Yesterday I downloaded a program called JW Video Player by accident and then I uninstalled it soon. However, since then I found my browser is going crazy. I start getting a lot of different pop-up ads on Internet Explorer. They are really annoying but I can’t find any way to get rid of them. Norton says my computer is clean and the program is not in Control Panel anymore. What should I do now?
JW Video Player is categorized as a PUP or adware that can be added on a target computer without asking for the permission from the computer owners. Usually it comes as a consequence of installing some potentially unwanted programs, PUP for short, like a toolbar or browser hijacker bundled with other freeware from the Internet. Once it gets installed on your computer, it can cause a series of annoying troubles to disturb your online usage. It can change web browser’s default home page to a particular web site without any permission and may redirect a user to a predefined site whenever the he/she enters invalid address or performs an Internet search. These unwanted changes could happen on Internet Explorer, Google Chrome, Firefox or even Safari browser.
Once compromised, your web browser will run slower and slower. It takes forever to open a web page and run a program. In addition, floods of ads will disturb your web searches and degrade your web browser performance. Most browser hijacker viruses can come bundled with freeware or other potentially unwanted programs. They usually disguise as additional add-ons or plug-ins so many inexperienced users may download them without any awareness until they find out the web browser is going crazy and out of control. So users should be careful while downloading any programs from the Internet. Also it is suggested that users should choose Custom Installation and deselect all options to install unknown applications. For the safety of computer, it is strongly recommended to uninstall malware associated with JW Video Player immediately.
