On a Dell E4300 laptop what does the button to the left of the power button do?

It is the "Latitude On" button, which is supposed to give you a much quicker start, and much much longer battery life (with many of your same apps) by not loading Vista, but rather loading a version of Linux which is hard coded on your chip. http://en.wikipedia.org/wiki/Latitude_ON Early versions of E4300's (like mine) only have it in a "reader" mode, but upgrades are on their way It seems like an attempt to get the best of both worlds ... the low-power perks driven by UMPCs, and the high power features common on Vista machines. Great idea! by the mobile learning team at www.m-learning.org

How do you know if the emails you send to somebody is going into their spam or trash pile?

Unfortunately, one cannot be entirely certain of whether one's emails are being received; at least, not through the email system itself. Depending on the precise nature of the email, there are a few ways one could use to check.

If one expects a reply to the email, for instance, then naturally receiving such a reply would imply that the message was received and not sent to a spam folder. One could ask for a verification-of-receipt message specifically when sending an email.

Another way to test whether messages are being received properly and not being sent to a spam folder is to use a confirmation email. Many Web sites use these: an email with a confirmation code or link is sent. If the recipient clicks said link, then they have received the message.

How does computer get infected with rogue antivirus software?

Your computer gets infected by rogue anti virus software by the user allowing someone or something to download itself. This is called social engineering or the user's computer is already infected and the malware present downloads more malware including rogue antivirus software. Today anti malware experts are cracking down on hackers and other exploits in the cyberworld. In many cases th security is so good that even the most experienced people technically have a very difficult time being malicious. To around this malicious code writers take advantage of social engineering. Instead of being technical and finding holes or vulnerabitlitys in operating systems or programs cybercriminals just let a user let them in. You know when you visit a site or try to download data internet explorer will pop with a security warning. Well some people click yes download and so on. Thus making the criminals job a lot easier. Computers will also download rogue antivirus when already existing malware (malicious code) sends information about your computer to download more malware. Why does this happen? Cybercriminals know that after a while users will realize their machines are infected and therefore disinfect them. However if more and more malware is downloaded it will make fixing the machine and in many getting help very difficult.
To fix malware problems visit download.com and search for AVG 8 Free. Trust me it is an extremely good piece of software. It fix the problem totally 99 % of the time. Hope you find a solution to your problem.

I have found that AVG and other antivirus programs do not work very well with rogue antivirus and maleware programs. There are many different variations of these rogue programs and they usually drop trojans and worms with them. The programs that work effectively are maleware bytes antimalware and super antispyware. As soon as you know you have been infected you must start scanning with these programs immediately, as the infections start to lock your computer down. Meaning you may not be able to open things such as the registry, task manager, any programs, etc....
