Ads by 4HD on Google Chrome, Mozilla Firefox, or Microsoft Internet Explorer are caused by potentially unwanted programs (PUPs) that often infect a computer system without user knowledge. Once these unwanted programs infect a computer and attach to affected internet browsers as add-ons and extensions they will begin to access user browsing data, which is used to generate pop-up and targeted advertisements it feels users are most likely to click on.
4HD adware may be promoted as a free tool or utility to view high definition videos and other media. However, users should beware of the symptoms created by this program and others like it. Not only do they generate pop-up advertisements, but they may use collected user browsing data for different marketing campaigns via email, postage mail, and other communication outlets.
Potential 4HD malware is commonly known as the “4HD virus” even though the unwanted program is not a computer virus. However, the 4HD virus is very intrusive before and after install, it modifies existing browser and system settings (including browser and system start-up protocols), and it primarily bundles with other unwanted programs, malware, and malicious threats that can cause further issues and will also need to be removed.
