  2. Misplaced trust in the client: JavaScript code cannot be expected to run as healthily and normally as intended since some information embedded in the raw source code might be extracted by attackers and fall into their usage.
  3. Browser and plugin coding errors: Due to a wide range of browser capabilities that JavaScript (JS) provides, flaw like buffer overflows could be incurred to allow attackers to write scripts which would run any code they wish on the user’s system.

Sandbox implementation error: Microsoft Windows allows JavaScript source files on a computer’s hard drive to be launched as general-purpose, which makes JavaScript, like VBScript, a theoretically viable vector for a Trojan horse. popup ad should be removed rapidly before additional problems being caught in sight.
