Remove PUP.Optional.BundleInstaller.A (Removal Guide)

PUP.Optional.BundleInstaller.A is a heuristic detection used by several 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.

PUP.Optional.BundleInstaller.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 PUP.Optional.BundleInstaller.A was installed during the software setup process.

PUP.Optional.BundleInstaller.A is an adware program, that displays pop-up ads and advertisements on web pages that you visit. These advertisements will be shown as boxes containing various coupons that are available, as underlined keywords, pop-up ads or advertising banners.
These ads are aimed to promote the installation of additional questionable content including web browser toolbars, optimization utilities and other products, all so the PUP.Optional.BundleInstaller.A publisher can generate pay-per-click revenue.
When infected with PUP.Optional.BundleInstaller.A the 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 PUP.Optional.BundleInstaller.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.
