You need to run Malwayerbyte Antimalware. Malwarebytes have created an easy-to-use, simple, and effective anti-malware application. Whether you know it or not your computer is always at risk of becoming infected with viruses, worms, trojans, rootkits, dialers, spyware, and malware that are constantly evolving and becoming harder to detect and remove.
