Kill Windows Viruses With An Ubuntu Live CD

ubuntu live cdToday’s anti-virus solutions are pretty reliable, protecting you from most of the common threats out there in the world. With safe browsing habits, there’s a rare chance that you’d ever get infected with malware. However, there’s never a guarantee that you’ll be completely safe if you are simply careful and run your anti-virus software.

Especially when it comes to zero-day threats, sometimes things just happen to you that you can’t blame on yourself. No matter if it’s your fault or not that your Windows system gets infected, you’ll need a plan to get rid of it before it renders your system completely unusable without serious recovery methods.

If the malware you’ve caught prevents you from touching any sort of tool that might have a chance in removing it, you should probably take a look at using an Ubuntu Live CD.

Anti-Virus on Linux?

While there are a handful of anti-virus solutions available for Linux, they aren’t made to combat Linux viruses. As there are barely any Linux viruses in existence (let alone in circulation), these tools still detect Windows viruses. Essentially, the only difference is that it runs in a Linux environment instead of a Windows environment.

How It Works

The great thing about an Ubuntu Live CD is that you can do anything you want on it, including installing programs, even though it’s just running temporarily in your RAM. Therefore, this means that you can run an Ubuntu Live CD, install an anti-virus solution, and then run a scan on your Windows files. It should then be able to detect and deal with any threats that it finds, without an infected Windows environment running in the background that could possibly block such measures from being taken.

Steps

As I summarized above, the process is quite simple. You’ll first need to download a copy of Ubuntu by going to their website. You’ll have the choice between downloading via your browser, or by using a torrent client. The torrent way is usually faster, but not all networks allow them to be used because many illegal software downloads occur using the protocol. However, it is completely fine for legal downloads such as Ubuntu.

You’ll then want to either burn it to a CD or write it onto a USB flash drive. To burn it to a CD, you’ll simply need to right-click on the .iso file that you downloaded, and choose the Windows Disc Image Burner application. It should then do the rest for you automatically. To write the ISO file onto a USB drive, you can use UNetbootin. If you would like, you may also follow Ubuntu’s easy instructions on their website for burning a DVD or writing to a USB drive, which I recommend at least taking a look at.

Next, boot up your system from the newly created media. You can accomplish this by entering your system’s BIOS by hitting buttons like F11, Escape, or Delete repeatedly – literally as soon as you turn on your computer. You’ll then want to head over to your boot tab and choose the DVD or USB drive as your primary boot device. Then hit F10 to save your settings and restart. If you wish, you may again follow Ubuntu’s instructions on how to do this.

Once loaded, you’ll want to head over to the Ubuntu Software Center and search for “clamtk“. When it appears, go ahead and install it. Clamtk is a graphical user interface for the Clam Antivirus software, the most popular open-source antivirus solution in existence.

Although Clamtk has a mechanism to update virus definitions, it only does so once a day, and cannot be initiated manually without going through a setup wizard. Either go through the wizard by going to Advanced –> Rerun antivirus setup wizard, then choosing Manual instead of Automatic. Then click on Help –> Check for Updates to install the latest definitions – if you’ve never used Ubuntu before, the menus are located in the top panel while the antivirus application is in focus, similar to a Mac. You may also avoid the wizard and simply open a terminal and run:

sudo freshclam

ubuntu live cd

Once the definitions are updated, head over to Scan –> Recursive Scan, and then choose your Windows partition. Wait a while for it to scan all your files and remove any threats, and you should be good to go! Just restart your computer with the Linux media removed, and you should be back in a virus-free Windows.

If you don’t want to use this particular antivirus for any reason, other popular choices include avast! and AVG. In fact, check out the anti-virus section on MakeUseOf’s Best Linux Software page for all recommended anti-virus programs.

Conclusion

Viruses and other malware can become quite a pest because of how difficult they are to remove. However, knowing some very useful tips like this one can help you save a lot of time and get on with using your computer. In case all techniques fail, you can always use the Ubuntu Live CD to back up your files before you restore your system. Also, there’s never a bad idea to taking a look at Linux to see if it could become your new main operating system!

Wireless Alphabet Soup Explained: What Is 4G, 3G, LTE, & More [MakeUseOf Explains]

We just absolutely love acronyms, don’t we? So much so that we use them literally everywhere to have a shorter way to name something. Whether it’s an official acronym such as USB or something unofficial like FB, there’s simply way too many for us to remember. Additionally, there are a good number of acronyms which have multiple meanings, all depending on the context you’re using them in.

When it comes to wireless service and our smartphones, there’s no shortage of acronyms – GPRS, EDGE, 3G, 4G, and LTE all exist to make our everyday lives even more confusing. If you are a tech-savvy reader you may know what they mean, but what about your mother? All of those acronyms tell you about the data speed and quality of connection, and to make things easier we’ll go in order from worst to best.

GPRS

The slowest of the slow is GPRS. Short for General Packet Radio Service, it was one of the first modern technologies for data transfers via cellular networks. It wasn’t the absolute first, as an alternate name for GPRS is 2.5G, or second and a half generation. Its speeds maxed out anywhere from 56–114 kbit/s. Don’t let that number fool you though, as any of today’s modern sites would take practically forever to load, even in their mobile versions.

While almost all areas within the United States which have cellular service use a better data service, there are still a few spots where only GPRS exists.

EDGE

The next technology is known as EDGE, or Enhanced Data rates for GSM Evolution. While officially more of a 2.9G, this standard is what people today commonly call 2G. The use of Internet over cellular networks really started to kick off under this technology, with rates of up to 1 Mbit/s but typically around 400 kbit/s. Compared to GPRS, this is a couple of times faster, and made Internet usage on mobile devices pretty bearable. However, as more people started to use the Internet through mobile devices, it spurred the development of even faster technologies.

3G

With the introduction of 3G, mobile Internet really kicked off. Third generation mobile communications brought major speed boosts, up to maximums of about 28 Mbit/s. This allowed smartphone apps to be downloaded at reasonable speeds, and made mobile Internet more accessible as a whole. Today, most areas in the United States which have cellular service are covered with 3G service, so anyone can access the Internet practically anywhere.

4G & LTE

Today, most urban areas are enjoying 4G service, or fourth generation. Again, there are more improvements to voice quality as well as data transmission speed, up to roughly 100 Mbit/s. Most of today’s smartphones are 4G-capable. Carriers often label it as “high speed data” and limit how much of it you can use before you’re forced to use a lower speed, usually 3G or EDGE. However, more recently there’s been a modification known as LTE, or Long Term Evolution. It is most commonly marketed as one unit – 4G LTE – but it simply improved on regular 4G by providing data transfer speeds of up to roughly 300 Mbit/s.

Your phone – whether Android or iPhone – still needs to be capable of LTE and not just 4G to be able to use “4G LTE”. 4G and/or LTE has also spawned the first few purely wireless Internet service providers. They’re just like your cable or DSL service providers, except wireless.

Conclusion

Thankfully, all of these technologies were created one after another, so we’re on a clear path of evolving our wireless communications to new levels. Currently it’s projected that 5G technology will become a standard around 2020, but who knows if there’s going to be another upgrade to 4G before then at the pace we’re currently going. One thing is for certain – everything is getting continually faster as our needs become more complex. Plus, it doesn’t hurt to be able to download Angry Birds in mere seconds.
