Ads by DiscountRatio is a type of Adware virus and it operates in a way typical to that family of viruses. Whenever you start a browser page you will receive a large dose of unwanted Ads. Specialist consider Adware to be the least dangerous virus type and that’s mostly true – at least as long as you abstain from clicking on the ads. Ignoring them can get incredibly annoying over time, but this is not the only reason why you want to remove this virus asap. Interacting with the Ads will put your computer into a real danger, as the Ads are often the back door for other more sinister viruses.

Listing some of the dangers about interacting with the Ads

First of all you have to realize that all offers you might see on the Ads are a fraud. This is characteristic to all Adware viruses and Ads by DiscountRatio is no exception to the general rule. Viruses like this will try every trick in the book to appear to be  selling real products. The sites they link to might even look like the legitimate seller of the stuff. Site design and UI are ripped of and you might even see a very similar URL, that has but one or two different characters in difference. Spotting such a difference is very hard unless you are actively searching for it.

Buying anything from these Ads would be a foolish act as none of the things offered by Ads by DiscountRatio are real. You’ll either end up with a program that will ultimately not work. It might have the gall to ask for more money before functioning though. Alternatively you’ll end up with an infected installer, which if run will land another virus on your computer with new schemes to rob you.

Some Ads might be camouflaged as system messages

Years of TV commercials and billboard exposure has rendered most of us fairly resistant to offers from Ads. Because of this virus developers have started to explore additional methods to fool us with their tricks. The following scam revolves around messages that appear to be generated by your system. Generally at first you’ll get some kind of warning or error. It will claim some kind of problem with your computer – possibly a missing plug-in, required update or issues found. The aim is to create a sense of unease, urgency or even panic in you. You are then offered a solution to this non-existing problem – a file containing a virus. Most often this is some program that does absolutely nothing, but it will promise to “fix” the issue if you pay a sum of money to “activate” it. REMEMBER! This trick is not exclusive to Ads by DiscountRatio . This is a very popular trick and it will be utilized by many Adware viruses or infected sites. Pay attention!
