What is ContradeAdder?

ContradeAdder is promoted as a browser add-on that is supposed to help people save time and money by keeping them informed about the lowest prices, best deals, discounts and similar shopping related issues. Nevertheless, it’s one of those apps that should not be trusted. It seems that the information delivered by this add-on is predetermined/sponsored, which means that its main purpose is to make money from gullible people by promoting third-party websites. In order to do that, tons of ContradeAdder ads may be delivered to you every time you browse the net. Of course, from the first glimpse those advertisements may appear to be useful; however, we are pretty sure that you can find more reliable websites and much lower prices that ‘Ads by ContradeAdder’ offer to you. Besides, don’t forget that they are prepared by third parties, not by the developers of the adware; therefore, it’s very likely that some of the advertisements may be questionable or even unsafe. In order to prevent ContradeAdder redirects that may pose a risk to your cyber security, you should ignore all ads delivered by this adware and get rid of it as soon as possible.

By the way, we haven’t mentioned yet that this add-on usually spreads via software bundles that may consist from two to tens of potentially unwanted programs. Therefore, if you have installed this adware via another freeware, you should also check whether other PUPs, such as Fast Free Converter, DragonCoupon, ShopperMaster, etc. are hiding in your machine or not. Due to such distribution technique, ContradeAdder has also been attributed to the list of potentially unwanted programs (PUPs). To conclude, keep in mind such add-ons are usually capable of tracking users, using Internet connection for suspicious purposes (e.g. download updates or other PUPs), slowing down PC’s performance, affecting security system and so on. Therefore, if you want to maintain your computer’s security and performance, you should avoid installing suspicious apps and stay away from the places where they may be promoted. In case ContradeAdder add-on is already working on your machine, we recommend to check it with a legitimate anti-malware, such as Reimage (Windows OS) or Webroot SecureAnywhere AntiVirus (Mac OS X).

How can ContradeAdder hijack my computer?

If you want to keep your computer away from various PUPs, including ContradeAdder virus, you should stop visiting illegal and really suspicious websites. However, that’s not enough because popular third-party websites (soft32.com, cnet.com, softonic.com, download.com, etc.) are also actively involved in the distribution of adwares, browser hijackers, and other PUPs. In fact, unwanted programs are seldom distributed as individual tools. More frequently, they are attached to other freewares, such as download managers or media players, as additional components. Thus, whenever you decide to install a freeware, you have to make sure whether it contains ‘attachments’ by selecting Advanced/Custom installation and following the entire installation process step-by-step. If you find an offer to install ContradeAdder plug-in, unmark ticks marked alongside it.
