I run Firefox version 36.0.4. I have started to experience intrusive pop-ups and automatically opening advertising web pages. When I open my default webpage (google.uk) and search for a topic I get a slightly modified Google search results page which is subtly different to my normal page. At the top of the search results it says results provided by 'Ads by coupons and fun'."
Daily Offer Service has something to do with Coupons and Fun
Daily Offer Service is classified as an adware which can bring users lots of unwanted ads after the infection. Mainly, it uses ads to generate pay-per-click revenue. Daily Offer Service is powered by Coupons and Fun. So if your PC has been infected by the adware, you may see ads with names like "Ads by coupons and fun". Commonly, you may get this adware through free downloads. If you click its ad, the ad can redirect you to some dubious websites and cause viruses or malware infection. And its ads are compatible with almost all brands of browsers including Internet Explorer, Mozilla Firefox, Yahoo, Bing, Opera and Safari. You should not take the adware slightly.
