ALERT! New scareware scheme

This news just in from AV solution provider Sunbelt Software:

Security researchers have uncovered a new scareware attack named MSIL/Zeven, which lures users into downloading a fake antivirus software.

The malware identifies users' browsers and displays an authentic-looking version of the browsers' malware warning page, as a way of convincing individuals that the alert is real. When users click on the link presented in the fake warning page, they are directed to a website where they can purchase antivirus software known at "Win7 AV."

The site that offers the antivirus software is designed to look identical to a legitimate Microsoft website, though security experts warn users that the page is fake. To defend against these malicious crimes, leaders in the field advise users to be skeptical of what they download from off the internet, as well as install the latest malware protections.

Many researchers have found the new attack website's design is so close to the real thing, even skilled professionals have a difficult time deducing whether it's a fake.

Recently, security analysts uncovered scareware malware loaded onto a computer at a major airport in England. The presence of malware on public terminals could be a dangerous signal for web users, who may be giving their private information to cyber crooks without even realizing it.

Today's Tip: Danger, false security ahead

OSX Logo"Bad data is worse than no data as it induces one to proceed in the wrong direction with a false sense of confidence." Unknown

The last few days I have been involved in some spirited debate with regard to the new iPad. People who have them are generally "in love" with the device. People who write techonolgy reviews for a living, not so much. The inability to multi-task, absence of support for Flash (sorry, no Farmville on your iPad), no USB port or camera for video conference are the common complaints that render the iPad little more than a beautiful and expensive gizmo to show off and establish your status as someone "cool".

Of course this has once again stirred the MAC vs. PC debate. The battle cry of MacNoids everywhere (other than "it's so easy to use") is "I love my Mac because I don't have to worry about Viruses and spyware like on a PC".

I was browsing Facebook today when I came across the gem at the top of this post. There is an antecedent to that maxim, penned by Arthur Conan Doyle, and placed on the lips of Sherlock Holmes: "It is a capital offense to form theories before one has data. Insensibly, one begins to twist facts to suit theories instead of theories to suit facts." Now I'm not here to suggest you should NOT own a MAC, nor am I suggesting one platform is superior to the other (MAC vs PC). What anyone contemplating the purchase of an Apple product NEEDS to know is the data you may have read or heard that "MAC is more secure than PC" is BAD data and you would do well to proceed with caution on BOTH platforms. As the MAC footprint grows, so too do the threats and malware targeting OSX.

Windows 7I repaired two PC's in the past week that were poorly maintained and severely compromised with rogue security software. Some might say this is proof the PC is less secure. That's called "twisting the facts to suit the theory". In each case the problem was not the PC (the hardware), it was not the operating system. The problem was a combination of exposing the system to known dangerous parts of the Internet (P2P networks and torrents) while failing to run regularly updated security software from a reputable provider, failure to properly update the operating system against known vulnerabilities, and failure to recognize social engineering at it's finest (fake security pop ups previously discussed on this site). Of course all three contributing factors are the responsibility of the User or Owner of the computer, but taking personal responsibility is not popular or in fashion with so many people. Easier to blame it on that pesky Bill Gates! If not for the failures noted, there would have been no repairs necessary. Penguin

As I have stated before, anyone who will fall for a phishing scheme, or who can be tricked into installing rogue security software, can be tricked regardless of their preferred computing platform. New vulnerabilites in OSX, Windows, and Linux are discovered every day.

The moral of the story? Don't proceed towards Macintosh with a false sense of security based on the "data" you've read or heard... proceed with an abundance of caution every single time you sit down to see what your Facebook and Myspace friends are up to, irrespective of your preferred computing platform! YOU are resonsible for the health and protection of your computer, not Steve Jobs, not Steve Ballmer, not Linus Torvalds.

This is a test!

Can you spot the warning signs in the screen capture below?

It's a sneaky malware attack designed to sucker you into installing "security" software designed to extort money from you (much like other products I've talked about previously).

The threat discovered by Sunbelt Security is very real and very tricky since most casual PC users may have never encountered a BSOD. Read about what Sunbelt says about the threat here

Fake BSOD

Your first clue should be that a Windows "STOP" error, also known as a BSOD (Blue Screen of Death) does NOT happen inside a web browser window.

Your second clue should be that in the event of a real STOP error, there is never an option to repair anything.

Remember, it's a nasty jungle online. Surf safe and smart.

Today's Tip: Virtual Memory, do you have enough?

Physical RAMSo you've just added additional memory to your computer because a friend told you it would help speed things up, but you haven't seen any improvement whatsoever. This could be because even though you've added more physical RAM to the computer, you haven't adjusted your operating system's virtual memory settings. Virtual Memory settings are usually created automatically at the time your Operating System is installed on your computer, so if you've upgraded with more physical RAM, you need to adjust the virtual memory settings accordingly. So how much virtual memory should you have? General rule of thumb is 1.5 times the value of physical RAM in the computer. This means if your computer has 2 GB Physical RAM (2048MB), your virtual memory (also known as a pagefile) should be 3 GB or 3072MB. Set this value by right clicking on "My Computer" Select the "properties" option and from there, the "Advanced" tab. Click "Settings" in the Performance section, and when the resulting dialog box appears, select the "Advanced" tab once again. Here you will see "Virtual Memory" in the bottom half of the window with the option to "Change". Follow the prompts to set your pagefile or virtual memory to the approriate value. I've provided a couple of screen captures below to point you in the right direction. If you're still uncertain, send me email and I'll be happy to guide you through!
