IdleCrawler is not a computer infection, but it often arrives with potential threats and unwanted applications, so chances are that you had no intention of having this botnet on your system. The main reason users utilize IdleCrawler is for it to “crawl” through websites in order to create a web index. Such botnets are often used by web developers and online marketing specialists, but it is obvious that this program is of no use for you. Hence, you need to remove IdleCrawler from your computer, and do not forget other unwanted applications while you are at it.

According to our researchers, IdleCrawler is another version of GigaClicks and WebStroller crawler. You can read more on it at However, as you can obviously see, there is no direct download link for the botnet at the official website, and you have to register to get the service. Therefore, if you see IdleCrawler running on your computer, it means it has arrived via different route. It would not be surprising because the main method of potentially unwanted software distribution is bundled downloads.

Consequently, IdleCrawler always comes bundled with third party downloaders. We have noticed that systems which had v9 browser hijacker, PastaQuotes adware, Adlucky, JollyWallet, RegOptimizer Pro, PC Optimizer Pro and other unwanted programs, had IdleCrawler running as well. The problem is that users install the aforementioned programs onto their computers willingly (albeit unknowingly). Thus, you have allowed IdleCrawler to enter your PC as well.

Luckily, the programs it comes with are more dangerous than IdleCrawler itself. It is also easy to tell that you have a botnet on your computer because IdleCrawler opens from four to six tabs instantly on your default browser. This behavior is more annoying than dangerous, but the botnet can use up your system resources and slow down your Internet connection. It is especially easy to notice when your computer is a little bit older, or you have a basic Internet connection package.

In other words, having IdleCrawler on your PC can be an annoying experience. If you want to avoid any potentially unwanted software behavior, you need to scan your computer right now and remove IdleCrawler along with all the other undesirable applications. Fortunately, it is not complicated to uninstall the botnet via Control Panel.

After manual removal, you need to consider investing in a powerful antispyware tool that would help you safeguard your system against a number of threats. Do not forget that freeware apps seldom come alone, so you will most probably have to take care of a list of other undesirable applications. Hence, getting yourself a legitimate malware detection and removal tool is always a good idea.

    I think you over simplified the removal of idle crawler. The uninstall can have problems such as "contact administrator" when you are the administrator. I find windows uninstall dosn't work with most malware. Then what do you do? Buy some expensive software?
