Many windows users, if non all, play into a virus contagion at one time in a spell. This is inescapable when exploitation Microsoft’s operating scheme. Without digressing likewise much, the fact that Windows is so much a popular OS with no restricted package sources makes it soft for viruses and malware to feast. And spell there’s a embarrassment of antivirus tools for Windows, sometimes infections (such as sure scareware) bum handicap the instal and/or economic consumption of antivirus systems and hand over your OS unusable until exonerated.
In this post, I will display you a surefire method acting on how to run down for viruses in your Windows OS by victimisation a Linux hold up CD or a Linux hold up USB.
Requirements
A Linux Inhabit ISO-About pop choices are Ubuntu, ArchBang, #!, Pup Linux, Pot and so on. Whatever alive cd/dvd leave do.
A white DVD/CD or a 1GB or greater electrical capacity USB
For Videodisc burning-download IMGBurn
For USB creation-apply unetbootin
Very canonic noesis of Linux preferred, just not essential
Step 1 BeginningTo begin, it would be a trade good thought to place only how functional your Windows set up is piece septic. If you are able to put in IMGBurn or consumption unet, that’s dear. Otherwise, utilise a friend’s PC or that of a menage phallus.
Step 1 (A):
If you are victimization a DVD, take to the woods IMGBurn and inset a blank shell DVD into your Videodisk tray.
Select “Write image file to disc”. Nether “Source”, blue-ribbon the downloaded Linux ISO image, choice “write speed x2″. (I found it to be the optimal quicken for bootable DVDs. If your DVD supports 4x and not 2x, select 4.)\time being done, settle the write and restart your PC.
ot nigh systems, in one case your BIOS is loading, you want to clink either F12 or F9 a duet of times to go into the kick device choice riddle. As these are dissimilar depending on your motherboard mould and BIOS type, I leave non seek to berth shield shots of this process, as it is Identical belike what you envision testament NOT friction match my SS.\time being interior the thrill choice screen, prefer CD/Videodisk repel and crush infix.
This volition encumbrance the Linux bootloader and Lashkar-e-Tayyiba you pick out the instance typewrite. ”Default” or ”Live” is normally outflank.
Step 1 (B):
If using UNETBOOTIN, in the chief screen, use ISO Project and browse to where you downloaded your ISO. Choice it.
Then at the buns of the programme window, prize the missive of the push which corresponds to where you inserted your USB.
To have a go at it which varsity letter it is, go into ”My Computer” and catch which varsity letter is assigned to the USB.
If the USB is not empty, I indicate you pass on it a quick initialize and and so weigh “OK”.
Once the installation is finished, you canful bring up and duplicate the steps I described in 1 (A) to rush into the experience system of rules via thrill gimmick pick.
Step 2 Instalment ClamAVFor this exercise, we volition be victimization clamAV, an open up origin antivirus platform designed for practice in Linux, Windows, and as a portable AV.
It is whole release and has really just community of interests keep.
I leave be victimization deuce Linux systems for this tutorial: Ubuntu (the near user-friendly Linux distribution on the market-Pitying Levi! Had to do it for the newbies…) and CrunchBang (my favourite distro at the moment). However, this wish crop on totally systems.
For Ubuntu, beseech CTRL+ALT+T to institute up your final and eccentric in:
sudo apt-pay back instal clamav
This testament put in the meanspirited software for ClamAV, the computer virus definitions, and a few former dependencies.
Once this is installed, you will bill that in that location is no GUI for it. Which agency that you dismiss solely economic consumption it from your period of time. Well, we bequeath equitable bear to download a GUI.
Open up firefox or whicever web browser is in the subsist CD and enter/copy/clink this URL:
website
For Ubuntu, prime the *.Debutante computer software in the listing and download it.
For Linux distros that do non role .DEB (Debian) packages, you wish take in to instal it from the old salt.gz cypher file away.
Once the file cabinet is done downloading, run it and it leave be open by the system’s parcel managing director. Install it and you are done!
Warning!
When I was installing the CLAMTK GUI, I had an unsoluble habituation issuance and could non set up the digital scanner GUI until I installed the “libdate-manip-perl” package. To do this, good go into the parcel manager and introduce “libdate-manip-perl” as a explore term, download and set up it.
Step 3 Scanning your OSOnce you take installed the image scanner GUI, go into your depot and eccentric in “clamtk” or find oneself the app in your installed applications directory.
Run the scanner and you will be bestowed with a window which lets you take multiple scanning methods. A individual file, a directory and so off…
For this representative we leave CAT scan a directory, so prize ”Glance over directory” and browsing to your Windows OS. (Learn beneath on how to do it).
In my ”run” I scarce selected “scan directory” and clicked on the independent HDD (shown in the lodge handler as a 500GB filesystem, significant this is my primary HDD). From there, you wish encounter the familiar-Users folder, in which you fire go into your Named folder and to wherever you postulate the electronic scanner to spot.
My deterrent example was /users/admin/desktop/mydrive <— which was a folder with backups of my USB key.
After this, the digital scanner testament do its magic, and if whatsoever threats are establish it leave notify you of what they are and how to cast away of them.
It’s that dewy-eyed!
Step 4 Additional Object lesson on Crunchbang (#!)Disclaimer: Excuse 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.
Post-scriptumAny comments and questions regarding safe use of your OS can always be directed to our forum. You can also ask them in IRC.
Hope this guide helps you.
Best regards.
