The AddToThis software could arrive on your PC as a drive-by installation of freeware via the 'Express' or 'Typical' option. The AddToThis software is promoted as a helpful shopping companion that can deliver you exclusive deals and discounts and many users may be interested to install it. However, you might want to know that security researchers classify AddToThis as adware because it is designed to flood the user's web browser with marketing materials. The AddToThis adware might present you with pop-up and pop-under windows with special offers, banners, ad boxes and in-text hyperlinks to sponsored services. Moreover, the AddToThis adware can use tracking cookies and record your search terms on Google to conduct behavioral marketing. The AddToThis adware functions similarly to AllSaver and BuyNSave and may use a browser plug-in and an extension to perform its operations. Additionally, the AddToThis adware may replace the safe ads on trusted online stores like Amazon and eBay with links to low-quality shops and insecure Internet resources. Therefore, users might want to install a trustworthy anti-spyware application to secure their web browsers and eradicate the AddToThis adware.
