Even all of these security measures in place ,there is still a chance for things to take an ugly turn for the worst. Windows Defender will help to protect against malware infection,malicious downloads,popups,slow performances and a variety of other internet-borne threats. To help avoid virus and malware infection, it is important to take care with all the online activities.Spyware as we all know is a program that is installed on a PC without the users agreement and is directed at collecting personal/sensitive classified information about a user or the computer. So an anti spyware is a program that blocks malicious programs from fulfilling their intensions and Windows Defender is an anti spyware and is more capable. Many people use anti-spyware in combination so as to add multiple layers of security. But should a conflict resides, it is recommended to use only one solution at a time.
Unwanted software can be installed by websites, downloaded programs, or a program you might install from a CD, DVD, external hard disk, or a device. Spyware is most commonly installed through free software, such as file sharing, screen savers, or search toolbars ,some spyware can be installed from a website through an embedded script, or program in a webpage. Some unwanted software requires your help to install through web pop-ups or free software that require you to accept a downloadable file. However, if you keep Windows up to date and don’t reduce your security settings, you can minimize the chances of a spyware infection. Some websites will repeatedly display pop-ups asking you to install a toolbar or change your home page. When this happens, try closing the browser window. If the pop-ups still appear, right-click the Internet Explorer button in the taskbar at the bottom of your screen, and then click Close Group. As a last resort, close any other programs you have open, and then restart your computer. When you visit websites, do not automatically agree to download anything the site offers. If you download free software, such as file sharing programs or screen savers, read the license agreement carefully. Look for clauses where you must accept advertising and pop-ups from the company, or that the software will send certain information back to the software publisher.
