Hey this is a warning BE CAREFUL ANF BACK UP YOUR COMPUTER. There is a really bad virus out there now that infects though e-mail with or without attachments!!! It slowly encrypts your entire computer with a 200 something bit encryption and then after its done its shows msg on your screen that says to send $300 to an address. Don't try to kill the virus as it will only make it worse. Can cause physical damage!!!
you have to wipe drive and start new. sorry for bad news
CryptoLocker is a ransomware program that was released around the beginning of September 2013. This ransomware will encrypt certain files using a mixture of RSA & AES encryption. When it has finished encrypting your files, it will display a CryptoLocker payment program that prompts you to send a ransom of either $100 or $300 in order to decrypt the files. This screen will also display a timer stating that you have 96 hours, or 4 days, to pay the ransom or it will delete your encryption key and you will not have any way to decrypt your files. This ransom must be paid using MoneyPak vouchers or Bitcoins. Once you send the payment and it is verified, the program will decrypt the files that it encrypted.
The malware is generally spread via email attachments in seemingly legitimate emails that claim to be from high profile companies such as FedEx or UPS.
There is currently no way of decrypting the locked files other than to pay the required ransom. And, if users do not pay up within the specified time, the decryption key, which is stored on the criminal's server, will be destroyed and your files will likely remain forever locked.
If you have uninfected backups, you may be able to remove the infection and restore your files. However, depending on how your backup system is configured, it is possible that the malware may have also infected your backup files.
Thus, Cryptolocker is a significant threat and computer users would certainly be wise to make themselves aware of it.
However, the above message actually does a rather dismal job of educating users about the threat and telling them what to do about it should their computers become infected.
The warning does not even name the threat, nor does it describe in any meaningful way how the ransomware is distributed. And, the malware does not encrypt the entire computer as claimed in the mesaage, but rather locks up certain types of files. Computers with the infection are still operable.
The warning does not link to any expert advisories on the topic that would provide recipients with further information. And, the rather cryptic claim that the malware can "cause physical damage" is misleading. If victims do not pay, they may never recover their files, but there is no suggestion that the infection will physically damage the computer's hardware. Moreover, while users may not regain access to the encrypted files, the malware itself can be removed without "wiping the hard drive".
