If you are really interested in retrieving lost data from digital devices like hard discs and memory cards for crime investigation purpose, you can consider earning a computer forensics degree as federal agencies and other detective agencies recruited people who have knowledge about computers and trained them for specific tasks regarding to this particular field of forensics. There are many universities and colleges have started running specialized courses for this field of study.

Most universities offer this particular course online, while some institutions offer traditional degree that requires candidates to attend lectures on campus. Here are the best universities that offer both online and off-line degree of this particular course:

The American Intercontinental University (AIU) is one of the most reputed universities offering such courses. You can earn one of the most reputed Bachelor’s degrees in computer forensics and a Master’s degree in Internet Security through the AIU. The Kaplan University provides degrees in computer crime and criminal justice. This university does not provide a Master’s degree program but they offer Bachelor’s degree course in this field of study. The Virginia College runs courses that would help you in earning a Master’s degree in Cyber Security. The University of Phoenix runs regular and online courses for associate degrees in Information Systems. Similar programs are run by the Colorado State University, offering associate degree in Information Technology, Bachelor’s degree in IT security and Master’s degree in Information technology. The Capella University also runs highly reputed online programs specializing in IT and Information systems.

The Security Shield Virus is a recently launched rouge antivirus program made by hackers from either Russia or Asia. It is a fake program that presents itself as a legitimate application and lures users into buying false upgrades. This virus can be obtained from suspect websites and rogue downloads, such as files obtained from Torrents. Sensitive personal information such as passkey codes to email, credit card and bank accounts are not safe from this virus and can be stolen. This is a highly destructive virus program and should not be trusted. If you feel that your PC has been infected by Security Shield, you need to delete it from your system right away; otherwise it can cause irreversible damage to your PC.



Security Shield is a malicious or malware program which uses actual software to attach itself in PCs. Files and applications can easily be disabled once the virus enters a system. This stubborn program would also be loaded onto a system each and every time a user boots his computer. A feature of this malware application is that it runs a false antivirus scanning program which would show fabricated results. Users would then be fooled into believing that their PC is at the brink of shutting down because of viruses and malwares. At the same time, Windows applications would also be negatively affected and slower, making it hard for users to navigate their PCs. The Security Shield virus would then offer a sham solution to unwitting users, a full service pack that is utterly useless.

One solution to this threat is through manual removal. This approach is time consuming and would require someone who has at least basic knowledge in computer processes. Your PC should be set to “Safe Mode”, since you cannot use Task Manager in Windows to disable the application. The crucial step in manually removing Security Shield is stopping the virus from running. This will prevent the malware from reversing or blocking attempts to have it removed. Once this is performed, you can proceed to removing all applications and programs the virus runs on. It should be noted though that the virus also places “hidden files” in systems, whose job is to reload the malware once it detects that it has been removed. These files need to be also removed otherwise the threat would continue to persist in one’s system or PC.

The fastest way to remove this virus is through the use of antimalware applications, tools created to thoroughly flush out viruses from computers. Frontline Rogue Remover is an excellent example. It is widely known to be one of the best in its category and class. This antimalware software is very easy to use and a copy can be downloaded from the Internet in minutes. If your computer cannot access the Internet because the virus has disabled its browsing features, you can just use an uninfected computer to download Frontline Rogue Remover and just move the copy back using a CD or USB stick.

The history of wireless networks and of wireless networking goes hand in hand. Without the discovery of technology such as the radio, wireless technology would not exist at all today. The history of wireless networking goes as far back as the 1800′s with the advent of radio waves. The advent of more technology grew throughout the years and expanded to what we communicated with today.

In 1888, a Hamburg, Germany born physicist named Heinrich Rudolf Herz produced his first radio wave ever. By 1894 this radio wave production became a way of communication. Telegraph wires were used to receive the radio waves in signal form. Herz opened the way for radio, television, and radar with his discovery of electromagnetic waves. An Italian inventor named Marchese Guglielmo Marconi then expanded the radius of radio wave sending to two miles, becoming the “father of the radio.” By 1899, this form of telecommunication could travel pretty far for its time. Marconi could send a signal 9 miles across the Bristol Channel. He eventually expanded the radius to 31 miles across the English Channel to France. By 1901 the communication area became immense. Marconi could send signals across the entire Atlantic Ocean.

World War II became a big stepping stone for the radio wave. The United States was the first party to use radio waves for data transmission during the war. This use of radio waves could have quite possibly won the war for the Americans. The use of radio wave data communication lead to a lot of speculation to whether the radio signals could be expanded into something bigger than it currently was. In 1971, a group of researchers under the lead of Norman Abramson, at the University of Hawaii, created the first “packet-switched” radio communications network entitled “Alohanet.” Alohanet was the first wireless local area network, otherwise known as a WLAN. The first WLAN was not much, but it was a large discovery. The Alohanet WLAN was comprised of seven computers that communicated to each other. In 1972, Alohanet connected with the WLAN system Arpanet on the mainland. This length of connect was ground breaking in telecommunications between computers.

The first types of WLAN technology used an interface in which became over crowded for communication. Small appliances and industrial machinery caused interference so the technology had to be updated. The second type of WLAN technology to be released ended up being four times faster than its predecessor at 2Mbps per second. We use the third format of WLAN today, though our current WLAN system runs at the same speed as the second system released.

In 1990, the 802.11 Working Group was established to work towards a WLAN standard for all computers to communicate from. In 1997, IEEE 802.11 was accepted as the standard data communication format for wireless local area networks. The technology continues to grow today. Governments and large corporations are constantly looking out for the latest and fastest standard to work from.

The expansion of wireless networking will likely continue for decades to come.
