What is Dealster?

If your browser is constantly showing you suspicious 'ads by Dealster' and other commercial messages, it might be that Dealster add-on is hiding in your computer. This program is promoted as a money saving tool that scans online websites and shows people special offers and coupons. However, this application has already been labeled as an adware or potentially unwanted program (PUP) because it performs not only these, previously mentioned, tasks. It may also start disrupting your browsing sessions, may lead you to suspicious websites or may try to take over your personal information. Dealster is compatible with all popular browsers, including Google Chrome, Mozilla Firefox and Internet Explorer, so you may see its ads once you open any of these browsers. Before you start believing that this program seeks to help you save the money, remember that its ads may be employed by third parties in order to drive traffic to their websites and gain the profit. Of course, we can't assure you that you won't be redirected to some phishing website, which spreads insecure programs or displays unsafe links… In addition, if you would read Dealster's End-user license agreement, you would notice that its owners do not accept any responsibility for these third party ads.. Besides, privacy policy section reveals that as soon as Dealster is installed on the system, it starts tracking its user and accumulating data related to his/hers browsing habits. So, you can never be sure that your personal information is safe and won't be sent to bad guys. That's why we highly recommend you to eliminate this untrustworthy program from the system.

How can Dealster hijack my computer?

As we have already mentioned, Dealster is compatible with every web browser that is installed on the system, so it's really hard not to notice its infiltration. No matter that it is not a virus, Dealster and other adwares may get inside your computer unnoticed and without asking your approval. It means that the prevention of this adware (or potentially unwanted program) is on your own hands. Typically Dealster is distributed along with free software, which was bundled with third party supported programs. Therefore, if you prefer quick installation and choose Recommended installation option, it is very likely that you will automatically give permission to various plug-ins, add-ons, extensions and so on. If you want to avoid ads and do not want to be redirected to suspicious websites, you should take the installation process of the freeware more serious. Usually in the beginning of installation process, you are asked to choose between Advanced/Custom or Quick/Basic installation. It is always advisable to choose Advanced/Custom installation option that allows you to fallow the entire installation process. If you notice any kind of proposition to modify your browser in any way or install any king of 'additional' software, you should decline this offer and avoid installation of Dealster or similar add-on/extension/plugin. If you are already suffering from intrusive Dealster redirects and ads, do not waist your time and get rid of this intruder without hesitation.
