What is a Bootable Antivirus & the Best Tools Available

A Bootable Antivirus is a program that can be used directly from a flash drive or any disk without having to start the infected operating system at all. Sometimes, as it so happens, the operating system gets affected by a virus in such a way that the computer uses it to boot, or it simply becomes risky to do so. A powerful tool like this at your disposal can scan the hard drive for all viruses and malware without having to start Windows.

Normally, to use a Bootable Antivirus, all you have to do is to take an ISO image of the program from a computer that is working, burn it to a disc or simply copy it to a USB drive. Next, you will need to set the boot priority option in the BIOS menu in such a way that the computer recognizes either the USB drive or CD/DVD drive at first, and not the primary hard disk.

If you have ever faced any such problem where a solution was nowhere close to being found, we have compiled a list of top 10 Antivirus tools that you can use to fix your malfunctioning system.

When your PC is at the risk of severe malfunction if it is booted up, then one of the tools above can save the day.

    Hello!

    First, sorry for my poor English… it’s not my native language…

    I use to repair PCs solving everyday troubles: viruses, boot fails, freeze, internet connection, slowing and so on…
    So I always keep in my pocket my multiboot usb drives I built using both Yumi and Easy2Boot: I included rescue tools like UBCD, Clonezilla, SysrescueCD, Boot Repair Disk, Rescatux, MiniTool Partition Wizard, Gparted, free versions of several Paragon, EaseUS and AOMEI tools and many, many others. I included some bootable AV tools, of course: Avira, Kaspersky, Dr. Web, Eset and Bitdefender. Bitdefender is really cool but, first, it boots only if you put it in a single tool USB using Rufus, or, if you use a multiboot like me, on Easy2Boot, since Yumi doesn’t support it anymore.
    Second, Bitdefender Rescue CD doesn’t support some WiFi cards, so you have to use a cable to update before you scan. Also with Kaspersky and Comodo I experienced some problem with wifi on some PC.

    On the other hand, Dr. Web, Eset and Avira works perfectly on all the PC I tested (I’m talking about wifi). But if you can connect (eth or wifi) all this tools work like a charm: a friend of mine was infected by the so called “fake police virus” that blocked his PC after boot showing a scary screen 😉 I cleaned his PC with Kaspersky Rescue CD and it started working again.

    The only issue I experienced with Kav10 was a loss of all partitions on XP. I could recover them with testdisk, but I was a bit disappointed. It never gave me any problem on Win7, 8 and 8.1.

    Do you know if Kav10 is not still recommendable if you have XP? Do you know anything about these issues with wifi using some of these bootable AV?

    Thank you in advance,

    Bert
