To do this reboot your system and then press F8 key continuously. You will see a menu early in the ignition the PC without stopping. Choose safe mode from there and then run your antivirus. Once proper scanned checkout properly that there must be no more infection left. Update your antivirus if it is not done. Keep your firewall always on and then later on run Windows update also.

It can be worm virus or any malware. It is not easy to trace the same until you have a really good antivirus program. For that install Hijackthis and then run the same. It will scan your system for some threats and will provide you a text file. This text file will give you the list of each location and name of application which is running in the background. You can trace the same with the log file.

I have a Kapersky antivirus and my antivirus has detected this as Trojan.Win32.Qhost.bs threat. It is a trojan virus and you will need to run a good system scan for that. This virus intend to modify the host file located in % System% \ drivers \ etc \ hosts of windows. This is used to translate domain names to the ip address. The file modified with this make your system access to other servers.

I will recommend here you block all scripting languages on your computer. Also do not forget to block all their interpreters like JavaScript, Java, VBScript, etc. Web browsers offer different settings for managing the various scripting languages under the options provided to them. One of them is to completely block each scripting language. This ensure much security.

Yes that can be a better initiative for you. You must be aware that there must not be any script running form a site and the same must not work. Here also consider that you do not block it completely which can cause failure of some web pages. However, it is possible to completely block ActiveX controls that can be extremely dangerous and are rarely used except for attackers.

I have some settings for your browser which can help you out. For that first set your browser settings to routinely accept all scripts. This opens the door to infection. The second thing you have to do is systematically denied all scripts. This will close the door to many sites that will not work. Ask to be alerted. This will give you warning sings for any new script.

[Spyrus]

It is possible to assign to some settings where the browser will prompt you to run the script or not. So if you agree for the same then only it works. Some sites use various scripts on every page that can quickly become annoying - you have then the choice between refuse to see if the site works anyway, this is the case most of the time and there are only related features that become unavailable and return to the page without agreeing.
