Do you notice that your computer suddenly crawls for some reason you can not explain? It could be nothing, but it could be (Bot Net) that your computer is busy with other things. Among these, it is the hacker attack that has made the computer part or slave of a bot.
"How can this happen; Do I use anti-virus software constantly to this day? ”
The software used by the Bots is clean and is usually installed on the victim's computer by the victim himself / herself, who has been deceived in some way. The software could appear as a legitimate product claiming to be an anti-virus scanner when in fact it is malicious Scareware. Once installed, a "door" opens on your system from where malware developers can install rootkits and applications that allow bot networks.
Bot net software effectively puts your computer at the disposal of the hacker. It works "normally" and waits to receive instructions from a master control terminal controlled by the bot net owner who is usually a criminal.
The computer contamination system, ie those who only deal with hack systems, earn enough money by selling the rights of managing the infected computer to owners Bot Net.
Well read, an infected computer can be "sold" without the permission of its owner.
A typical bot can consist of tens of thousands of computers that are all controlled by a command and control terminal. Hackers use bot nets because they allow them to combine the computing power and network of all infected computers to attack a single target. You know the distributed Denial of Service (DDoS) attacks.
These attacks are very strong, and the target of the attack may not be able to manage the network and the resources of a Bot Net which may also contain 20.000 computers.
Some of the criminals, having such a "weapon" in their hands, also carry out blackmail to stop the attacks. Some companies (although it is a wrong policy) pay to have access to their systems again.
How do Bot Nets become so big?
Developers who create bots can have net tax-free earnings. Many times they pay 250 or more for 1000 infected computers that can be enslaved by a bot. Of course the bad guys will use all the tools needed to trick unsuspecting users and install crapware. Via spam e-mails, or malicious links from forums and various other malicious websites, or anything else they can think of to get the victim to do click in the malware installer.
How can we stop hackers from slave our computer?
1. Install a special scanner malware
The program you use for viruses can be awesome, but it's not as good at finding Scareware, malware, rootkits, and other malware. Think of something like this Malwarebytes which is known for finding malware that is often not "seen" by traditional antivirus programs.
2. Watch out for some fake anti-virus
In your search for a malware protection program you could end up installing something malicious if you do not cross out the first view you read somewhere. Never install anything sent to you e-mail or from one pop-up window.
3. Make it back up to your CLEAN system.
