Install Malwarebytes Anti−Malware
Malwarebytes Anti-Malware (MBAM) is a free computer virus removal tool (that offers a premium plan, too). It is an anti-malware software that scans for, identifies the symptoms of computer virus (or malicious software), and removes different types of malicious software (adware, spyware, trojans). Also, it offers an easy-to-use interface and a short wait time for scans.
Download it from the official website, install it on your computer, click of the Scan Now button and wait for the treats to be eliminated.
MBAM also has a premium version which offers a full-time background 'Malware Protection' and Malicious Website Protection, and a shorter wait time for scans, which is not the case with the free version.
Note: Although MBAM automatically updates its database, you can also check for updates manually by clicking Update. For best results, it is recommended to install it and scan for viruses with it while you are in safe mode. If you don't know how to enter the safe mode, click here to learn more.
A browser toolbar is usually a horizontal line with shortcut icons on it that resides within a browser's window. Its primary purpose is to provide a better user experience. However, some toolbars can be harmful. Almost every computer user has come across browser toolbars that he/she didn't (want to) install showing up on the screen. They usually get installed when you install a piece of software, without your awareness or consent, and certain toolbars can make way for a virus in your computer, by redirecting you to a malicious website automatically.
Ensure to untick unwanted checkboxes during software installation
Most people don't even pay attention to the options a program installer offers. They just hit the install button and wait for the installation to be completed. What they don't know is that toolbars and other unwanted programs are most often installed along with the desired softwares people download from the Internet.
To prevent toolbars and other unwanted software from installing, select the Advanced/Custom settings field that every software installer offers and untick Install XYZ toolbar, and/or Make XYZ the default webpage.
