Many Windows users, if non all, extend into a virus infection in one case in a piece. This is inescapable when using Microsoft's operational scheme. Without digressing overly much, the fact that Windows is such a pop OS with no restricted software system sources makes it gentle for viruses and malware to paste. And while there's a embarrassment of antivirus tools for Windows, sometimes infections (so much as sure scareware) rear end disable the instal and/or purpose of antivirus systems and give your OS unserviceable until vindicated.
In this post, I bequeath present you a surefire method on how to run down for viruses in your Windows OS by exploitation a Linux hot CD or a Linux inhabit USB.
A Linux Exist ISO-Around popular choices are Ubuntu, ArchBang, #!, Pup Linux, Whole lot and so on. Whatever last cd/videodisk volition do.
A blank DVD/CD or a 1GB or greater capacitance USB
For DVD burning-download IMGBurn
For USB creation-practice unetbootin
Very BASIC knowledge of Linux preferred, but non essential
Step 1 BeginningTo begin, it would be a ripe melodic theme to name equitable how usable your Windows set up is spell infected. If you are capable to instal IMGBurn or economic consumption unet, that's near. Otherwise, use of goods and services a friend's PC or that of a kin extremity.
Step 1 (A):
If you are exploitation a DVD, be given IMGBurn and stick in a blank Videodisc into your DVD tray.
Select "Write image file to disc". Nether "Source", select the downloaded Linux ISO image, select "write speed x2". (I institute it to be the optimal bucket along for bootable DVDs. If your Videodisc supports 4x and non 2x, select 4.)\time being done, finalize the write and resume your PC.
ot to the highest degree systems, erstwhile your BIOS is loading, you take to pawl either F12 or F9 a mates of multiplication to go into the thrill gimmick pick sieve. As these are dissimilar depending on your motherboard mannikin and BIOS type, I testament non seek to Post blind shots of this process, as it is Identical expected what you picture leave NOT equal my SS.\time being inside the kicking survival screen, prefer CD/Videodisk parkway and fourth estate figure.
This will charge the Linux bootloader and lease you choice the example typecast. ''Default'' or ''Live'' is commonly best.
Step 1 (B):
If victimisation UNETBOOTIN, in the briny screen, manipulation ISO Simulacrum and browse to where you downloaded your ISO. Select it.
Then at the backside of the computer program window, prime the varsity letter of the aim which corresponds to where you inserted your USB.
To have a go at it which missive it is, go into ''My Computer'' and undergo which letter of the alphabet is assigned to the USB.
If the USB is not empty, I propose you hand it a quick initialise and and then fight "OK".\time being the facility is finished, you lav bring up and iterate the stairs I described in 1 (A) to boot into the know scheme via flush device natural selection.
Step 2 Installation ClamAVFor this exercise, we testament be victimisation clamAV, an undefendable source antivirus program intentional for apply in Linux, Windows, and as a portable AV.
It is altogether discharge and has identical respectable biotic community funding.
I will be using two Linux systems for this tutorial: Ubuntu (the near user-friendly Linux statistical distribution on the market-Regretful Matthew - http://search.huffingtonpost.com/search?q=Matthew&s_it=header_form_v1 ! Had to do it for the newbies...) and CrunchBang (my favourite distro at the moment). However, this bequeath crop on altogether systems.
For Ubuntu, pressure CTRL+ALT+T to contribute up your endmost and typewrite in:
sudo apt-convey establish clamav
This will set up the baseborn software package for ClamAV, the computer virus definitions, and a few early dependencies.
\time being this is installed, you will point out that thither is no GUI for it. Which substance that you stool only if use it from your terminus. Well, we leave scarcely take to download a GUI.
Open up firefox or whicever web browser is in the last CD and enter/copy/snap this URL:
For Ubuntu, choose the *.Debutante software program in the name and download it.
For Linux distros that do not use of goods and services .Debutante (Debian) packages, you volition induce to set up it from the Jack.gz zipper filing cabinet.
\time being the Indian file is through downloading, carry through it and it testament be open by the system's parcel coach. Set up it and you are through with!
When I was installing the CLAMTK GUI, I had an unsoluble dependence egress and could not instal the electronic scanner GUI until I installed the "libdate-manip-perl" packet. To do this, scarce go into the software system handler and go in "libdate-manip-perl" as a lookup term, download and install it.
Step 3 Scanning your OSOnce you suffer installed the image scanner GUI, go into your terminus and typewrite in "clamtk" or see the app in your installed applications directory.
Run the electronic scanner and you bequeath be conferred with a windowpane which lets you pick out multiple scanning methods. A single file, a directory and so forward...
For this representative we volition run down a directory, so take ''Read directory'' and browsing to your Windows OS. (Interpret infra on how to do it).
In my ''run'' I barely selected "scan directory" and clicked on the independent HDD (shown in the filing cabinet manager as a 500GB filesystem, meaning this is my principal HDD). From there, you bequeath witness the familiar-Users folder, in which you hindquarters go into your Called leaflet and to wherever you demand the scanner to point in time.
My instance was /users/admin/desktop/mydrive
After this, the scanner volition do its magic, and if whatever threats are found it leave apprise you of what they are and how to toss out of them.
It's that uncomplicated!
Step 4 Extra Example on Crunchbang (#!)Disclaimer: Free pardon the ''Pedobear" terminal ASCII. I found it hilarious so I kept it.
Installing clamAV (same syntax - sudo apt-get install clamav):
Downloading ClamTK from sourceforge:
Installing the DEB package:
Running ClamTK (just run the terminal and enter ''clamtk''):
And that's it.
Final Notes:I hope the above article was useful and helped you weed out a nasty infection or two. This is a great method of utilising a scanner without having to actually go into the system itself and clean it that way. It is a good method for a couple of reasons: for one, you will not be held back by any detrimental effects caused by the infection; number two, it's advantageous to using safe mode as some AV scanners do not work very well in Windows safe mode. Some of their drivers do not get loaded properly or at all. Scanning the main OS as if it were a external HDD eliminates these problems.
A few pointers in staying safe on Windows:
Install a good antivirus system and/or firewall. A good Firewall and AV combo is COMODO, but it's quite needy in terms of instructing your environment and the programs you consider safe. As the engine behind comodo has execution prevention, sandboxing, and many other advanced features, it is not suited for newbie users. Give their free internet security suite a spin to see if you like it. Other AV systems that come highly recommended are NOD32, Kaspersky, Avast!.
Be wary of programs that you download, and scan all downloads before opening/executing.
Only download installers/exe's from trusted sources or at least ones that come recommended.
Do not open email attachments that contain the file extension ".exe".
Use common sense-if you do not know what an executable (.exe) does, do NOT run it.
If you are unsure, google the file in question and see if other users have come across the file and check up on their experiences. This goes for viruses as well. If you have an infection, google it to find info on it, you are likely to stumble upon a solution.
And lastly, if you somehow managed to catch something so horrible no method of removal works, reinstall your Windows and be more careful next time.

Hope this guide helps you.
