I was just thinking of briefing you people on malware
Malware= Malicious Software which means
A software containing a hidden code which is intended to damage your PC
Malware can be of any kind. Below are some types of malware
1.Virus:A computer virus attaches itself to a program or file so it can
spread from one computer to another, leaving infections as it travels.
Much like human viruses, computer viruses can range in severity: Some
viruses cause only mildly annoying effects while others can damage your
hardware, software or files. Almost all viruses are attached to an
executable file, which means the virus may exist on your computer but it
cannot infect your computer unless you run or open the malicious program.
It is important to note that a virus cannot be spread without a human action,
(such as running an infected program) to keep it going.
2. Trojan Horse:A Trojan horse is a program that contains malicious or harmful code inside apparently harmless programming or data in such a way that it can get control and do its chosen form of damage, such as ruining the file allocation table on your hard disk. A Trojan horse may be widely redistributed as part of a computer virus.
When a Trojan is activated on your computer, the results can vary. Some Trojans are designed to be more annoying than malicious (like changing your desktop, adding silly active desktop icons) or they can cause serious damage by deleting files and destroying information on your system. Trojans are also known to create a backdoor on your computer that gives malicious users access to your system, possibly allowing confidential or personal information to be compromised. Unlike viruses and worms, Trojans do not reproduce by infecting other files nor do they self-replicate.
3. Worm: Worms are generally considered to be a subset of viruses, but with key differences. A worm is a computer program that replicates, but does not infect other files: instead, it installs itself on a victim computer and then looks for a way to spread to other computers.
4. Adware: Adware are programs designed to launch advertisements, often pop-up banners, on host machines and/or to re-direct search engine results to promotional web sites. Adware programs are often built into freeware or shareware programs, where the adware forms an indirect ‘price’ for using the free program.
5.Spyware: Spyware refers to a software that is designed to gather data from a computer and forward it to a third party without the consent or knowledge of the computer’s owner. This includes monitoring key strokes, collecting confidential information (passwords, credit card numbers, PIN numbers, etc.), harvesting e-mail addresses or tracking browsing habits. Such activities inevitably affect network performance, slowing down the system and thereby affecting the whole business process.
6. Keyloggers: A keylogger can be used by a third-party to obtain confidential data (login details, passwords, credit card numbers, PINs, etc.) by intercepting key presses. Backdoor Trojans typically come with a built-in keylogger; and the confidential data is relayed to a remote hacker to be used to make money illegally or gain unauthorized access to a network or other company resource.
This were some types which I thought I should explain.
To protect oneself, the person should have updated virus definitions.
Virus definitions:Virus definitions (or signatures) contain a unique sequence of bytes used by an anti-virus program to identify each piece of malicious code. Signature analysis is one of the key methods used to find and remove malicious code.
