What is QS?

QS is promoted as a free web shopping utility that can show you website rankings and will provide you with coupons and details relative to your internet searches and currently viewed content.

Potential QS malware generates deceptive and intrusive pop-up ads across Chrome, Firefox, Internet Explorer, and Safari. Ads by QS  are defined as ‘targeted’ ads because they use your personal browsing information (including all your data on the websites you visit) to produce advertisements it feels you are most likely to click on. The adware basically ‘targets’ you based off your current and past browsing habits.

QS adware is not technically defined as a computer virus but this adware is still a threat to your privacy and can be the sign of a severe malware infection. The internet security community strongly recommends that you remove QS if you find it installed on your machine or attached to your internet browser as a browser add-on or extension and use reputable Antivirus or Anti-Malware software to eradicate any existing malicious files.

How did QS get on my computer?

QS and programs like it are usually contracted without knowledge. QS is often bundled inside third-party software downloaders and bundlers. It may arrive on a computer system once other programs have been introduced to the machine. Software that QS adware may bundle with includes freeware, shareware, and dubious torrent files.
