This is one of the safest tools available to eliminate virulent files from your system forever. As soon as you insert a pendisk in your system, this tool immunizes it to prevent the transmission of any harmful file. Further, this application creates a special folder by the name, autorun.inf. This folder bears unique protection permissions that save your pendisk from future attacks when plugged into virus infected computers.
Ninja Pendisk is absolutely easy to use. It is available for free of cost and does not require any configuration or installation at all. When you activate the program, it settles on the system tray. It does not interfere with the normal functioning of your installed programs. It only gets activated when you insert a pendisk in your system. It scans the USB device for its malicious or harmful content. As soon as it detects an infected or harmful file, it permanently deletes it from the device.
If you use USB devices frequently, then you can add this program to your Startup Menu in Windows. Once you launch this program, you will see an option, “Add Windows to startup”. You just have to click on the option to make this program accessible from your starting menu.Download

MS08-67 resolves a vulnerability in the server Relevant Products/Services service that affects all currently supported versions of Windows. Because the vulnerability is potentially wormable on older versions of Windows, Microsoft is encouraging customers to test and deploy the update as soon as possible.
Microsoft discovered the vulnerability as part of its research into a limited series of targeted malware attacks against Windows XP systems. Researchers found attackers were using a new vulnerability that was potentially wormable. The company planned a Webcast on Friday to discuss the release. Holding Out Hope
This advisory has all the makings of a worm, according to Tyler Reguly, a security engineer for nCircle. "The difference between this and slammer or code red, or at least I hope it's a difference, is that hopefully there aren't too many Internet-facing machines listening on ports 139 and 445," he said. "If it is facing the Internet, that means that not even a simple home router is used, and that thought scares me."
Reguly could see this used by an employee inside a company. For example, if a company's internal security isn't adequate, a disgruntled employee with the proper skill set could take advantage of the vulnerability.
Security researchers are warning IT administrators to keep in mind that a patch is released out-of-band for a reason. Like Microsoft, security researchers suggest patching this immediately. According to Microsoft and Symantec, the problem is being seen in limited, targeted attacks. However, that could escalate if systems are left unpatched.
The Threat of Identity Theft
"While the first thing that comes to mind with a patch is protection, malicious individuals are thinking, 'Yes, we can see where the vulnerability is.' This means it's easier for hackers to develop exploit code to take advantage of this vulnerability," Reguly said.
Security researchers are also considering what this could mean to smaller retailers focused on PCI compliance. Reguly worked for a small business in the past that had SBS 2000 directly connected to the Internet, and traffic was being routed through that server.
"Setups like this do exist and they are vulnerable," he cautioned. "Unpatched retailers without adequate security practices could leave their clients open to identity theft."

Reactivate folder options.........
Now-a-days different types of viruses are there which affects your computer indirectly, like you cannot access some of the computer options. A similar symptom is sometimes folder options in your PC may get disabled by some virus and after removing the virus, you can not use folder options. So here i am sharing some tricks to activate folder options again
But before doing this first remove that virus from your computer using some good antivirus.Process 1:
type “regedit” in run command and hit enter
find any of the following keys:
User Key: HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Policies\ Explorer
System Key: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Curr entVersion\Policies\ Explorer
Value Name: NoFolderOptions
Data Type: REG_DWORD (DWORD Value)
Value Data: 0 = show options, 1 = hide options
Process 2 :
do: start -> Run -> Type gpedit.msc -> hit enter -> User Configuration -> Administrative Templates -> Windows Components -> Windows Explorer -> select Removes the Folder Options menu item from the Tools menu. -> Right click: -> Properties -> Disable -> Apply
done!!

SecureMac is reporting that it has discovered multiple variants of a new Trojan horse in the wild that affects Mac OS X 10.4 and 10.5.The Trojan horse is currently being distributed from a hacker website, where discussion has taken place on distributing the Trojan horse through iChat and Limewire.
The Trojan horse runs hidden on the system, and allows complete remote access to the system. It can also transmitsystem and user passwords, and can avoid detection by opening ports in the firewall and turning off system logging.
The Trojan horse, named AppleScript.THT, can log keystrokes, take pictures with the built-in Apple iSight camera, take screenshots, and turn on file sharing. The Trojan horse exploits a recently discovered vulnerability with the Apple Remote Desktop Agent, which allows it to run as root.

So heres my tip in avoiding this:
1st: Always make all files visible like system and also hidden files with their extension shown.
Go to Windows Explorer > Tools > Folder Option > View
* Enable Show Hidden File
* Disable Hide Extensions for know file type
* Disable Hide Protected OS files.2nd: Never Use the Autorun functionality in Windows
whenever you put a disk(flash, memory card, usb drive devices and other form of removable drive) it is always a practice to scan it first. but to avoid being the first to be infected by a wild one, always use Windows Explorer to browse the files. Use the left side(Folder Window), to browse the files. Whenever you see an autorun.inf file, delete it! remove the disk and insert it again to avoid clicking it.
3rd: Always update Virus database!
Always note that all this information are applicable at your own risk.This site is not responsible for any malfunction occured during the process.
