Trojan preying on out-of-date Java installations
Aug 22nd
Sunbelt Blog | August 20, 2010
A piece by Marian Radu on Microsoft’s Technet Blog is warning that users who have failed to update the Java Runtime Environment (JRE) on their machines are vulnerable to drive-by downloads by a Trojan called Unruy. That Trojan has been associated with rogue security products. Radu said the vulnerability (which was patched in March) is being actively exploited.
Browsers running JRE versions up to version 6 update 18 are vulnerable. The current JRE version today is version 6, update 21.
Users can easily check their version of Java and download necessary updates here: »www.java.com/en/download/manual.jsp

How to prevent “Scareware” (Rogue Antivirus)
Jan 19th
Practically all my service calls the last two months have been due to Scareware related issues. Rogue anti-virus programs that claim every program is infected and that for some amount of money your computer can be secured. Unfortunately, the scareware program IS the infection and your money is sent immediately to some far off country while little if any relief is provided for your payment. It is a scam. And the worst part of it is you no longer have to be surfing the seedier side of the Internet to become a victim!
The authors are actually paying people to infect you, which means it is being included in blogs, forums, even websites you actually pay to use. Typically they rely on your trust of a website to open up the security of your web-browser, to drop your guard, to OK a download.
They operate primarily by using Javascript Code. Javascript is very common and the internet would be a horribly bland place without it, which makes it the perfect vehicle. Javascript are little snippets of code that are included in websites to generate dynamic content, like time stamps and the like. They allow a website to offload some of the heavy lifting and More >

Using LIMEWIRE safely
Jul 29th
A majority of my service calls have two things in common. A Virus and Limewire. Limewire is a very popular P2P program typically used for sharing music and videos over the internet. Unfortunately, it is unmoderated and many files are mislabeled to get you to download them, where they then reveal their true nature, loading spyware/malware and viri onto unsuspecting users. In the good old days of viri, they simply trashed your operating system, forcing you to reload everything. These days they try to remain undetected, lurking in the background, sending your passwords and other information to some secret server deep in Siberia, or popping up porno ads when Grandma looks up “Whitehouse” on the internet.
Safely using LimewareWhile the legality of P2P programs is still being fought over in the courts and Internet Service providers are still struggling under the increased bandwidth useage, Limewire is going to be around, if only because it’s what all the kids like to use. So, with a few tips outlined below, let’s try to at least make it safer to use!
1) Secure your operating system! Securing Windows XP will assist you in securing your Windows XP installation. Windows Vista users should be ok out of the More >
