Remove Adware:Win32/Baidu.A virus (Removal guide)

Adware:Win32/Baidu.A is a specific detection used by AVG Antivirus, Avast Antivirus, ESET Antivirus, Microsoft Security Essentials and other antivirus products to indicate and detect a Potentially Unwanted Program.
A potentially unwanted application is a program that contains adware, installs toolbars or has other unclear objectives.

Adware:Win32/Baidu.A got on your computer after you have installed a freeware software (video recording/streaming, download-managers or PDF creators) that had bundled into their installation this browser hijacker. This Potentially Unwanted Program is also bundled within the custom installer on many download sites (examples: CNET, Brothersoft or Softonic), so if you have downloaded a software from these websites, chances are that Adware:Win32/Baidu.A was installed during the software setup process.

Adware:Win32/Baidu.A is an ad-supported extension for Internet Explorer, Firefox and Chrome, and distributed through various monetization platforms during installation. When installed, the Adware:Win32/Baidu.A browser extension will display advertising banners, pop-up advertisements and in-text ads.
Other common symptoms include:

• Advertising banners are injected with the web pages that you are visiting.
• Random web page text is turned into hyperlinks.
• Browser popups appear which recommend fake updates or other software.
• Other unwanted adware programs might get installed without the user’s knowledge.

You should always pay attention when installing software because often, a software installer includes optional installs, such as this Adware:Win32/Baidu.A browser hijacker. Be very careful what you agree to install.
Always opt for the custom installation and deselect anything that is not familiar, especially optional software that you never wanted to download and install in the first place. It goes without saying that you should not install software that you don’t trust.
