McAfee is a popular anti-virus and comprehensive computer security suite of programs primarily deployed on the Microsoft Windows Operating System (OS). McAfee protects computers from all types of malware, phishing, and other security threats. Unfortunately, when McAfee’s real time security options are enabled, it can prevent installation of some legitimate programs. It can also prevent the use of popular Peer-2-Peer applications used for online collaboration and file sharing programs. Many McAfee users face the task of figuring out how to temporarily disable the program. The steps for disabling stand-alone McAfee Read More

The file rtvscan.exe is a legitimate part of the Symantec Internet Security Suite, which was developed by the same makers of the popular Norton-Anti Virus software. Its main purpose is to execute virus-scanning in real time conditions. This means it can scan every file that enters your system against possible security threats or virus infections. Thus, being “real-time” would signify that it can monitor all process activities, file accesses, and even the registry for any sign of virus activity. This process is not a harmful file. Even if there are Read More

D-Link is a computer equipment brand that specializes in producing networking devices such as routers, modems, and network storage devices. D-Link routers, in particular, are often found in both residential and commercial environments and a wide variety of individuals use them to maximize the potential of their Internet access. D-link routers often contain two or more wireless antennas, WPA encryption, and multiple Ethernet ports. D-Link Default Password Like most wireless devices, all D-Link routers are equipped with a control panel that allows users to change their settings, configure the router Read More

ARJ password recovery options vary depending upon which version of ARJ was used to create the archive. Early version of ARJ utilized a simple XOR encryption scheme. Because the password is used to generate the encryption key, the difficulty of decrypting an ARJ archive depends directly on the length of the password which was used to encrypt the archive. For more information on ARJ’s XOR encryption, read Method of attacking arj encrypted files More recent versions of ARJ utilize a version of the Gost algorithm for strong encryption. ARJ XOR Read More

Credit cards use the Luhn Check Digit Algorithm. The main purpose of the Luhn Check Digit Algorithm is to catch data entry errors, but it does double duty here as a weak security tool. The Luhn Check Digit Algorithm For a card with an even number of digits, double every odd numbered digit (1st digit, 3rd digit, 5th digit, etc…) and subtract 9 if the product is greater than 9. Add up all the even digits (2nd digit, 4th digit, 6th digit, etc…) as well as the doubled-odd digits, and Read More

Diffie-Hellman is an asymmetric cipher defined in U.S. Patent 4,200,770 in 1977, the same year that IBM’s algorithm was selected as the Data Encryption Standard. The Diffie-Hellman patent expired on 6 September, 1997. The Diffie-Hellman algorithm is named after its creators: Whitfield Diffie and Martin Hellman. ElGamal is a variant of Diffie-Hellman which was invented by Taher Elgamal.      

New computer malware is discovered daily on the Internet. As computer security companies successfully combat emerging threats, computer virus authors grow more creative in designing attacks that take advantage of the many computer users that have not taken appropriate security measures or updated anti-virus software to defend against new attacks. Once a computer is infected, the infection should be removed as quickly as possible in order to prevent additional malware from being installed, making recovery more difficult. How to Remove Malware Step 1 – Download the Bleeping Computer, RKill application, Read More

Anonymous browsing is simply browsing the World Wide Web with most of one’s identity hidden. This is primarily done through what is known as an anonymous browser based proxy. These websites hide information such as the computer’s location and IP address when users use them to browse the web. For example, when the user tries to access something on a certain part of the web, the proxy will talk to that file as the user’s ambassador, maintaining the user’s privacy. The practice of anonymous browsing can also maintain the user’s Read More

The HotBar add-on is an add-on program for Internet Explorer that personalizes email, as well as the  functionality and visual appearance of browser applications. While performing the functions noted above, HotBar also makes multiple connections with “hotbar.com” and “reports.shopperreports.com”. Hotbar also monitors phrases the user enters into search engines and reports them to third parties in order to allow the user to be targeted by embedded ads, as well as targeted pop-ups. HotBar also disables certain pop-up blockers, and due to increased computational processes, slows browser speed and overall system Read More

Password hacking programs work by using a number of approaches to either decrypt or guess a working password. Three of the most common approaches that password hacking programs use are: Known Ciphertext Attacks Dictionary Attacks Brute Force Attacks The specific algorithm that the password hacking program implements depends on the password system’s design. Each password hacking program is usually designed to defeat one specific type of password protection. Cisco router passwords, Zip passwords, and Microsoft Word passwords are some examples. Known Ciphertext Attacks A known ciphertext attack uses cryptanalysis to Read More
