This is where a bootable antivirus program becomes the hero of the day. With a bootable virus scanner, you create a special flash drive or CD/DVD disc from a working computer and then use it on the infected machine to scan the hard drive for viruses — all without needing to start Windows!

Since the most serious of viruses cause damage to the parts of your computer that allow it to start, a bootable antivirus tool can often be a powerful weapon at your disposal for getting the virus removed and your computer back up and running.

In general, getting a bootable antivirus program up and running requires that you take the ISO image provided and then, from a working computer, burn it to a disc or burn it to a USB drive. Next, you'll need to boot from the disc or boot from the flash drive on the infected PC. More details are available in our reviews and on the bootable AV program websites.

Anvi Rescue Disk

What We Like

Really easy to use
Lets you scan the whole drive or certain folders only
Can run a quick or full scan
Able to repair malicious changes made to the registry
Relatively small download size

Our Review of Anvi Rescue Disk

Anvi Rescue Disk is a really simple bootable virus scanner. There are only three main scan buttons, two sections to the program, and no custom settings.

You can run a quick smart scan, a full system scan, or a custom scan to search for malware inside one or more specific folders.

Mac books for 2018. There's also a section for finding and correcting corrupt registry issues that may have been altered by a virus.

The only thing I don't like about Anvi Rescue Disk is that you must scan the whole drive at once — you can not choose to scan single, specific files like you can with regular antivirus software.

AVG Rescue CD

What We Like

Scans things most bootable AV programs do not
Lets you check for viruses on any attached hard drive
Includes other tools like a hard drive tester

What We Don't Like

Doesn't have a graphical interface like most programs, so it might be hard to use if you're not used to that type of UI
Doesn't offer definition updates

AVG Rescue CD is a text-only free bootable antivirus program. It can check for potentially unwanted programs, scan cookies, find hidden file extensions, and even scan inside archives.

Before you start a scan with AVG Rescue CD, you have the option to just scan a folder of your choice, just the boot sector, only the registry, or any locally attached hard drive.

Unfortunately, because AVG Rescue CD doesn't provide a graphical interface, navigating the menus can become difficult.

AVG no longer updates or maintains this program, so the virus definitions will forever be outdated. You can still scan normally, but it won't catch brand new threats.

Avira Rescue System

What We Like

Updates its definitions automatically before scans
Uses a regular, graphical interface instead of text only
Easier to install than some bootable antivirus programs
Includes other tools you might like

What We Don't Like

Scans a whole partition at once without the option to check particular files only
Large download size

Avira Rescue System is a free bootable antivirus program that also functions as a registry editor, web browser, and more, all under a standard graphical interface.

Avira Rescue System automatically updates its definitions before performing a scan, which is great so you don't have to re-download the software every time you wish to use it.

During a virus scan, compressed files are unpacked and scanned for added protection.

Avira Rescue System doesn't let you scan individual files, but only a whole partition at once, which is too bad. Also, the download is rather large at over 650 MB.

Comodo Rescue Disk

What We Like

Includes an option to skip scanning certain files
Supports multiple scan types based on what you want to scan
Lets you pick between a graphical UI and one that's text only
Checks for updates automatically
Relatively small download size

What We Don't Like

In addition to the regular, installable Comodo Antivirus software, Comodo also has a free bootable antivirus program.

There are three different scan types you can start with Comodo Rescue Disk: smart scan, full scan, or custom scan.

Smart scan checks for viruses and rootkits in the memory, boot sectors, autorun entries, and other areas like the registry and system folder. A custom scan lets you choose individual files and folders to scan instead of an entire drive.

You can also scan archives, enable heuristics scanning, and skip files over a specified size.

I love that Comodo Rescue Disk includes a familiar Desktop-like interface because it makes it easier to use than some of these other text-based scanning tools.
