If you have a standard antivirus product installed in your PC then chances are that it will stop the infection before it can spread around various files and slowly takes over the control of the entire computer. But sometimes newer variants of the malware could slip under the protection provided by your antivirus and take hold of your PC in such a stubborn way that it becomes very difficult to remove the malware from within Windows itself. In those situations, you must boot into safe mode or use Linux to disinfect your PC.
Fortunately, you do not have to install Ubuntu Linux altogether just to take care of a few stubborn malware (although in the long run it is a good idea to keep Ubuntu Linux installed in the dual boot mode with Windows). Instead, you can use the Dr.Web LiveUSB disk to quickly boot into the Dr.Web LiveDisk and remove the infections.
Dr.Web LiveUSB is essentially Dr.Web LiveDisk, only it used USB flash disks instead of the usual CD/DVD media. For this, you would need a flash disk with a capacity of at least 4GB. You have to download the nearly 650 MB file from the Dr.Web servers. As you launch the drweb-livedisk-900-usb.exe file, it will ask you to choose one of the USB flash disks attached to your PC. You can decide to format the disk, but it is not necessary. Clicking on the Generate Dr.Web LiveUSB button will initiate the bootable USB creation.
After the disk is ready, you can use it to boot into the Dr.Web LiveDisk which is based on the Linux OS. It boots into Linux with some basic applications pre-installed like Firefox and Midnight Commander etc. The Dr.Web virus scanner runs automatically and you can use it to scan and remove all the malware from your PC. If you know what you are doing, you can also use Midnight Commander to remove some of the suspicious or malicious files.
Conclusion: Dr.Web LiveUSB can prove to be your PC’s lifeline when all the other efforts to remove the malware have failed. It created a re-usable bootable USB disk that can help you remove the malware from any PC using the Dr.Web antivirus engine.
