The StartJoy browser extension is promoted at Startjoy.com as the perfect tool that can allow you to turn your Web browser into 'social & media center.' The StartJoy browser extension may arrive on your PC under the name StartJoy New Tab and may be accompanied by applications like NetCoupon and WinFix Pro. Security investigators reveal that the StartJoy New Tab software is created by the infamous Imali Media Ltd. and shares many similarities with the TvNewTab and the Social Media NewTab adware. It appears that Imali Media Ltd. decided to combine two of their products into one and save on server maintenance and pay-per-install distribution. The StartJoy adware might change your homepage and search aggregator to Search.StartJoy.com and gain access to bookmarks and installed themes and record your Internet history.
The new tab by StartJoy may include to-do lists and links to Facebook, Classmates, Vkontakte and MySpace. Security investigators alert that the StartJoy New Tab adware may bring up a dialog box on your screen and ask to post advertisements via your social media profile on your behalf. The StartJoy New Tab adware may use JavaScript to add panels to your browser interface and load ads on the left and right side of your screen. The ads by StartJoy may include links to products on Amazon, Best Buy and Aliexpress. Users shouldn't buy items that are associated with the StartJoy New Tab adware to avoid being involved in a financial hoax. The search engine at Search.StartJoy.com may feature links to Virustotal.com and Speedtest.net, but the StartJoy adware is not recognized as a legitimate application. The StartJoy adware may compromise the security of Web browsers that run on the Gecko, WebKit and Trident rendering engines. You should not tolerate the activity of the StartJoy adware and reclaim your browser by using a reliable anti-spyware instrument.
