Koala Personal Search Ads

What is Koala Personal Search?

Developed by Skyter Technologies Ltd, Koala Personal Search is a potentially unwanted program (PUP) claiming to enhance the Internet browsing experience by aggregating search results from personal accounts such as Facebook and Gmail.

Although this is a useful and popular browser plug-in, some computer users report that they observe ads by Koala Personal Search and that they did not willingly install this plug-in.

Note that Koala Personal Search is not related to malware or virus infections and is a legitimate browser add-on, however, this plug-in may be installed inadvertently without users' consent when 'bundled' with free software downloaded from the Internet. Despite this, Koala Personal Search plug-in installation is not caused by malicious software.

To avoid installation of unwanted browser add-ons, express caution when installing free software or free browser plug-ins. Developers of free software commonly bundle their programs and extensions with additional browser add-ons in order to monetize their freeware downloads.

Each time you install free software downloaded from the Internet, closely inspect each installation step for any clues that your Internet browser homepage and default search engine settings may be changed, or that additional browser add-ons will be installed.

Koala Personal Search is similar to other potentially unwanted applications that infiltrate Internet browsers (Internet Explorer, Google Chrome, and Mozilla Firefox) using the deceptive software marketing method, bundling. Examples include eDeals, SurfShield, IneedSpeed, and DonutQuotes among many others.

Applications or browser add-ons that install together with free software often add no real value for the user, and moreover, they commonly generate intrusive online ads (in the case of Koala Personal Search, users may experience 'Ads by Koala Personal Search', 'Koala Shopper', and other unwanted ads while browsing the Internet).

To avoid installation of these browser plug-ins, be attentive when downloading free software. If your download is managed by a 'download client', opt-out of installation of any advertised (bundled) browser extensions by clicking the 'decline' button.

The Koala Personal Search browser add-on is not a virus or malware, and therefore, if you have installed it willingly, you need take no further action. If, however, this browser extension was installed without consent, use the removal guide provided to eliminate it.
