Do You Know Windows Defender Has An Offline Version?

Written on October 14th, 2012 by sanklpno shouts

Windows Defender, formally known as Microsoft AntiSpyware, is Microsoft’s security weapon to prevent, remove, and quarantine spyware in Windows. It’s by default enabled and included in both Windows 7 and Windows 8. But in Windows 8, it’s reinvented with added anti-virus feature, powered by Microsoft Security Essentials. It’s included within the Windows package, and is intended as the default anti-virus program on Windows 8 machines.

But do you know it also has a standalone version that can be run independently without Windows?

Windows Defend Offline can be your secret weapon fighting with malicious, and rootkits that are installed but so hard to find by your installed anti-virus program on your computer. It’s still heavily based on the definition files to identify the threats. Therefor, in order to make it work effectively, it’s important to always have the most up-to-date definitions installed.

To start using Windows defender Offline, just follow these 3 basic steps:
1. Download Windows Defender Offline from here and create a CD/DVD, or USB flash drive.
2. Restart your computer using the Windows Defender Offline media.
3. Scan your PC, and remove any malware that is found from the scan.

YUMI – Multiboot USB Creator (Windows)

Written on August 13th, 2012 by sanklpno shouts

YUMI (Your Universal Multiboot Installer), is the successor to MultibootISOs. It can be used to create a Multiboot USB Flash Drive containing multiple operating systems, antivirus utilities, disc cloning, diagnostic tools, and more. Contrary to MultiBootISO’s which used grub to boot ISO files directly from USB, YUMI uses syslinux to boot extracted distributions stored on the USB device, and reverts to using grub to Boot Multiple ISO files from USB, if necessary.

Aside from a few distributions, all files are stored within the Multiboot folder, making for a nicely organized Multiboot Drive that can still be used for other storage purposes.
Creating a YUMI Multiboot MultiSystem Bootable USB Flash Drive
YUMI works much like Universal USB Installer, except it can be used to install more than one distribution to run from your USB. Distributions can also be uninstalled using the same tool!

Actual size of a 500GB hard drive

Written on July 25th, 2012 by sanklpone shout

Actually, the 1000 vs. 1024 thing does not *really* apply to hard drives, only memory.

When discussing memory, a “gig,” is really a Gibibyte (1024^3 bytes, abbreviated GiB), not a Gigabyte (1000^3 bytes, abbreviated GB). Computers “think” in binary, so everything is numbers that can be factored only by 2.

This is *not* the case with storage. Manufacturers can make storage in any size — not just sizes factorable only by 2. So, a 500 GB hard drive is 500 Gigabytes (500 x 1000^3 bytes).

In theory — in practice, hard drives are rated by “size class.” So a 500 GB hard drive is in the 500 GB size class, which means *pretty close to* 500 GB.

To add to the confusion, most operating systems use the JEDEC standard definition of GB, in which a GB is 1024^3 bytes!

So, your 500 GB hard drive should have a size of

500,000,000,000 bytes.

Your OS will recognize it as a 465.7 GB drive, but, by that, it means

500,000,000,000 bytes

Because when your OS says GB, it really means GiB.

 

***************

This makes a gigabyte 1,073,741,824 bytes. Now if we compare that to the 1,000,000,000 bytes that the HDD manufacturers use,
you can see that there is over a 7% difference! Therefore Windows will report the hard disk as being approximately 7% smaller than the hard drive
manufacturer’s quoted size.

then don’t forget Another factor that can mean you have slightly less space on your HDD than quoted is because the file system that your computer
puts on the hard drive takes up space which is not available for use for storing data

How To Disable a USB Flash Drive (Mass Storage Devices Only)

Written on July 25th, 2012 by sanklpno shouts

Whenever you insert a USB flash drive into your computer, the flash drive is detected automatically by Windows and then opened. Here I am going to show you how to stop your USB Flash Drives Mass Storage Only through registry.

This trick can also be done through My Computer by using Device Manager but that one stops all the USB connections. This is not recommended.

So are you ready to start?

Here we go.

Click Start Menu > go to run command and type “regedit” without quotes. Registry Editor will open.

  1. Expand the HKEY_LOCAL_MACHINE folder then SYSTEM >CURRENT CONTROLL SET > SERVICES >USBstor, located at the left pane.
  2. Find “Start” in the right pane with the blue icon.
  3. Double click “Start”. A box titled “Edit DWORD value” will open.
  4. Write down “4” in the “Value Data” Field. Illustration 1.1
  5. Click OK and then close the Registry Editor.

Your USB flash drive is now disabled. Whenever you insert a flash drive, Windows won’t detect it and will not open it.

To enable it again, repeat steps 1 through 4 and then change the value to 3. The default value for enabling a USB flash drive is 3.

Note: Performing this trick will only Disable USB Mass Storage devices and will not affect other USB Devices such as USB Keyboard, USB Mouse, Scanner, Printer etc….always backup your registry to prevent losing your valuable data.
