Top 10 keyboard shortcutsUsing keyboard shortcuts can greatly increase your productivity, reduce repetitive strain, and help keep you focused. For example, highlighting text with the keyboard and pressing Ctrl + C is much faster than taking your hand from the keyboard, highlighting the text using the mouse, clicking copy from the file menu, and then putting your hand back in place on the keyboard. Below are our top 10 keyboard shortcuts we recommend everyone memorize and use.
Ctrl + C or Ctrl + Insert
Copy the highlighted text or selected item.
Ctrl + V or Shift + Insert
Paste the text or object that's in the clipboard.
Ctrl + Z and Ctrl + Y
Undo any change. For example, if you cut text, pressing this will undo it. This can also often be pressed multiple times to undo multiple changes. Pressing Ctrl + Y would redo the undo.
Ctrl + F
Open the Find in any program. This includes your Internet browser to find text on the current page.
Alt + Tab or Alt + Esc
Quickly switch between open programs moving forward.
Tip: Press Ctrl + Tab to switch between tabs in a program.
Tip: Adding the Shift key to Alt + Tab or Ctrl + Tab will move backwards. For example, if you are pressing Alt + Tab and pass the program you want to switch to, press Alt + Shift + Tab to move backwards to that program.
Tip: Windows Vista and 7 users can also press the Windows Key + Tab to switch through open programs in a full screenshot of the Window.
Ctrl + Back space and Ctrl + Left or Right arrow
Pressing Ctrl + Backspace will delete a full word at a time instead of a single character.
Holding down the Ctrl key while pressing the left or right arrow will move the cursor one word at a time instead of one character at a time. If you wanted to highlight one word at a time you can hold down Ctrl + Shift and then press the left or right arrow key to move one word at a time in that direction while highlighting each word.
Ctrl + S
While working on a document or other file in almost every program pressing Ctrl + S will save that file. This shortcut key should be used frequently anytime you're working on anything important.
Ctrl + Home or Ctrl + End
Move the cursor to the beginning or end of a document.
Ctrl + P
Print the page being viewed. For example, the document in Microsoft Word or the web page in your Internet browser.
Page Up, Space bar, and Page Down
Pressing either the page up or page down key will move that page one page at a time in that direction. When browsing the Internet pressing the space bar will also move the page down one page at a time. If you press Shift and the Space bar the page will go up a page at a time.

How to Protect Your Computer From Viruses

With millions of computer users browsing the web at any given time, there are plenty of targets for malicious coders. While computer experts don’t always know why coders choose to build harmful computer programs, the fact is that it happens all the time. Computer viruses can steal personal information, interfere with normal operations, attract spam and even shut down your computer’s hard drive. Protecting your computer is critical for browsing success.

Start With the Basics

Most computer systems come with security features already in place. For example, the Windows operating system is packaged with Microsoft Windows Security Center. When you first open, boot up and register a new computer, you should make sure that this program is functioning. It will give basic protection against spyware, viruses and malware. In addition, a basic firewall is built into this program, providing additional protection and stops for potentially harmful programs. Upon activation, don’t be surprised if your security system needs immediate updating. Software that protects your computer needs regular and consistent updating to stay useful. Viruses are constantly being generated and the several-month lag between when your computer was made and when you first started using it can mean that the database the security system is loaded with is severely out-of-date.

Upgrade to Meet Your Needs

Many people operate computers for a long time with only basic protection in place. However, heavy computer users or those who have risky browsing habits can sometimes benefit from upgrading their virus, spyware and malware protection, as well as using a fuller-featured firewall; this is especially important if you use a networked computer system. Basic or free virus protection will still scan and update for viruses. Paid programs, however, offer more features, including ease-of-use and convenience features. The most important thing is to verify the publisher and make sure you are getting what is promised. Most well-known virus protection programs, such as AVG and Norton Security, have reviews available to help you make your choice.

Learn About Spyware Risks

Spyware creates risks that many computer users are not aware of. If you are only protecting against viruses, you could be leaving your computer open to damage. Most people are familiar with spyware that initiates and attracts annoying ad programs. Spyware, however, can be much more malicious as well. Your shopping habits can be tracked by spyware. While not exactly harmful, some people consider this a breach of privacy. The worst spyware programs interfere with normal operations and can even track what you type, sending personal information to people who want to steal your identity. Some spyware redirects your browser to different web addresses, increasing your risks of virus infection and fraud.

How Viruses Work

The main difference between spyware and viruses is how they are spread. A virus reproduces itself and attaches to any document that the computer sends, while spyware can be stored as a cookie or tracking code. A virus is most often found traveling with a piece of computer software, such as a document, picture or piece of music. When dealing with email, it is necessary to open an attachment to become infected, indicating that, in most cases, the computer user must somehow invite the malicious software to replicate on their system. Of course, most people have no idea it is there or what is happening. Some of the sneakiest and most harmful viruses actually masquerade as virus protection software, making them extremely hard to detect. Because of this, it’s crucial to be familiar with your particular virus protection program and know what it looks like and what the normal scripts and prompts are during operation. Viruses do some of the same things that spyware does; they just accomplish it differently. An active virus can steal personal information, generate ads or shut down your system, including the very virus protection programs that can fix the issue.

Take Steps For Protection

Like anything, the best way to protect against viruses is to be educated. Become familiar with what malicious software may look like. If you get an email or are asked to download a file that you don’t recognize or looks suspicious, do your homework. Research virus protection, spyware, malware and firewall programs and use them to their fullest capacity. Set the software to update and scan automatically to make sure that the system is constantly monitored. In addition, regularly check on the databases published by various virus protection services; many will provide lists of symptoms and risks, as well as the standard way the file gains access for no cost to the public.
