How to Properly Scan Your Computer for Malware ?
E N D
Malware - A Malware is a moniker for software that has been created with malicious intent. The three most common types of malware are viruses, worms, and trojan horses. These terms are often used interchangeably, but they are actually very different. Each is a type of malicious software, but they differ in how they infect and affect computers. Malware
Phishing - While not actually malware, phishing has recently become a real security concern. Users are directed to a seemingly trustworthy website and defrauded into giving up personal information, such as credit card details, passwords, etc. Anti-phishing measures have been implemented in the current version of most browsers including Internet Explorer 7, Firefox 2, Netscape 9, and Safari 3. The anti-phishing measures generally involve checking URLs against a list of known phishing websites.
How can I prevent my system from being infected? The two most important things you can do to ensure your system is secure: keep Windows Updates up-to-date and run a trusted antivirus program. Running Windows Updates will give you the latest security patches and prevent system vulnerabilities from being exploited. An antivirus program is the most reliable method of detecting and eliminating malware. Keep in mind that an antivirus program is only as good as its latest update, so the key to maximizing security is to allow it to automatically update and auto-protect.
Malware detection techniques - There are techniques used in detecting malware activities in the system . a. Static analysis detection technique - it is the procedure of analyzing software without executing it. During static analysis the application is break down by using reverse engineering tools and techniques, so as to re-build the source code and algorithm that the application has created. Static analysis can be done through program analyzer, debugger and disassembler.
Malware detection techniques - b. Dynamic analysis detection technique - The process of analyzing the behavior or the actions performed by the application while it is executing is called dynamic analysis. Dynamic analysis can be done through monitoring function calls, tracking the information flow, analyzing function parameters and tracing the instructions. Generally a virtual machine or sandbox is used for this analysis; the doubted application is usually run into a virtual environment. If the application behaves unusually it is categorized as malicious.
Malware detection techniques - c. Hybrid analysis detection technique - This technique is the combination of both static analysis and dynamic analysis. The procedure it follows it that it first checks for any malware signature if present in the code under inspection and then it monitors the behavior of the code. Hence this technique combines the advantages of both the above techniques.
