Hello, I have decided to open a topic about the following subject:

Which is the safest way to scan your PC and detect and remove various malware from it?

My solution is booting a live OS from a CD or USB drive to scan your Hard-drive remotely, safely and fully with an advanced anti-malware software from distance. The idea for this topic came because I have seen far too many viruses that block out anti-malware programs and change different boot settings of the PC.

I have prepared a tutorial on how to install a live OS here:

Step 1: Download a live Windows OS image.
There are many live images out there that may serve you. Linux distributions are most notorious due to their fast booting and effectiveness. However, most users may not have sufficient experience to use Linix distros and look for live Windows versions. You should be advised that the best way to having a live Windows OS is to make one yourself. In order to make a live Windows image, check this tutorial:

Step 2: Downloading Rufus.
While you download the OS, download a bootable drive making program, called Rufus. It is recommended that you have a USB Flash drive with memory abouve 4 GB for this. Download Rufus from their official website:

PS: For creating a bootable drive, you can also use other programs such as Windows USB/DVD Download Tool. You can download it from here:

Step 3: Open the downloaded .Zip file and extract the file, called 'Windows 7 live cd from usb' in a folder you know. I extracted it in Documents.

Step 4: Follow the instructions in the image below in order to mount the image and install it onto your removal disk drive(Flash Drive, external Disk Drive, State Drive or any other memory carrier).


Step 5: When you are done, configure your BIOS menu to boot from USB drives as a priority. To do this:
1-Restart your computer and as soon as the screen blacks out try tapping one of the following keys (For different manufacturers they vary):
-F1, F2, or F3 function keys
-ESC key.
-Delete or Del keys.

Step 6: Once you have booted into your live CD, connect to the internet if not connected (You should be, unless it is a Wi Fi connection) and then download and scan your computer with an anti-malware tool using the tutorials for installing them from here:

I would use Linux and ClamAV to scan a PC if I musn't reinstall it, what is your take on this? Do you think that it is a necessary thing to do or do you have a better way to do this?
