You Are Your Computer Security!

It has been a long time now since I wrote an article. In this blog post, I will explain (and teach as well) how and why people need to be aware of the Malware spreading in the wild and how you are your own computer security.

Sounds interesting? Well, then read on.

Let me tell you on how things are arranged on my system for giving me the maximum protection against Malware. It has now been close to an year since I decided to change from a licensed antivirus solution and switch to Windows Defender to see if malware is able to infect my system. Wait. Did I hear “Are you crazy? You are just too dumb!”?

[![Antivirus](http://i2.wp.com/omgdebuggingblog.cloudapp.net/wp-content/uploads/2015/02/55466648.jpg?resize=250%2C250)](http://i2.wp.com/omgdebuggingblog.cloudapp.net/wp-content/uploads/2015/02/55466648.jpg)Well that’s funny!
Don’t worry people. I have turned on my Windows Defender (I don’t think that it is a better idea to run simply Windows Defender in a Corporate Environment though!) and do a monthly scan with [](https://www.malwarebytes.org/ "MalwareBytes") and [](http://www.gmer.net/ "GMER"). Yup. That’s it. For security purposes, I have turned on Windows Defender alongside the Windows Firewall. Now, keeping the software aside, the best defence is having common sense and asking questions to yourself. Let me tell you an incident which happened a few days ago. I get a message on Steam Chat from a friend claiming that the below picture is extremely funny. Since it was from one of my trusted friends, I decided to open the link which was basically a shortened link (bit.ly). On clicking on the link, Internet Explorer opened and it asked me to download and save a file. I saw that the extension was “.scr” which is the Windows Screensaver file. I asked myself as to why an image has got a Screensaver Extension and so I decided not to download the file. Turns out after a few days, I see that this is malware spreading through Steam Chat. You can read more over here – [https://blog.malwarebytes.org/online-security/2014/09/steam-threats-what-they-are-and-what-you-can-do-to-protect-your-account/](https://blog.malwarebytes.org/online-security/2014/09/steam-threats-what-they-are-and-what-you-can-do-to-protect-your-account/ ) So, here are the best tips I could think of which could teach you self defense – ### 1. Start asking yourself the question before doing anything on the computer. Even though computers have simplified each and every task by heaps. This has got both it’s positive and negative effects. You obviously know the positive aspect of this so let me tell you about the negative aspect. For example let us consider the way we install something from an Installer Package. Admit it. Most of us would simply click on Next -> Next -> I Accept -> Next -> Finish. Did you ever spend some time before checking and asking yourself what the program actually installs? (If you really don’t have time, you might find [Unchecky](http://unchecky.com/ "Unchecky") very useful). ### 2. Disable that nasty Autorun. Windows makes it very convenient for you in the sense that it could automatically launch applications when a disk (CD, DVD, Hard Disk etc) are attached to the system and launch the appropriate program. Malware can easily modify the autorun entries and whenever you attach something to the system, the malware would run and bingo, you have got yourself an infected system! If you don’t know how to disable the Autorun, follow this link – [http://www.redmondpie.com/how-to-disable-autorun-autoplay-in-windows-7-and-windows-8/](http://www.redmondpie.com/how-to-disable-autorun-autoplay-in-windows-7-and-windows-8/) ### 3. Have the habit of scanning external drives whenever they are plugged in. That sounds time consuming right? But, trust me. It is worth the effort. Since you have already disabled the nasty autorun, the malware inside the attached drive won’t run until you explicitly ask it to run. ### 4. Don’t trust/start downloading anything from the Search Results you get. The heading might not help you understand what I really mean. Suppose I want to download the drivers for my laptop and I do a simple search on Google as below. Can you guess which one is the valid and trusted link?

If you said that it is the 3rd link, then that’s correct. If you did not get the answer then try asking yourself (Like I said in the first point) – Why is a 3rd party providing links to the drivers? What do they gain? What if something goes awry, who will take the responsibility then? I hope you got the point. Once you start looking carefully through the search results, you would automatically tend to skip the useless links which would also save your time and a lot of headache. ### 5. Don’t download illegally and from 3rd parties.

This is said by all of the Security people around the globe but well who listens? In today’s world, obfuscating any file on the system is simple and very hard to crack. For example, I download the trial version of a legal application, embed it with another malicious executable and then repack it to give the executable the exact look of the legit application. Now, whenever one runs this application, the malware is executed and copied to the appropriate directories and simultaneously, the legit application is launched. This way, even if an Antivirus detects that there is another file which is malicious, the user thinks that it is a false positive and asks the Antivirus to shut up. So, now who is at fault?

6. Keep the software updated.

It has been said again and again to keep the software on the system updated. It turns out that most of the people don’t do this. According to today’s malware makers don’t try much on exploiting the Operating System but rather the applications which are installed on the system. New versions of the software are released frequently so make sure that you update them. You could also have a day once every two weeks where you update everything on the system.

I hope this post made you aware at least a bit on how you could protect your system with minimal software.
