A Simple Way to Make Your PC Fast
Slow computers are one of the biggest problems facing computer users today Not only does a slow computer make you extremely frustrated, but it also prevents you from enjoying your computer and even doing work on it It’s a terrible problem which affects millions of machines world wide, but luckily, there’s a solution . .You see, almost every slow computer in the world has a simple problem that’s causing the decline in speed - the registry The registry is the core database for Windows, and is actually one of the most important parts of your system It acts like a memory for all your options and settings on your computer, allowing Windows to store everything from your latest emails to your desktop wallpaper in there and then retrieve it at another time . .Because the files inside this database are needed so much by Windows, it’s constantly updating and using them Each time you use your PC, you can end up having 100’s of registry files all being processed without you even knowing This is okay, but the reason why it’s responsible for slowing your computer down is simple - because Windows is using these files so much, it often gets confused and actually corrupts the same files that it needs . .When your computer corrupts registry files, it actually makes them harder to read, which in turn makes your computer run slower as it tries to access them The truth is that one or two of these bad files are okay - they only slow your PC down a little bit - but the real problems start when your PC gets 1,000’s of these files all slowing it down When this happens, your PC just gets slower and slower as it collects more corrupt files every day . .Luckily, to fix this and to make your PC fast, you simply need to fix these corrupt registry files However, because the registry is such a big database, you need to rely on a special tool to do it for you These tools are called registry cleaners and are pieces of software which actually scan through the entire registry and check every file If it then finds a corrupt file, which needs fixing, it will then fix that file or replace it .

How To Prevent Thieves From Stealing Your PDF Ebooks!
There are 2 main options for protecting your PDF file: OPTION 1: Use Adobe Acrobat’s basic protection. Adobe Acrobat allows you to set basic protection for your PDF document. This includes: * allow/disable the ability to copy text of document * allow/disable printing of file * allow/disable changing document * require password to open document (Yes their password protection was broken a few years back, but it’s still adequate protection and will keep out most people.) Ideally, to use this option you should use Adobe Acrobat, however the high cost may put that out of reach of many. Fortunately, there are MANY, MANY inexpensive PDF creators that will allow you to also set some of these permissions. Such as: http://www.pdf995.com http://www.pdffactory.com http://www.deskpdf.com There are also some standalone applications like: http://www.verypdf.com/encryptpdf/index.htm Overall, option 1 is what I call “static protection”. Meaning, once you choose the security and then distribute the file, you cannot change the security for those files that are already distributed. For example, you distribute a file to Client A in December. In January, your relations with the client become strained and you no longer want them to have access to your file. Unfortunately, with static protection, you cannot change their access permissions. It is already “set”. Though this option may allow you to prevent copying text within the file, it does NOT prevent a user from copying the entire file and redistributing it to others. Though it may allow you to require a password to access the file, the password can be easily passed around so anyone can have access. So it’s not entirely secure and easily circumvented. If protection of your document is critical, you should boost protection using additional mechanisms. OPTION 2: Use a third party protection system. This option includes systems that offer “real time” control over your document. “Real time” means that you have the ability to change or alter the document security after it has been delivered to the end user. This is what I choose to focus on as it provides the greatest amount of security and post-distribution control. Some just offer basic lock and unlock ability, while others go into more extensive PDF settings that can be altered at any point. Here are some things you should be looking for when evaluating a PDF protection system. 1. Does the system offer complete protection? This the first thing you should look at because if the protection is not up to par, move on! You will never even get to the other points. When evaluating protection features, make sure you check each feature out for yourself and don’t always take the company’s word about protection. Many times I have seen companies advertising certain protection features on their website, but in testing, the product doesn’t seem to do what is claimed. So, always check first. For PDF files, there are some basic areas that any adequate system must protect against. In order to be totally protected, the PDF security system you use MUST: * Prevent saving a copy of file. * Prevent emailing of file and exporting or extracting pages from file * Prevent copying of file from the TEMP folder * Prevent copying file and text to the clipboard * Prevent redistilling of the file * Prevent unlimited, uncontrolled printing of file * Prevent access to file without permission * Watermark all printed pages If any system that you look into does not cover these, I recommend that you move on to something that does. 2. Can you afford it? If the system passes the security test, the next thing you should look at is the cost of the system. Is it within your budget? Can you justify the price of this type of service? Do you buy the entire system and run it on your server, or is it a hosted service that charges you a monthly fee. There are pros and cons of both. If you run the system on your server then you will avoid monthly fees, but these types of systems usually require extensive programming and integration work which can increase your overall costs and take weeks to months before you get up and running. If you choose a third party system that is hosted by another company, you avoid the integration issue as most of these services can get you up and running in minutes to hours. 3. Does the system offer auto-distribution? Does it automatically deliver your document to your customers and clients hands-free? If so, does it integrate with your payment system and/or shopping cart? 4. Is the system flexible? The next thing you should look at is the flexibility. Does it allow you to tweak and modify the security options to fit your unique requirements? The ability to customize things such as program icons, customer download emails, thank you pages, etc. makes a big difference. 5. Is there any customer support? What kind of support and help will you receive when you purchase the product or service? Is their any documentation of all features and uses? What good is having the best system if you don’t know how to use it? 6. Is the Company reliable? Does it protect my data? Is this company reliable? Do you feel that the the company will shut down, thus leaving your documents inaccessible and/or unprotected? Ask them what measures do they provide to ensure that your information remains protected in this event? Do they back up your data? If so, how often? 7. Can you demo the system? Most companies offer a trial or demo period for free or a small fee. You should always try the system out to see it “in action”. Set it up to do exactly what you are looking for and see if it works the way you need. Never sign up or purchase something that you have not yet tested. 8. Other questions? Those are the major criteria, of course there are other things that you may want to consider such as: * What is their cancellation/refund policy? Do they require a contract or can you sign up for a month to month service? * Does their system use Acrobat Reader or another PDF viewer? If they use Acrobat Reader, do they have an Adobe DRM license which is required for all Acrobat reader security systems? * Does it allow you to contact your database of users/clients * Can you export your user database There is a lot to consider when deciding on a PDF protection system. My advice is Do NOT rush into it. Because once you choose a system and start distributing files using that system, you are stuck with it. File Secure Pro is a document protection and delivery system that allows users to securely distribute, monitor and control usage of their intellectual property. learn more at <a href="http://www.protectyourfile.com/" title="http://www.protectyourfile.com/" target="_blank">http://www.protectyourfile.com/</a> If you distribute important information online, File Secure allows you to start protecting your information within minutes.

FTP Servers and Security - Three methods that Secure FTP Servers use
FTP (File Transfer Protocol) has been the basis for file transfer since the dawn of the internet. The truly remarkable feature about FTP was that it was operating system independent. Files could be smoothly transferred between Unix, Windows and any other operating system. The other cool feature about FTP was that a simple validation mechanism consisting of a username and a password could be used to limit access to files. However, the actual data itself was transferred unencrypted and it was easy to intercept and listen in on an FTP connection. The internet itself had very minimal security built into it. Consisting of many smaller independent networks that stretched across the globe, the path that a data packet took to get from point A to point B was unpredictable. With the popularity of the internet, it became essential to be able to transmit many types of critical data with some amount of security. Netscape Communications solved the security problem on the internet by developing the Secure Sockets Layer Protocol (SSL) which used public key cryptography to encrypt data transmitted over the internet. This is still the widely accepted security mechanism and is implemented by all web browsers. FTPS Secure File Transfer Modifications to the FTP protocol were proposed to incorporate the use of SSL for encrypting file transfers over the internet. The modified mechanism is referred to as FTPS. In order to maintain backwards compatibility with the original file transfer protocol, an FTPS connection could either be explicit, where the connection between the client connection and the server starts out as regular FTP and then negotiates a secure connection, or implicit where the connection starts out being encrypted. HTTPS Secure File Transfer Since a web browser is already capable of public key cryptography, simple downloads and uploads can be performed directly through a web browser using the HTTPS protocol. This means that special FTP Client software is not required. SFTP Secure File Transfer The Secure Shell protocol also known as SSH was developed by Tatu Ylonen to enable secure access to remote shells using public key cryptography and replace Telnet and other non secure shells. This protocol has since evolved to also support a file transfer mechanism known as SFTP. The main advantage of this mechanism is that it did not require the opening of an additional data channel connection for transferring files. All of these three methods of secure file transfer are based on public key cryptography and all of them are equally capable of securing the transfer of critical files across the internet. The only drawback of these methods is that there is a data overhead associated with encrypting files. There is also a performance overhead associated with encrypting the files at the source and decrypting them at the destination. Because of this, system administrators sometimes use regular FTP for file transfers within a secured internal network. However, for transferring files over the internet, this is a small price to pay in exchange for the guarantee that sensitive files reach their destination without being intercepted or tampered with.Okay, you now know about the three types of secure ftp servers.
