and scares computer users that from now on they have only 10 days to pay or the key will be permanently deleted from the server and the encrypted files will never be back. However, you should note that there is no guarantee whether your files will be restored or not after you buy the key.
Facts have proven that most of the victims still cannot get their files back after the payments. Therefore, we get the lesson, always make a backup for the important data, do not take the risk to lose the money if the encrypted files are not so important, and take immediate action to get rid of KEYHolder completely from your system now.
