Getting Started with Windows 8: Automatic Maintenance

Wednesday, August 22, 2012

Windows 8 takes a bold leap in the automatic direction. Automatic Maintenance is hidden in the Maintenance section of Action Center but it does quite a bit: virus scans your computer, updates programs, runs disk maintenance and much more. Let’s get started!

Getting Started with Windows 8: Built-in Security

Saturday, August 18, 2012

Security has long been an issue with Windows. From the worms and Trojans and viruses that await an opening to your system to the paralyzing damage they can cause, Windows users, left with no other option, were forced to get antivirus software from paid and free sources. In Windows 8, Microsoft has updated Windows Defender to scan for viruses using an interface that much resembles Microsoft Security Essentials which proved to be a trust worthy option when it made its debut.  They have also included a Smart screen filter which will verify programs with a database before allowing them to run. In this video we will explore the new security features and see what Microsoft has to offer.  Let’s get started!

New Trojan "LuckyCat" Found in Microsoft Office for Mac

Tuesday, April 17, 2012

Mac users may think they're safe just because Mac is the Operating System of the Future. They are wrong. As Mac OS becomes more and more popular, so do the virus attacked.

Thanks to Securelist's Costin Raiu, a Kaspersky Lab expert, what has been found is a Mac-specific trojan called Backdoor.OSX.SabPub.a, also known as LuckyCat. The trojan is said to exploit a hole found in the Microsoft Office for Mac suite. As with most trojan attacks of this nature, it infects via vulnerabilities found in a Java exploit. Once infected, LuckyCat uses a vulnerability named CVE-2009-0563 to spread itself. This vulnerability is one found in Microsoft Office Documents. 

The purpose of the trojan at this point is unknown but Securelist had this to say:

We are pretty confident the operation of the bot was done manually -- which means a real attacker, who manually checks the infected machines and extracts data from them.
Securelist confirms that the trojan is currently active though at this point it is unclear what the intent of the attacker is.


How can I prevent myself from attaining these sort of viruses?


Turn off Safari's auto-open command
In Safari, go to the General section of the preferences and uncheck the option to "Open safe files after downloading." Safari may not open applications, but when checked it will open documents and media that may contain malicious executable code. It is recommended that this option is disabled/turned off.


Install an Antimalware/Antivirus Solution
Many Antivirus companies that provide solutions for PC also provide solutions for Mac. These solutions include NortonMcAfee and even AVG. It is always recommended that you have an Antivirus/Antimalware solution running at all times, not only for your safety, but also for the safety of others.

Never trust a program
If something asks you to install an item on your system, shut it down and confirm the source of the item. Only install programs on your system if you know exactly where they came from and what they do.

Apple releases security update for Flashback exploit

Sunday, April 15, 2012

Check if you've got the Flashback Trojan with this Handy Tool

Tuesday, April 10, 2012

It very rarely happens that the Mac Operating System is hit by viruses, if at all. The latest flavor seems to be something called the Flashback Trojan. What this Trojan does is modify the hosts file to redirect the Mac machine to fraudulent servers allowing the collection of sensitive information and data. According to Doctor Web there are around 550,000 Macs infected with the Flashback virus. Doctor Web later on tweeted a correction, saying that there are actually 600,000 Macs infected. Now, what can you do about it?


Thankfully, the Flashback Trojan, to our knowledge, does not cripple your system so it should be easy to remove the virus, even if you're not technologically inclined.


To check if you've got the Trojan, download the Flashback checker tool here. Unzip the file if necessary and run it.


Hopefully, if you don't have the virus you should see this:


Upon seeing this, it will be clear to you that you do not have the Flashback Trojan.


I ran the scan and it appears that I am infected. What do I do?


If your computer has been infected, you will need to open up Terminal. This can be found in the Utilities folder under Applications. You will need to manually remove the infection. You will need to carefully follow the instructions for removing the infection at F-Secure


How can I prevent myself from attaining viruses in the future?

Windows 8: A Drastic Improvement From Windows 7

Tuesday, September 20, 2011

Windows 8 is in its early stages and Microsoft officially let it free to the world outside of Redmond . I took the time to install it on my primary computer (usually a big no no for pre-beta builds of any operating system) and have noticed a big change in my computer’s performance – apart from the new User Interface.

Snow Leopard on Acer Aspire One: Part 7: Securing Your Mac

Saturday, July 30, 2011

Sophos 1If this site has championed one message when it came to Macs is that they are as vulnerable as Windows. Any Mac user who decides to continue unprotected risks harm to their system. We saw how easily mac Guard override Mac’s permissions system and tried to scam its victims out of money. If there is anything that we should do, is protect our Macs just like we would our Windows-based systems. Today, I will show you how.

Setting up the Firewall

All Windows systems come with the firewall automatically turned on. For some strange reason, Mac came with it turned off. Let’s change that.

  1. Go to your System Preferences.and select security.
    System Preferences 1
  2. Go to the Firewall tab, click the lock in the bottom left corner, insert your password and then turn on the fire wall.
    System Preferences 2

Prompting for a Password at Logon

Want to prevent unwanted users from being able to get into your account? All you need to do is turn off auto login. Here is how you do it.

  1. Go back to the System Preferences Main page and click Accounts.
    System Preferences 1
  2. Again, you will need to unlock the setting to make changes. Then you go to automatic log in and choose off. The next time you boot up, you will need to enter the password that you made in set up.

Installing an Antivirus

Regardless of your operating system, you should always install an antivirus. After its incredible handling with Mac Guard, I have decided to entrust Sophos with the security of my Mac. Here is how you install it.

  1. Download Sophos Home Edition for Mac
  2. Open the installer
  3. Double click on the package
    Sophos 1
  4. Continue like a normal installation
    Sophos 2
    Sophos 3
    sophos 4
  5. At the end, you will see a shield in the menu bar – which is where you access Sophos and the installer will give you some general information.
    Screen shot 2011-07-30 at 7.16.15 PM
  6. Like with all successful installations, you will see this screen.
    sophos last
  7. Eject the Sophos DMG image. You will also notice that you can scan files by right clicking on them.
    Screen shot 2011-07-30 at 7.23.13 PM

These three things will make your system safer and more secure from cyber attacks. however, the best antivirus isn’t ‘idiot-proof’ so browse the web with care and avoid site that you suspect may be crawling with viruses. Otherwise, you are only asking for trouble.

Apple Makes Macs Easy to Hack Out of the Box–or on the outside of the box

Tuesday, July 26, 2011

You would be amazed at how shipping some simple information inside a box rather than outside would curb massive security threats that now encompass Apple’s new Macs. If the operating system itself didn’t get enough of a beating by malware, hackers can infiltrate your Mac with information that is displayed on stickers on the outside of the box.

Tips and Tricks: Speeding Up Windows 7

imageWhen you first install Windows 7, the first thing you notice is that it is very snappy and everything runs smoothly. With time, however, simple tasks such as starting up and shutting down become tedious chores as you wait longer to get to the tasks that you need to do. In this article, I will discuss some of the tactics that I used to speed up my lagging system – and might I say, it now feels like I installed Windows 7 yesterday.

Hotmail allows you to Spot Compromised Friends

So you receive a spam message or fraudulent email from a friend of yours. Chances are it wasn’t your friend who sent it. Hotmail will now allow you to report instances where your friends' account may have been hacked.

“When you report that your friend’s account has been compromised, Hotmail takes that report and combines it with the other information from the compromise detection engine to determine if the account in question has in fact been hijacked. It turns out that the report that comes from you can be one of the strongest “signals” to the detection engine, since you may be the first to notice the compromise,” says to Microsoft’s Dick Craddock.

Two things will immediately happen once you click on My friend’s been hacked in the Mark as menu:

  1. The account can no longer be used by the spammer
  2. Your friend will be put through account recovery to allow him/her to take back control of the account.

Another measure that Microsoft will take to fend off hijackers is to prevent customers from using common passwords when they create new Hotmail accounts.

Mac OS X Update Fails to Protect its Users

Thursday, June 2, 2011

Mac users once felt protected on their nearly perfect Macs. Mac Defender has proven that the simplest of viruses that has been experienced in the Windows world can get into a Mac and wreak havoc very easily. Apple released an update to remove the malware. Not only does it protect you from a limited amount of malware, it allows you to run it. Apple’s security measures in general have been subpar. If the same virus been on a USB stick, it wouldn’t have been detected.

New Version of Mac Rogue Bypasses Security Check

Tuesday, May 31, 2011

This screenshot shows the interface of the latest Mac rogue antivirus malware dubbed MacGuard. In a previous article, the rogue that has been taking Mac users by storm was exposed and dealt with. However, Windows users are used to these and are better equipped and like on Windows, these finely built viruses know how to get through security. That virus can be stopped by simply not installing it, or simply not entering your user password. Well, it turns out that a new version of the virus can bypass the Mac password and simply doesn’t need it. As was explained in the previous article, a Mac virus isn’t a trip to the Trash. Therefore, an antivirus is a necessity and that may be the first thing that Mac users should look into – and fast.

Macs Struck with Malware

Friday, May 27, 2011

One of the first reasons Mac users would use to claim their superiority over Windows was malware protection – or the lack of its need. But Mac users are now facing a startling reality, Macs aren’t as safe as they bloated. Security experts are warning Mac users to be vigilant and download antivirus software as the operating system comes under attack. The latest threat in the Mac world is a recent “Mac Defender” program, a Trojan that also goes by the names “Mac Security” and “Mac Protector.”
