to send offline Web sites and to send spam to the world, cyber criminals use of networks called botnets , made from zombie computers , or computer online infected with a virus and managed outside the user's knowledge.
Botnets are are one of the largest sources of illegal income on the Internet.
The question that everyone should take when reading the newspapers or on blogs about the existence of computer botnets is, but it's not that my computer is part of this network and is used by hackers to launch attacks around the world?
To check that your computer is part of a botnet , and thus has no body in a program or process that gives access to hackers, there are different programs.
In general terms it must be said that the virus does not mean necessarily that you find this kind of virus.
For this reason, some companies have recently developed software to scan for suspicious items that can be traced back to the botnet.
The protection-botnet Centre was launched in Germany in order to minimize the number of zombie computers and displays the instructions for removing the threat from botnet computers , in collaboration with leading security companies: Avira, Kaspersky and Symantec (Norton) .
The basic rules to make sure that your PC is safe from this illegal and criminal networks are:
1) Check the computer with a scan through the program DE-Cleaner to eliminate all threats.
2) Install the service packs and updates for Windows security.
3) Install an antivirus and update it regularly.
4) Use a firewall program or the Windows firewall or connect through a router.
Regarding item one, this program DE-Cleaner is distributed in three versions differ from Avira, Kaspersky and Norton .
On the site botfrei.de are the download links for the three scanner and you can choose which one to download and use on your computer.
DE-Cleaner is an on-demand virus scanner that can be installed or used in portable version.
Operation is simple because just start scanning and wait until the end of the audit which will highlight the threats.
Even though this program, for now, only in German (DE-Cleaner Avira least I tried), there are many options so you can guess that the only thing to do is to start scanning your computer.
Talking about Avira DE-Cleaner , suffice it to say that the link USB-Gerät kopieren need to copy the scanner on a USB stick.
The check box " Vollständige durchführen Systemprüfung "if enabled, allows you to make a complete control of the computer instead of scanning directories and important files.
Starten Suchlauf starts scanning the computer.
E 'possible to cancel the scan at any time by simply clicking on the button Abbrechen .
The scan window shows the number of potentially dangerous objects that were found during the scan.
To remove all you need to click on " Alle entfernen” .
Of course, before deleting all files dangerous, you better look at the details so as not to delete things in fact perfectly safe.
Better to be cautious in using these DE-Cleaner Avira, Norton and Kaspersky if you find any files that are dangerous or infected email messages can always be false positives.
Avira DE-Cleaner and other work on any version of Windows 32-bit and 64 bit.
If you want an extra safety and if it was felt their computer to the botnet risk, you can download and install a tool for Trend Micro , called RUBotted , a program designed to remove threats and files that can turn a computer into a zombie , which is used by ' External illegal activities.
It is not just a scanner but a monitoring program of the computer that alerts you when your computer is infected, in real time.
RUBotted is fairly light, easy to use and runs quietly, protecting your computer without being detected.
At least one scan with the Norton Power Eraser would do anyway, even if there were no signs of virus because it appears to be relatively reliable.
Last night, leave your computer on and you start scanning.
