While Microsoft detects and removes Locky, we recommend you disable macros to help prevent this and other macro-downloaded threats from infecting your PC, and then only enable macros that you trust, on a case-by-case basis. To help keep your enterprise secure, consider using a trusted location for files in your enterprise, then you can store documents that require macros there. You can also use our cloud protection services to help boost your protection; this, and other advice on how to help keep your PC protected are outlined below.
