Yet, we suggest you to read it all, as the understanding of how a harmful tool works can assist you to get rid of it.

Smart Defender

Smart Defender is a dangerous tool. It’s not a good surprise, particularly if you thought that it’s a useful utility, yet it isn't an epic fail too. To start with, Smart Defender is unable to spoil your information. Also, it isn't a Trojan that calls real virus into your OS. It’s just an advertising program which shows spam in good supply. Anyway, you'd better not give it time to become worse, as in a few days it will call real problems, and in four weeks you won’t be able to work on your laptop at all. It all happens owing to the one quality of an advertising program: Smart Defender critically lowers the protection state of the infected machine. It hits your browser, which is the most vulnerable software in the system, in terms of defense from the viral threats. One of browser's tasks is deterring suspicious software every day and simultaneously letting you browse the Net. While all’s OK, you do not realize how often your browser guards your device from penetration each day. In case the browser controls get altered, though, you'll see those changes instantly.


There are red flags that can make you point out an adware before it settles in. We're going to give you such information:

  • The second disadvantage of Smart Defender is that it allows plenty of unwanted tools into the system. And they are not useful. If your system is secure, it declines all attempts of undesired utilities, yet as Smart Defender is in the system, the case gets nastier. Smart Defender alters the security settings, and in a while you can see a heap of advertising tools.
  • Useful utilities start working strange, suffer from fatal failures, close spontaneously, and so on. Such things might take place even on a healthy machine, but if it happens more frequent than 3-4 times per month – your system is infected. This might be caused either by an overall corruption of your computer by trashy programs or by conflicts between advertising tools and helpful software.
  • Pop-ups are the very annoying thing, and you’ve spotted them in the first place. You are reading our website to get rid of them. Banners are coming plentifully with Smart Defender, and the issue with them is that they are fully unsafe. Usually, they have nothing to advertise, and banners lead the user to unreliable sites where there's nothing to see besides trashy ads and, sometimes, more dangerous viruses, which may damage the OS.
  • The leading thing, which you notice if your device suffers from an infection, is that your computer launches way slower than usual. You might not have thought about it, but you know for sure how long does it take for your machine to boot, and if it takes longer – you notice it. It is so because suspicious programs prefer to load simultaneously with your AV-tool and several other system processes. Each dangerous tool that Smart Defender summons into the system acts in the same way. In the end, your machine will boot for three minutes or even more, which is totally unallowable.

If you notice any of these signs – you know what to do. Do not think twice to check your system by hand, or to install an effective antivirus and check the machine.

How Smart Defender gets into the system

Smart Defender

This is a very interesting information, as you should realize the methods of penetration to shut them down. We have just defined that adware isn't a complicated tool, which leads us to a more optimistic statement: Smart Defender doesn’t use complicated infection techniques. It can't break your OS to get in. Instead of it, Smart Defender lets you to do its job, and you take it. Advertising programs prefer a penetration method, called “sponsored installation.” Its strongest pro is that swindlers aren't doing anything, except for uploading a software bundle with adware inside it on any well-known torrent-tracker. Users gratefully do all other parts: they find a package, install it without looking into the terms and conditions and neglect the main rules of PC security. To secure your machine from such type of problem, you should begin acting more cautiously in the Net. Do not use unpaid tools from the unlicensed sites, no matter how popular and useful they look. It isn't hard to tell when a page is an official seller of some tool, as it has to have all the permissions and seals from its producer which you can see on this site. By following the given rules you’ll lower the infection rates greatly.
