When your PC is infected by malware which a regular antivirus tool can't remove, then scanning the system with a bootable recovery disc can often be helpful. But which one? To find out you'll normally have to download an ISO image for each one, then burn them to separate discs - not exactly convenient.
Install SARDU, though, and your life will be rather easier. Not only does the program help you to find and download ISO images (antivirus, utilities, system recovery, Windows, Linux and more), but it'll then combine them into a single image, saving the results to a USB key or ISO file.
SARDU offers direct support for many popular images, and these are organised into various tabs. "Antivirus" has rescue discs from AVG, Avira, Bitdefender, Kaspersky and many others; "Utility" includes essentials like Parted Magic and System Rescue CD; and there are 18 Linux distros and 18 Windows PE, Recovery and other discs thrown in for good measure.
Essentially you can download these in a click or two, or grab others manually, if you prefer. The images may then be combined and saved to a USB key, or an ISO image. And if you boot from this, you'll find a simple menu which offers the various disc options you'd downloaded, and allows you to launch them with a click.
An odd and unintuitive interface means this isn't nearly as easy as it should be. And the program provides very little useful assistance or feedback to users, either, which can get frustrating when you can't figure things out. But if you have any problems, keep going, it's worth it eventually - we managed to combine 3 antivirus and 4 utility images into a single recovery environment, which itself worked very well.
Please note, SARDU attempts to install multiple toolbars and similar "extras" along with itself. If you're not interested, pay attention during setup and click the "Decline" options when they appear (which was three times for us).
While the interface is poor, SARDU's core functionality works well, and the program does a good job of combining your chosen images into a single bootable environment
