DealPly is a shady browser plugin that once installed starts to exercise the characteristics of adware. The ads it generates will appear constantly interrupting you from browsing. They will emerge suddenly and prevent you from page viewing until you close or click it. The pop-ups may differ in appearance - from selling goods with greats discounts to warnings about system vulnerabilities. Since every click initiates forwarding to the sites that DealPly promotes and by this gains revenue, it is interested in making people clicking the ads.
