One thing I like about Linux is its versatility. It has no hardware restriction, unlike other operating systems. So versatile, in fact, that you can even install the whole system on a bootable USB flash drive.
One advantage of having a bootable Linux anti-virus rescue USB is that you can scan a malware-infested drive without booting into your native operating system. You can just boot from the flashdrive and scan the drive from there.
Step 1. Create the Ubuntu Live USB.
[*Download Ubuntu ISO from here *](http://www.ubuntu.com/)

Step 2. Boot from your Ubuntu Live USB.
Step 3. Open Mozilla Firefox and download Avira AntiVir Personal – FREE Antivirus for Linux.
[*Download Avira binary*](http://dlpe.antivir.com/package/wks_avira/unix/en/pers/antivir_workstation-pers.tar.gz)
[*Download License file for Avira*](http://dlce.antivir.com/down/windows/hbedv.key)
Step**4. If the downloaded Avira tar file location is not in your /home/ubuntu (~/) folder, copy or move the file (together with the license file – hbedv.key) into that folder (for easier installation).
Step 5. Extract the tar file by double-clicking (GUI) or using the terminal.
Step 9. Start avguard (*“sudo avguard start”*), then update the virus database (may take a while). *“sudo /usr/lib/AntiVir/guard/avupdate –product=Guard*”
Step 10. Mount the drives you want to scan and run Avira with the following options. *“sudo avscan –scan-mode=all -e -del /media”. *This will scan all files, try to repair the infected ones, and delete the ones it could not repair. Read the manual for more info (/home/ubuntu/antivir-workstation-pers-3.1.3.4-1/doc).
Other advantages of using the Live USB:
**- Recover or access data from a drive with corrupted operating system.
– Recover a damaged partition table.
– Resize or repartition a drive.
– Boot onto other computers that may be unsecure, unsafe, or may have virus/malware.
– Avoid keyloggers or other programs designed to steal information when logging into your important accounts such as a bank account.
– Diagnose various computer problems such as hardware and software issues.
– many more.
