BasicScan is a search engine that, when installed, takes over your Internet browser's default search settings and providers. Most recent Internet browsers allow you to carry out online searches directly from the address bar. They will usually carry out that search with one of the premier online search engines, such as Google or Bing. However, if the BasicScan add-on is installed on your computer system, all these kinds of online searches are carried out at BasicScan's website, BasicScan.com. This is unfortunate because BasicScan is not designed to return legitimate search results. Rather, BasicScan is designed to return irrelevant results that are actually sponsored links. This website is designed to deliver a stream of spam and advertisements in order to profit from advertisement impressions and pay-per-click schemes.

BasicScan Overstays Its Welcome on Your Computer
While BasicScan will often not show up as a virus or malware infection on an anti-malware scanner, this browser add-on uses various techniques that are closely linked to malware, rather than to legitimate search add-ons. Many computer users have reported problems removing BasicScan and undoing its harmful changes to their computers' settings. Most computer users that have installed BasicScan on their computer acquired it as a free bundle with various freeware applications – typically video or audio players and audio and video file converters. ESG security researchers strongly advise against downloading freeware applications that require you to install BasicScan on your Internet browser. There are usually better alternatives that do not force their users to install potentially harmful software on their system. BasicScan will usually be an unwanted presence on any computer in which BasicScan resides. This browser add-on interferes with normal online tasks and may be able to record your online activity and keep track of the sites you visit. The kinds of search results displayed for a BasicScan online search will usually include shady websites like dodgy online casinos and pharmacies or websites promoting fake security programs. Because of this, removal of BasicScan should be followed with a full, in-depth scan of your hard drives with a trusted anti-malware scanner.
