What is Koala Personal Search?

Koala Personal Search is a popular browser add-on that has a lot of advantages and users often download and use it willingly. You may do it as well if you find it's service useful. You can see an extract from its official site that describes the application in details:

Once installed, Koala is conveniently accessed right from your browser toolbar and provides one search tab for all your personal content. Simply enter a keyword and Koala will retrieve and display relevant results from your personal accounts or favorite websites. Koala is there for you right when you need it! When searching the web with Google or Bing, Koala will show relevant search results from your personal accounts, with a convenient interface to browse through them, right from your search results page. Koala uses secure Open Authorization links to connect to your personal accounts and does not access or store your passwords. You decide which accounts to connect and can easily disconnect accounts at any time.”

In fact, this program fulfills its promises. Once inside it starts working on Google Chrome, Mozilla Firefox or Internet Explorer, drops a search tab and implements other promised activities. However, recently we have received various complaints from the users that Koala Personal Search has infiltrated their computer without them being aware of it and started displaying 'Koala Personal Search Ads' when browsing. Due to this it associated with an adware and potentially unwanted program (PUP) and you should remove it if it appeared on your computer out of nowhere. Otherwise, you may experience redirects to questionable websites. That's because probably 'Ads by Koala Personal Search' are managed by third parties that seek to increase revenue by tricking you into clicking on those ads and redirecting to affiliate websites. Besides, think about the security of your privacy. Be aware that this add-on is able to access you personal information. We recommend not using this program if it got insides bundled with other software, because this way other third parties may access your personal information via Koala Personal Search and you may end-up with serious privacy-related issues.

How can Koala Personal Search Hijack my computer?

It is very likely that you will notice 'Koala Personal Search Ads' on your web browser right after installing another freeware or shareware. Even if you like the service, we recommend removing it if it infiltrated the system without your permission asked. Instead, you may look for its official site and install it there. Commonly this browser plug-in infiltrates user's computer with such programs as download managers, PDF creators, or video streaming software. Therefore, you have to be careful not only when choosing and downloading free programs, but also when installing them. Even if you are not fond of reading those long lines, it is advisable reading End-User License Agreement. Moreover, it is very important to select Advanced or Custom installation option because this option allows to monitor all installation option and discloses all additional components that were about to instal. Never accept to install unfamiliar programs, such as add-ons, toolbars, plug-ins or extensions. In case it is too late and you have installed one and it appeared to be Koala Personal Search, look for it on Add/Remove programs folder and remove once detected.
