What are you to do when you have a computer problem so bad that your computer won't start at all and you're pretty sure a virus or some other malware is to blame? How do you scan for viruses when you can't start Windows to do a virus scan?

This is where a bootable antivirus program becomes the hero of the day. Dmg for windows. 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.

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

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.

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

You can scan specific files/folders or the whole drive
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

It's difficult to use the file/folder-level scan option

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

Comodo Rescue Disk can be launched from a USB device or disc in either text-only mode or with a full graphical user interface (GUI). The GUI version has a familiar program interface which is much easier to use.

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

Can i run malwarebytes and avast together. Download Malwarebytes for Mac (the free version) and you get a 14-day trial of the premium version with automatic (real-time) virus and malware protection. After 14 days, your trial reverts to a limited disinfection scanner.

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. Visual studio 2008 express registration key generator.

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.

Dr.Web LiveDisk

What We Like

Custom options not found in some of these other bootable AV programs
Lets you define the types of files it should scan
Checks for virus definition updates from within the software
Runs from a disc or flash drive

What We Don't Like

The large setup file might take a while to download for some

Dr.Web LiveDisk is a feature-filled free bootable virus scanner for Windows and Linux.

There are plenty of configurable settings, like choosing the actions Dr.Web should take when finding infected, suspicious, or incurable files. Also, you can set what should occur in the event it detects specific issues like adware, dialers, jokes, hacktools, and riskware.

You can also exclude directories from being scanned, set how large a file can be before it's excluded from a scan, and define a maximum duration Dr.Web is allowed to spend scanning a single file.

I like that Dr.Web can check for virus definition updates directly from the program. This means you can reuse the program in the future and all you have to do is update it before you do a scan.

You can install Dr.Web LiveDisk to a USB device or a disc, but either method is still a rather large download, at over 700 MB in size.

Kaspersky Rescue Disk

What We Like

Lets you scan specific folders, the whole drive, and other areas
Scans for many types of malware
You get to choose which interface to use: graphical or text
Includes other tools

Kaspersky has what's called a Rescue Disk, which can scan for viruses, worms, Trojans, malicious tools, adware, dialers, and other malicious items.

You can pick between using the graphical mode (recommended) or the text-only mode.

Your scan options include Filele
