Keeping Your Inbox Free Of Spam

Although e-mail can be incredibly convenient, it also can potentially allow a flood of junk e-mail, or “spam” to come flooding into your inbox uninvited. Because this type of e-mail can harbor computer viruses and spyware, it is important to take steps to combat it so that your annoyance level will be kept at bay and your computer will keep running safely. Even if you only send e-mails to people that you know, this doesn’t necessarily mean that you will be be immune from the effects of spam. The reason for this is that experienced spammers use tools such as automated e-mail generators to help guess combinations of e-mails. Therefore, they don’t necessarily have to know your e-mail address in order to send spam to your inbox.

Furthermore, always take care when filling out any e-mail registration forms, whether you are intending to gain access to a message board, or try your luck by entering a contest. Although most such registration efforts are ultimately harmless, there are still other entities that will willingly sell their e-mail lists to marketers in return for a handsome profit. If you are on such an e-mail list, you may soon find that your inbox becomes littered with spam.

Finally, many current e-mail programs such as Gmail and Yahoo have spam filters that sort out the junk from the important messages, without you having to even click your mouse. That said, these programs aren’t perfect. If you are expecting an e-mail from someone, yet you’ve failed to receive it, always check your spam filter to make sure that it hasn’t been sent there. Most programs allow you to add certain addresses to your “white list,” effectively telling your e-mail program that the address is not spam and should never be placed in your spam folder.

Safeguarding Your Private Data At Public Terminals

Although many people do have access to a personal computer at home or work, the reality is that almost everyone will have to use a public computer terminal, at least from time to time. Public libraries and Internet cafes are popular hangouts for people who just need Internet access for a short while, or who are away from home. Keep in mind that if you don’t use common sense, your personal data can be compromised. However, fortunately, there are several things you can do that work well to protect your data, and are also quite simple to perform.

Ideally, avoid entering sensitive personal data online at all. If you are traveling though, it makes sense that you might need to log onto your bank’s website to check to see how much money you have in your account, so if this is the case, it probably can’t be avoided. Therefore, try to be discreet when typing in your password or user name. You may wish to type with one hand, while using the other to shield the typing hand from the view of others. If there is a checkbox marked “Remember me on this computer” or something similar, make sure that it is unchecked. If the web browser asks you if you want to save the password in the browser’s memory for future use, make sure that you decline.  Furthermore, when you view information online, check periodically to make sure that someone is not watching your activity over your shoulder.

Finally, when you are done using the Internet, the first thing you should do is make sure that you log out of any accounts that you have accessed. After you have done that, the next step is to clear your browsing history, cookies and active logins. The exact steps to take will vary by the type of browser that you use, but normally you can do it through your “Tools” or “Preferences” menu.

When people think about viruses, the only thing that comes to their mind is Windows based computer. They are not wrong to connect viruses to Windows based operating systems, but viruses are also found for other operating systems like Mac OS X and Linux based Operating systems. The problem when one faces while dealing with viruses is that these viruses come in different kinds with disguises that look like important system software. Hence it becomes impossible to save one self from viruses without knowing the different types. Of course you could install different antivirus that could do half the work for you, but you need to have a basic knowledge about the kinds of Viruses that use ingenious and sometime stupid means to infect computers.

One of the most common viruses are the Resident Viruses which make a permanent home in side the computer’s RAM. After making itself home here, it begins executing various programs in the system that corrupt system files and other processes. A few examples of these viruses are the CMJ, MrKlunky and Randex.

Direct action viruses are viruses that do not cause problems unless made to. These viruses take action only when a few conditions are fulfilled and only then it begins to replicate. This virus specifically target the AUTOEXE.BAT files in the Windows C drive. These are important system files that carry out functions when the system is begun.

Over write virus are the major causes of system crashes. These viruses completely wipe off information in the files which they infect, thereby making it un-recoverable. A few examples of these viruses are Trivial 88.D and Trj.Reboot. These are different from Boot viruses that affect the hard disk’s boot sector. Some examples of boot viruses are the AntiExe and the Polyboot.B files. Other viruses such as macro Virus disguise themselves as viruses that infect certain application macros.
