If your computer is infected with malware, running an antivirus within Windows may not be enough to remove it. If your computer has a rootkit, the malware may be able to hide itself from your antivirus software.

This is where bootable antivirus solutions come in. They can clean malware from outside the infected Windows system, so the malware won’t be running and interfering with the clean-up process.

Standard antivirus software runs within Windows. If your computer is infected with malware, the antivirus software will have to do battle with the malware. Antivirus software will try to stop the malware and remove it, while the malware will attempt to defend itself and shut down the antivirus. For really nasty malware, your antivirus software may not be able to fully remove it from within Windows.

Rootkits, a type of malware that hides itself, can be even trickier. A rootkit could load at boot time before other Windows components and prevent Windows from seeing it, hide its processes from the task manager, and even trick antivirus applications into believing that the rootkit isn’t running.

The problem here is that the malware and antivirus are both running on the computer at the same time. The antivirus is attempting to fight the malware on its home turf — the malware can put up a fight.

Why You Should Use an Antivirus Boot Disc

Antivirus boot discs deal with this by approaching the malware from outside Windows. Boot your computer from a CD or USB drive containing the antivirus and it loads a specialized operating system from the disc. Even if your Windows installation is completely infected with malware, the special operating system won’t have any malware running within it.

This means the antivirus program can work on the Windows installation from outside. The malware won’t be running while the antivirus tries to remove it, so the antivirus can methodically locate and remove the harmful software without it interfering.

Any rootkits won’t be able to set up the tricks they use at Windows boot time to hide themselves from the rest of the operating system. The antivirus will be able to see the rootkits and remove them.

It does not prevent saving of infected files (doing so could lead to irreversible data loss), it just detects them. • Mail Shield: The Mail Shield monitors and filters all POP3 and IMAP traffic coming from mail servers on the internet. Avast vps 170222 for mac.

These tools are often referred to as “rescue disks.” They’re meant to be used when you need to rescue a hopelessly infected system.

Bootable Antivirus Options

As with any type of antivirus software, you have quite a few options. Many antivirus companies offer bootable antivirus systems based on their antivirus software. These tools are generally free, even when they’re offered by companies that specialized in paid antivirus solutions. Here are a few good options:

When we started to download our zip file of malware samples, Avast quickly moved the entire folder to the Virus Chest, Avast’s name for its quarantine folder. This is impressive since most Mac antivirus software we tested stopped each individual file either during or right after they downloaded and only after the zip file was opened.

• avast! Rescue Disk – We like avast! for offering a capable free antivirus with good detection rates in independent tests. avast! now offers the ability to create an antivirus boot disc or USB drive. Just navigate to the Tools -> Rescue Disk option in the avast! desktop application to create bootable media.
• BitDefender Rescue CD – BitDefender always seems to receive good scores in independent tests, and the BitDefender Rescue CD offers the same antivirus engine in the form of a bootable disc.
• Kaspersky Rescue Disk – Kaspersky also receives good scores in independent tests and offers its own antivirus boot disc.

These are just a handful of options. If you prefer another antivirus for some reason — Comodo, Norton, Avira, ESET, or almost any other antivirus product — you’ll probably find that it offers its own system rescue disk.

How to Use an Antivirus Boot Disc

Using an antivirus boot disc or USB drive is actually pretty simple. You’ll just need to find the antivirus boot disc you want to use and burn it to disc or install it on a USB drive. You can do this part on any computer, so you can create antivirus boot media on a clean computer and then take it to an infected computer.

Insert the boot media into the infected computer and then reboot. The computer should boot from the removable media and load the secure antivirus environment. (If it doesn’t, you may need to change the boot order in your BIOS or UEFI firmware.) You can then follow the instructions on your screen to scan your Windows system for malware and remove it. No malware will be running in the background while you do this.

Antivirus boot discs are useful because they allow you to detect and clean malware infections from outside an infected operating system. If the operating system is severely infected, it may not be possible to remove — or even detect — all the malware from within it.
