One of the most common, and most difficult treats to eradicate, are the various fake antivirus “programs”.

If you get one of these and it is not stopped immedialtely by you or your real antivirus program, it may be necessary to consult a professional because this treat can deeply infect your computer in a short amount of time.

A good article about this threat can be found at the following link:

Opera?  No

Chrome? No

Firefox? No

Safari?  No

Internet Explorer 9?  Yes

As per the following source article, Internet Explorer is by far the best browser at keeping Malware off our computer. (But you do need to listen to it)

In this competition, IE9 was effective at preventing 92% of malware infections.  IE8 blocked 90%.

The nearest competitor only blocked 13%.

Note: SmartScreen Filter must be ON.

(this is about stock, off-the-shelf browsers, not security enhanced browsers such as Dragon, or add-ons and security and privacy plugins, etc.)

Investigators have found that it is likely that the fatal crash of Spanair Flight 5022 in 2008 was caused by a malware infection. It was determined that central computer system that monitors the aircraft systems for malfunctions was infected by a Trojan Horse. This infection evidently interfered with the ability of the computer system to flag an unsafe takeoff configuration, and the aircraft crashed seconds after becoming airborn.

The exact source of the infection has not been determined, but the investigation continues, and hopefully it will be pinpointed.   Investigators believe that the infection may have entered through a USB port or a VPN connection.

Aircraft rely more and more on computers and these critical systems need to be hardened against infection, and procedures need to be established and followed to insure that malware never has a chance to infect any such system.

FaceBook is very popular and there are about 400 million FaceBook users around the world.  Experts believe millions of users will fall for this attack and get infected.  Yes, that’s right – millions of FaceBook users will be infected by this targeted attack.

Unfortunately, 400 million users makes for a big opportunity for delivering malicious software.  Hence, Inboxes all over the world are being flooded with SPAM that is trying to induce FaceBook users to click on an attachment.  This attachment installs Trojans and other malware that is very dangerous to the computer user.   And unless their security software catches it, they will have no idea it is on their computer.

Our advice:

• Never clink on any link or open any attachment in any email that warns of dire consequences – be it about FaceBook or your bank, or anything else.
• Keep your anti-virus software up-to-date.
• Periodical scan your computer with a tool specially made for finding and eliminating malware.  One of the best is MalwareBytes Anti-Malware freeware version, which can be downloaded from http://www.malwarebytes.org/

Microsoft is working furiously to fix a deep vulnerability in Windows. This vulnerability has affected lots of third party software vendors, and has hit Adobe Reader particularly hard. 

This vulnerability is being very actively exploited in the wild, both through infected email and through infected web sites.  It is propagated via infected .pdf files.   Therefore it is very important to download and install the latest patch to Adobe reader.  We advise all readers to check to see if they have Reader version 8.1.1, and if they don’t, to install it immediately.

Also, look for a patch from Microsoft in the near future.    We predict Microsoft will issue a patch ASAP, and not wait for their normal second Tuesday update cycle because this vulnerability is so important to get plugged.

Computers that have been compromised and turned into remote control attack machines, otherwise known as Zombies, are becoming a significant problem.

These compromised computers are being used to attack a variety of Internet servers in a number of countries. These attacks can shut down web sites by overloading their servers with traffic.

For more information:

CypherTrust.com is a good source of information about Zombies and other security threats.

Your Mama always told you, “Don’t accept candy from strangers”.

Well, don’t accept e-cards from strangers, either.

And your Mama would tell you the same about e-cards, if she knew what was in them.

You see, they are likely to make your computer sick.

Sick as in virus infection. Way bad.

An new round of malicious e-greeting card spam is landing in in-boxes. It usually has the subject line “You’ve received a postcard from a family member!”

Whatever you do, do not open these spam emails, and do not click on the links.

If you do, you will be taken to a malicious web site that will attempt to install a variant of the Storm Trojan horse.

“Today’s greeting-card gambit tries a trio of exploits, moving on to the second if the machine is not vulnerable to the first, then on to the third if necessary. The first is an exploit against a QuickTime vulnerability; the second is an attack on the popular WinZip compression utility; and the third, dubbed “the Hail Mary” by the ISC, is an exploit for the WebViewFolderIcon vulnerability in Windows that Microsoft Corp. patched last October.”

This demonstrates the importance of updating all software to the latest versions. In this case, QuickTime WinZip and Windows are the targets. Users who have updated to the latest versions are protected.

And of course, it demonstrates the importance of being suspicious of all email that lands in your inbox.

One of the benefits of “virtual machine” software, such as Sandboxie and Greenborder and others, is that they purport to protect a Internet user form malware infection by containing the infection to the “virtual machine”.

We do recommend the use of such software, but users should be aware that virtual machine software is not invulnerable to exploitation, just as is any complex piece of software. Users should be careful to update these programs whenever updates are offered, as they may fix security vulnerabilities.

Google researchers have found malware lurking in 450,000 web sites, out of 4.5 million sites studied…. An amazingly large percentage.

Correction: Google researchers have clarified and revised their statements and it turns out that out of the Internet as a whole, they estimate less than 0.1% of web sites attempt to infect visitors with malware. Their original statements were speaking of a “subset” of risky sites that contained the much higher percentage of malware.

Many of the attacks focused on security defects in various programs that have Internet access. This is why updating those programs is critical to maintaining a secure computer or computer network.

Besides the obvious programs. such as Internet Browsers, don’t forget to update programs such as QuckTime, Flash, Real Media, Microsoft Office, Outlook Express, Adobe Reader and all your anti-virus and anti-spyware programs, etc.

Many users don’t even know they have QuckTime and Flash and many of these other programs on their computers.
