About CostItApp adware

It works as browser add-on that can be added to all most common web browsers, including Google Chrome, Mozilla Firefox, Internet Explorer or even Safari. This means that Apple users can get infected as well.

Once installed CostItApp will display various advertisements on all of your web browsers in all kinds of forms. Those ads usually appear when you are visiting e-commerce websites, such as eBay or Amazon. You will be offered to purchase some particular goods or services at very appealing price rate. Don’t fall for that trick and don’t click on those advertisements because you will be immediately redirected to other websites that might be owned by various cyber criminals. This way your computer can get infected with other viruses or if you attempt to purchase something there you can even get scammed and lose your hard earned money this way.

Distribution Methods of CostItApp adware

CostItApp is distributed in a malicious way called bundling. I.e. it travels bundled with other applications that can be downloaded from the Internet for free. That’s why you should always pay close attention to the installation process of freeware.

Never skip any steps and always opt out for a custom or advanced install mode if possible. This way you will be able to see all available options and make needed changes. Reading terms and conditions would be considered wise as well. Don’t rush, because some of the most important information can be displayed in a very tiny font and you don’t want to overlook that.
