So MS's anti malware software does: 1. Execute NScript, a JavaScript-like language. 2. Run as high privileged, non-sandboxed process. 3. Intercept filesystem changes and run NScript code written to anywhere, including browser cache. 4. Do not check code signing. This is unbelievably ridiculous. It shall not happen to the software which claims to improve "security". As I always said, there is no good anti malware software. Everything sucks. An additional software is an additional security risk.
