No matter what add-on you are eager to install, it can be the weak point for the whole system. Key Coupons is not an exception. All software vendors produce security patches and worry about the safety of their users. But if you install any browser add-on, then software companies are not able to guarantee that your PC will not be infected. Internet swindler can open the add-on like a gate to the PC. Of course there is a good effort to escape from this situation: use add-ons from popular and reliable vendors only. But is not guaranteed defense from hackers and viruses. I advise not to have browser extensions at all.
But if you still want to download one or another browser extension then be prepared that this add-on will have compliance to collect your private information that you type on different web pages and can sell it to the third parties. You should realize that to download a browser extension is the same situation that todownload software. Will you download software if its vendor is untrustworthy? I think, no. So, you also should think about the extension that you want to install.

So, you should not believe the popping-up windows and its coupons. Also you should not visit the landing pages of the demonstrated promotions for they can be viral and so, in its train, your PC will be infected with a real viral program on your computer.

Also these ways of removal are efficient, so you will get the wanted result and the browser add-on will be removed together will all its manifestations. It is also an easy technique; it yields only to the automatic method of removal. But occasionally, using this technique users notice that the program returns to the browser and they have to find any other methods to remove it.
Also there is another manual way of removal where you should remove files and registry keys and values. The method is safe if you can follow it carefully or let the specialist perform it. To make this method more secure you should do the backup of the registry. You should keep in mind that only the listed elements of the program should be enumerated and no one more otherwise the system will not load.

Speaking about the paid techniques of virus removal, I should list the Computer Repair Shop Service and paid Antivirus software.
These methods are the most effective. In spite of the great distinction in the price (Repair Shop service depends on the complication of the issue and may cost up to $300, but paid antivirus costs up to $60) these methods are almost equal in the effectiveness and in the results. I should also mention that paid antiviruses always has support service (often for free) that will solve your problem like in an expensive computer repair shop.
