Malware and Spyware
Malware Malware,à short forà maliciousà (or malevolent)à software, is software used or created by attackers to disrupt computer operation, gather sensitive information, or gain access to private computer systems. It can appear in the form ofà code,à scripts, active content, and other software. ââ¬ËMalware' is a general term used to refer to a variety of forms of hostile or intrusive software. This malware will operate invisibly, often without displaying itself in your Task Manager. To top it off, malware usually refuses to be uninstalled through your control panel, and requires special tools to delete them from your drive.Yes, this is a direct cousin to viruses, but with a broader portfolio of wicked intentions. Malware includesà computer viruses,à worms,à trojan horses,à spyware,à adware, and other malicious programs. However, some malware is disguised as genuine software, and may come from an official company website. Malware is often used against individua ls to gain personal information such as social security numbers, bank or credit card numbers, and so on. Left unguarded, personal andà networkedà computers can be at considerable risk against these threats.Various factors make a system more vulnerable to malware: * Homogeneity: e. g. when all computers in aà networkà run the same operating system; upon exploiting one, one can exploit them all. * Weight of numbers: simply because the vast majority of existing malware is written to attack Windows systems, then Windows systems are more vulnerable to succumbing to malware attacks. * Defects: malware using defects in the operating system design. * Unconfirmedà code: code from aà floppy disk,à CD-ROMà orà USBà device may beà executedà without the userââ¬â¢s permission. Over-privilegedà users: some systems allow all users to modify their internal structures. * Over-privilegedà code: some systems allow codeà executedà by a user to access all rights of that user. * Malwares affect networks easily because of the use of same OS. What does malware do? The most common malware functions are: 1. Malware steals your personal information and address book (identity theft and keystroke-logging). 2. Malware floods your browser with pop-up advertising. 3. Malware spams your inbox with advertising email. 4. Malware slows down your connection. 5.Malware hijacks your browser and redirects you to an advertising or a phishing-con web page. 6. Malware uses your computer as a secret server to broadcast pornography files. 7. Malware slows down or crashes your computer. Spyware Spywareà is a type ofà malwareà (malicious software) installed onà computersà that collects information about users without their knowledge. The presence of spyware is typically hidden from the user and can be difficult to detect. Some spyware, such askeyloggers, may be installed by the owner of a shared, corporate, orà public computerà intentionally in order to monit or users.While the termà spywareà suggests software that monitors a user's computing, the functions of spyware can extend beyond simple monitoring. Spyware can collect almost any type of data, includingà personal informationà likeà Internet surfingà habits, user logins, and bank or credit account information. Most spyware is installed without users' knowledge, or by using deceptive tactics. Spyware may try to deceive users by bundling itself with desirable software. Some spyware authors infect a system through security holes in the Web browser or in other software.When the user navigates to a Web page controlled by the spyware author, the page contains code which attacks the browser and forces the download and installation of spyware. Spyware also has the same effects as malware has. How to protect your computer from spyware and malware? Here is the checklist for detecting and destroying malware * Install two or three differentà anti-spyware programsà (ââ¬Å"spyware cleanersâ⬠) on your computer, and update their definition lists regularly.
