The free version is great. You install it and run a scan. When the scan has completed, you will now be presented with a screen showing you any malware infections that Malwarebytes’ Anti-Malware has detected. To remove the malicious programs that Malwarebytes Anti-malware has found, click on the “Quarantine All” button, and then click on the “Apply Now” button. Malwarebytes Anti-Malware will now quarantine all the malicious files and registry keys that it has found. When removing the files, Malwarebytes Anti-Malware may require a reboot in order to remove some of them. If it displays a message stating that it needs to reboot your computer, please allow it to do so.
HitmanPro is a second opinion scanner, designed to rescue your computer from malware (viruses, trojans, rootkits, etc.) that have infected your computer despite all the security measures you have taken (such as anti-virus software, firewalls, etc.). HitmanPro is designed to work alongside existing security programs without any conflicts. It scans the computer quickly (less than 5 minutes) and does not slow down the computer.
Once these two programs are run your computer should be free of the malware infections. If your current anti-virus solution let this infection through, you may want to consider purchasing the Premium version of Malwarebytes Anti-Malware to protect against these types of threats in the future, and perform regular computer scans with HitmanPro.
