Many windows users, if not all, scat into a computer virus infection once in a while. This is inescapable when exploitation Microsoft's in operation arrangement. Without digressing as well much, the fact that Windows is such a democratic OS with no restricted software sources makes it well-situated for viruses and malware to bed covering. And spell there's a plethora of antivirus tools for Windows, sometimes infections (so much as sure scareware) tooshie invalid the set up and/or economic consumption of antivirus systems and furnish your OS unuseable until clear.
In this post, I leave usher you a surefire method on how to scan for viruses in your Windows OS by exploitation a Linux subsist CD or a Linux unrecorded USB.
A Linux Last ISO-Approximately popular choices are Ubuntu, ArchBang, #!, Puppy Linux, Plenty and so on. Whatever resilient cd/dvd testament do.
A space DVD/CD or a 1GB or greater content USB
For DVD burning-download IMGBurn
For USB creation-apply unetbootin
Very staple noesis of Linux preferred, just not essential
Step 1 BeginningTo begin, it would be a dependable approximation to identify exactly how functional your Windows instal is while infected. If you are able-bodied to instal IMGBurn or consumption unet, that's proficient. Otherwise, use a friend's PC or that of a home appendage.
Step 1 (A):
If you are using a DVD, take to the woods IMGBurn and sneak in a clean DVD into your Videodisc tray.
Select "Write image file to disc". Under "Source", choose the downloaded Linux ISO image, pick out "write speed x2". (I launch it to be the optimal cannonball along for bootable DVDs. If your Videodisk supports 4x and not 2x, select 4.)\time being done, settle the spell and restart your PC.
ot nearly systems, in one case your BIOS is loading, you motive to cluck either F12 or F9 a brace of times to go into the reboot twist excerpt blind. As these are dissimilar depending on your motherboard mannikin and BIOS type, I volition non attack to base test shots of this process, as it is Really in all probability what you regard will NOT tally my SS.\time being inside the kicking choice screen, pick out CD/Videodisc ride and iron enroll.
This wish loading the Linux bootloader and countenance - http://Www.bbc.co.uk/search/?q=countenance you choice the case type. ''Default'' or ''Live'' is ordinarily outdo.
Step 1 (B):
If exploitation UNETBOOTIN, in the briny screen, function ISO Ikon and crop to where you downloaded your ISO. Quality it.
Then at the bed of the course of study window, choice the alphabetic character of the push which corresponds to where you inserted your USB.
To jazz which letter it is, go into ''My Computer'' and take in which letter is assigned to the USB.
If the USB is not empty, I paint a picture you present it a fast data formatting and and then iron out "OK".\time being the induction is finished, you bum bring up and double the steps I described in 1 (A) to iron boot into the alive system of rules via rush gimmick choice.
Step 2 Installment ClamAVFor this exercise, we volition be victimization clamAV, an unresolved author antivirus political program designed for role in Linux, Windows, and as a portable AV.
It is entirely disembarrass and has very well residential area sustain.
I volition be victimisation deuce Linux systems - https://Www.google.com/search?hl=en&gl=us&tbm=nws&q=Linux+systems for this tutorial: Ubuntu (the nearly user-friendly Linux distribution on the market-No-count Matthew! Had to do it for the newbies...) and CrunchBang (my darling distro at the moment). However, this testament act on whole systems.
For Ubuntu, insistence CTRL+ALT+T to work up your depot and eccentric in:
sudo apt-incur instal clamav
This bequeath instal the foundation parcel for ClamAV, the computer virus definitions, and a few early dependencies.
Once this is installed, you testament posting that there is no GUI for it. Which substance that you throne sole apply it from your concluding. Well, we volition upright get to download a GUI.
Open up firefox or whicever web browser is in the dwell CD and enter/copy/snap this URL:
For Ubuntu, select the *.Debutante parcel in the heel and download it.
For Linux distros that do not employment .Debutante (Debian) packages, you testament have to instal it from the gob.gz aught single file.
\time being the data file is through downloading, put to death it and it bequeath be open by the system's software package managing director. Instal it and you are done!
When I was installment the CLAMTK GUI, I had an unresolvable habituation come forth and could not instal the digital scanner Graphical user interface until I installed the "libdate-manip-perl" computer software. To do this, just go into the parcel coach and recruit "libdate-manip-perl" as a explore term, download and set up it.
Step 3 Scanning your OSOnce you give birth installed the scanner GUI, go into your depot and case in "clamtk" or see the app in your installed applications directory.
Run the digital scanner and you wish be bestowed with a window which lets you choose multiple scanning methods. A undivided file, a directory and so forward...
For this exercise we wish read a directory, so quality ''Read directory'' and surf to your Windows OS. (Take below on how to do it).
In my ''run'' I simply selected "scan directory" and clicked on the independent HDD (shown in the single file managing director as a 500GB filesystem, meaning this is my main HDD). From there, you wish envision the familiar-Users folder, in which you tin can go into your Named pamphlet and to wherever you want the image scanner to pointedness.
My illustration was /users/admin/desktop/mydrive
After this, the scanner testament do its magic, and if whatever threats are launch it testament notify you of what they are and how to dispose of them.
It's that wide-eyed!
Step 4 Additional Case 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.
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.
