Btrll.com adware is the tool that is engaged exclusively in advertising activity. After the infection, adware begins to show ads, and performs it in all imaginable methods. Pop-up windows, suspicious links, redirections, commercial banners and the switch of the search results – this is a brief description of its techniques. Search engines do an important job: they check all the pages on the Web to let the user see only the best ones. Each page is meticulously tested, and only the most useful ones can pass this examination. Web-pages that don’t pass the test, immediately fall into the category of “untrusted”. This test is called indexing, and it takes a significant numbers of staff and resources, as thousands of sites of different grades are produced every day, and the new, sectors, pages and items emerge on the sites that are already tested. However, when the customer installs Btrll.com, he refuses the advantages of the reputable search engine, and replaces it with virus. Virus hasn’t enough resources to index the web-sites like Yahoo does. When you type something on the compromised browser, the suspicious tool just selects the most appropriate web-site of few dozen that are stored in its list, and puts it on the first place. Most often, this web-page is untrusted, and has no relation to the thing that you wanted to find. Adware shows it on the first position just because the owners of this website have signed an agreement with the web-criminals, obliging them to make a certain amount of page views. Virus isn’t interested in user’s preferences, and pays no attention to what he wants. Adware will make you see as much banners as you can, until you understand that you were tricked.

Undesired tools can infect customer’s workstation in lots of ways, in attempts to deceive the customer to let malware enter the computer. Advertising software act differently. Officially, the advertisement utilities don’t cause direct injuries to user’s machine and cannot be called “viruses”. They can drive you mad; they make the Internet browsing hard as hell, although they can’t inflict any injury to your machine and the private info. This explains, why adware is distributed fully legal. Many customers download it by themselves, from its web site. The most effective manner is the bundled installation with useful toll-free programs.
The manner of bundled penetration must be discussed severally, as it’s the most widespread cause of penetration by viruses and hijackers, as well as by all kinds of fraud browsers and extensions. This technique is easy: viral files are added to the installation file of the wanted tool. This file is completely closed, and you can’t see what you are installing. Installation is the only action that user can perform and he, in the majority of cases, does it. Thus, if victim installs the software that you looked for, virus installs too. Advertising programs are spreading in legal ways, so, they have to inform the customer about their actions, and receive the permission. When the malware isn’t inside the machine you still have a chance to avoid it. The chance is named “advanced installation”. It can be found in a separate window, during installation, where you are asked to select the installation manner between “recommended” and “difficult”. The easy technique is that you will simply install everything that is in this file, even if there will be ten totally worthless tools. If you choose the advanced method, you will see all files, prepared for the installation, and will have the opportunity to decide personally, which programs to install. In fact, it doesn’t matter how the installation methods are named – core is that the swindlers want the user to be dumb and follow their instructions. We hope that understanding the ways, which malicious programs use to infect your computer, it might help you to protect your PC.
Some visitors are asking; for what reason hackers create adware that annoy users so badly, if they can simply publish advertisements in designated areas? Actually, at its big value, legal ad brings too few customers. The deployment of any advertising on any web-site costs lots of money, and the price is increasing in direct proportion to the value of the web-site itself. Google, Yahoo and Bing provide more complex advertising techniques, but they are not as effective as adware. At the same time, this advertising on any web-site attracts no more than 10% of all visitors which have seen the advertisement. We have to point out that 10 to 1 is the incredibly great result, but ordinarily the ratio goes on tenths of a percent. Adware can redirect almost all its victims to the needed website and it will cost less. Usually, customers don’t believe that adware is harmful, until their computers are totally dead, and use those computers for years, suffering the different issues during the use of Web, and considering that it’s normal. Suchlike customers provide a permanent flow of visitors to untrusted web-sites, helping them to function for a long time.
Now, since virus is uninstalled, you should know how to avoid infection in the future. Besides the anti-viral program, there is another thing that may defend your computer and your information against viruses: it’s your own skill. Programs don’t allow mistakes, but humans do, and such failures are the only cause of adware infections. There are few rules that you should abide, if you want to keep your machine protected:
- Anti-virus is the first line of your PC’s defense, that’s why it must be decent and updated. Some malware might ask you to switch the anti-virus off. It may be performed in form of a pop-up window or in other manner. You should not abide to suchlike requests.
- Do not neglect the browser hints. Browsers have very good manners of threat finding and resistance against user’s dangerous doings. If the browser tells you about the hazard of the web-site – don’t go to this site.
- Customer should avoid performing any actions on the perilous websites. When we say “malicious”, we mean all the types of websites with X-rated content, sites of foreign exchange brokers and third-class web-sites, which distribute pirated media-files or defective goods.
- You must closely follow the installing of any tools. User agreement is too massive, and contains a bunch of useless info, but if you’ll read it – you might know something substantial. If we’re talking about the paid software, developed by prominent software vendors such as Microsoft, Skype or Adobe, you can rely on their standing. But if you are installing pirated programs in this manner, you’ll jeopardize your laptop and the files kept on it. When you install any software, it could give you the choice between a “common” and “for advanced users” type of installing – choose the “complex” variant.
- Be careful with e-mails. If you gain a message that you did not wait for, and you don’t know who send it – you should not click on it.
- Always keep important data on an external drive. If the PC is often attacked by malware, the wisest solution would be to keep the significant info on an external media that will become your backup if the computer will be heavily infected.
The rules are simple, but the fruit of adherence to them is really big. If you can add something to this item or want to get rid of a problem during the uninstalling of Btrll.com – just comment this item and we will help you as soon as possible.
