>Cant See Secure Sites
>
Fix the problem with seeing them secrue sites (banks or online stores) i found this very usefull to me at my work.
Any way… what u need to do is make a new notepad file and write in it the followng DLL’s.. just copy-paste these
regsvr32 SOFTPUB.DLL
regsvr32 WINTRUST.DLL
regsvr32 INITPKI.DLL
regsvr32 dssenh.dll
regsvr32 Rsaenh.dll
regsvr32 gpkcsp.dll
regsvr32 sccbase.dll
regsvr32 slbcsp.dll
regsvr32 Cryptdlg.dll
and save it as > all file types, and make it something like securefix.bat.
then just run the file and ur problem shuld be gone.
>How Data Stored In a CD

Abstract
You can fit on a S/VCD without over burning:
– approx. 735 MB of MPEG data onto a 74min/650MB disc
– approx. 795 MB of MPEG data onto an 80min/700MB disc
You can fit on a CD-ROM without over burning:
– approx. 650 MB of data onto a 74min/650MB disc
– approx. 703 MB of data onto an 80min/700MB disc
Introduction
Let us ignore for now the terms of megabyte for CD capacity and try to understand how the data is stored on a CD.
As well all know, the data is stored digitally as binary data. This means, however the actual information is actually kept on the disc, this information is in the form of “1”s and “0”s. Physically, the information on a CD is as pits on a thin sheet of metal (aluminum).
An a CD-R disc, the data is physically on an organic dye layer which simulates the metal layer on a real pressed CD.
How is the information structured
Now, on the CD, the information isn’t just organized from beginning to end willy-nilly. Otherwise, it would be really hard to find a useful piece of information on the CD.
Rather, the information is organized in sectors. Consider a sector as like a page in a book. Just like you are able to quickly find something in a book if you know the page number, you can quickly find something on a CD if you know the sector number.
Now, remember that the CD was original made to hold audio data. It was decided, that the CD would would 75 sectors per second of audio. Although I cannot guess where this number comes from, it is quite appropriate for the audio CD. It means that you can “seek” an audio CD accurately to 1/75th of a second — which is more than enough for consumer purposes.
Now, with this in mind, we can work out the total data capacity of user data for 1 sector.
The total data capacity of user data of 1 sector on a CD
CD audio uses uncompressed PCM stereo audio, 16-bit resolution sampled at 44.1 kHz.
Thus 1 second of audio contains:
16 bits/channel * 2 channels * 44100 samples/second * 1 second
= 1411200 bits
= 176400 bytes
Since there are 75 sectors per second
1 sector
= 176400 bytes / 75
= 2352 bytes
One sector on a CD contains 2352 bytes max.
—————————————————————-
The concept of different MODES and FORMS of burning
Now, audio CD was well and good, but the medium would become much more useful if you could store other data on the disc as well. This became to be know as CD-ROM of course.
Now, the audio-CD uses the ENTIRE sector for audio data.
However, for CD-ROMs this caused a problem. Simply, CDs and the CD reading mechanisms were not 100% faultless. That is, errors (indeed frequent errors) could be made during the reading. For audio CDs, this does not matter as much as you could simply interpolate from the adjacent audio samples. This will obviously NOT DO for data CDs. A single bit error could lead to a program being unexcitable or ruin an achieve file.
Thus, for CD-ROMs, part of each sector is devoted to error correction codes and error detection codes. The CD-R FAQ has the details, but in effect, only 2048 bytes out of a total of 2352 bytes in each sector is available for user data on a data CD.
This burning mode is either MODE1 or MODE2 Form1.
MODE2 Form2 sectors of VCDs and SVCDs
Now, for VCDs and SVCDs, the video tracks do not necessarily require the robust error correction as normal data on a CD-ROM. However, there is still some overhead per sector that is used for something other than video data (e.g., sync headers).
S/VCDs video tracks are burnt in what is called MODE2 Form2 sectors. In this mode, only 2324 bytes out of a total of 2352 bytes in each sector is available for user data.
This is MUCH MORE than for CD-ROMs, but still less per sector than audio CD.
—————————————————————-
The disc capacities of CD-ROMs, audio-CDs and VCDs
Now, obviously what ultimately determines the capacity of a disc is the total number of sectors it contains. This is similar to the total number of pages in a blank exercise book (if you recall the book analogy).
The secondary determinant is the burning mode of the disc.
For audio CDs, it is as if you could fill each page from top to bottom with audio data as the entire sector is used for audio data.
For CD-ROMs, it is as if you need to first rule a margin and then leave the bottom part of each page for footnotes (headers + ECC + EDC). The amount of text you can actually write per page is then less due to these other constraints.
For S/VCDs, we still need to rule a margin on the page, but we don’t have to worry about the footnotes (headers). We can fit MORE text than a CD-ROM, but less than an audio-CD.
Now remember, 1 second on a CD = 75 sectors.
Thus:
– 74 min CD = 333,000 sectors
– 80 min CD = 360,000 sectors
Data capacity in Mb for an audio-CD
74 minSearch Amazon.com for sony bloggie touch
= 333,000 sectors * 2352 bytes / sector
= 783216000 bytes
= 746.9 Mb
80 min
= 360,000 sectors * 2352 bytes / sector
= 846720000 bytes
= 807.5 Mb
Data capacity in Mb for a CD-ROM
74 min
= 333,000 sectors * 2048 bytes / sector
= 681984000 bytes
= 650.4 Mb
80 min
= 360,000 sectors * 2048 bytes / sector
= 737280000 bytes
= 703.1 Mb
Data capacity in Mb for a S/VCD
74 min
= 333,000 sectors * 2324 bytes / sector
= 773892000 bytes
= 738.0 Mb
80 min
= 360,000 sectors * 2324 bytes / sector
= 836640000 bytes
= 797.9 Mb
Conclusions
As you can see, the often quoted capacities of 650MB and 700MB refer to CD-ROM capacities.
Due to the fact that S/VCDs use a different burning mode where MORE of each sector is available as user data, the relatively capacities are HIGHER.
Now, since S/VCDs are not composed of PURELY video tracks and have some unavoidable overheads, the actually total capacity left for video tracks is a few Mb less for each disc (about 735 Mb for 74min discs and 795 Mb for 80min discs). This is where the often quoted capacities of 740MB and 800MB come from. They are quite accurate.
All these capacities are available BEFORE overburning. Overburning is where you burn MORE sectors than the disc is rated for. If you overburn, you can typically achieve about 1-2 minutes of additional capacity (depending on your drive and media).

>How to Right bin using NERO
Posted by nck12 in Computer, DVD Writer, Nero on February 14, 2011
>
You’ve downloaded a *.BIN file, but there was no *.CUE file associated and you still want to burn the *.BIN file using Nero
Your options are:
1) Create yourself a *.CUE
2) Convert the *.BIN to an *.ISO
3) OR use Nero to burn without the *.CUE file!!!
Yes, that’s possible… just follow these steps and you will be sorted. No need for *.CUE files anymore
Ok, here we go…
1) Start Nero
2) File -> Burn Image
3) Browse to the *.BIN file that you want to burn and open it
4) A window saying “Foreign Image Settings” will open
5) Check the settings. They should be as followed:
* Type of image: leave it to Data Mode 1
* Select the Raw Data check box
Note ->> The block size will change automatically from 2048 to 2352
* Leave Image Header and Image Trailer unchanged and set to 0
* Leave “Scrambled” and “Swapped” check boxes unchecked
6) Click on burn!
7) Enjoy
This tut was for Nero 5.x.x.x, I was told that “Burn Image” is under “recorder” in Nero 6. The rest of the steps should be the same.

Here are some basics maintenance tasks you can do today to start improving your computer’s security. Be sure you make these part of your ongoing maintenance as well.
* Sign up for software update e-mail notices. Many software companies will send you e-mail whenever a software update is available. This is particularly important for your operating system (e.g., Microsoft VV!|VD0VV$® or Macintosh), your antivirus program, and your firewall.
* Register your software. If you still have registration forms for existing software, send them in. And be sure to register new software in the future. This is another way for the software manufacturer to alert you when new updates are available.
* Install software updates immediately.
When you get an update notice, download the update immediately and install it. (Remember, downloading and installing are two separate tasks.)
An ounce of prevention
A few simple steps will help you keep your files safe and clean.
* Step 1: Update your software
* Step 2: Backup your files
* Step 3: Use antivirus software and keep it updated
* Step 4: Change your passwords
Developing ongoing maintenance practices
Now that you’ve done some ground work, it’s time to start moving into longer term maintenance tasks. These are all tasks that you should do today (or as soon as possible) to get started. But for best results, make these a part of a regular maintenance schedule. We recommend setting aside time each week to help keep your computer secure.
* Back up your files. Backing up your files simply means creating a copy of your computer files that you can use in the event the originals are lost. (Accidents can happen.) To learn more read our tips for backing up information.
* Scan your files with up to date antivirus software. Use your antivirus scan tool regularly to search for potential computer viruses and worms. Also, check your antivirus program’s user manual to see if you can schedule an automatic scan of your computer. To learn more, read our tips for reducing your virus risk
.
* Change your passwords. Using the same password increases the odds that someone else will discover it. Change all of your passwords regularly (we recommend monthly) to reduce your risk. Also, choose your passwords carefully. To learn more, read our tips for creating stronger passwords
.
Making a schedule
One of the best ways to help protect your computer is to perform maintenance regularly. To help you keep track, we suggest making a regular “appointment” with your computer. Treat it like you would any other appointment. Record it in your datebook or online calendar, and if you cannot make it, reschedule. Remember, you are not only helping to improve your computer, you are also helping to protect your personal information.

Editing the windows registry is one of the most powerful ways of manipulating you system settings, which is something that makes it equally dangerous.It is minefield filled with often cryptic configuration parameters which usually affect your system in ways you won’t even notice. it can completely mess up your system in such a way that you are unable to even boot into windows .Modify the right hardware settings, and your hardware gets boost, modify the wrong one, and you end up with a non- booting system.
Before you set up to d anything with the registry.
- If you are using the system restore /system protection feature in windows create a recovery point.
Common use of editing a registry is to remove applications from your startup sequence.Windows registry is like a virtual file system in which you have “keys” and values instead off folders and files.A key is reminiscent of a flolderina drive, a key can contain multiple name data pairs which can also be assigned a value the data in each name data pair is typed, It can only contain data of certain type.The data type contain String binary,DWORD,QWORD, Expandable and string and Multi string .

How To Secure Your Wifi Connection!
Posted by nck12 in Backlink, Computer, Create Backlink on December 10, 2010
Hello Friends,
I am posting this bcoz some losser who hacked open Wifi connection and email from there to claim bomb blast which happned in Varanasi, India.
many company and home users uses the wifi connection to access Internet. But they don’t secure their wifi connections & Reason is just ignorance. Beware hackers are in their way. I’ve some idea to secure ur wifi connection.
step 1:
Go to your wifi device setup. normally its ip address is 192.168.1.1
step 2:
Go to the wireless settings and find security tab.
step 3:
There You’ll see WEP encryption setting.. make it Enable.
step 4:
Make Encryption strength 128-bit
give a Network Key. It should be at least 10 cherector long. (i.e: 21gl@di@tor12)
Network key is like a password to your wifi connection. when ever you want to access the Internet you’ll need it.
so like password keep it secret.
give a strong password ….
now how to give a strong password? I’ll show you in my next post.
Till then enjoy.
