Malware is a software application that was created with the purpose of affecting normal computer operation. The term actually originates from a combination of the words “malicious” and “software”. When the PC security has been bridged, the Malware will access computer resources and affect performance as well as doing other forms of damage. This malicious threat is aggressive and extremely intrusive; and may be tricky to detect. It can take on various forms such as Trojans, Viruses, Worms, Spyware, Root-kits, Botnets and Adware.
Malware must not be confused with defective software. Both of these are able to have harmful effects on computer systems and there is support that infected parties can call. Defective software is legitimate software which has code that can affect your PC but is much less harmful than Malware. On the other hand Malware is not legitimate software can be extremely harsh on computer systems.
Prior to the explosive growth on the internet, Malware was spread by hiding in the boot sectors of floppy drives. The very first occurrence of Malware was recorded in 1988 when it appeared as an Internet Worm and attacked VAX BSD and SUN Operating systems. It found defects in the network server software and then started running an independent process.
Most Malware is targeted against the Windows operating system and started this vendetta in the early 1990s as the operating system gained popularity. Macros which are an essential component of Windows were used as the platform for developing Malware. Very few variants, such as Lionware and Mare D, are directed against the Linux and Unix operating systems. Fortunately vendors of computer security software are constantly honing their products to deal with new Malware threats as they are released online.
Malware is responsible for performing various malicious acts which interfere with normal computer usage. They adversely affect computer performance often by spamming your email inbox with advertising emails. The security of your personal data is compromised as key strokes are recorded, opening the door for password theft and identity hijacking. Your online experience is also affected when you get redirected to illegal advertising sites. Sometimes your computer may be hijacked and unknowingly it may even used as a sever to relay material which is offensive. As new Malware are developed they also come with new methods of performing their deeds of destruction. Always seek professional assistance when an infection has been detected.
There are a few main types of Malware, with sub-variants found of each type. Some of them are able to self-replicate like Viruses which are able to spread from PC to PC. Then there Wabbits which are like viruses but do not spread to other computers. They perform their destruction on the host PC. Worms also operate like viruses; accept that they are not inserted into files or programs.
Applications such as Spyware and Adware are often more of an annoyance. These types of threats usually display adverts in the form of pop-ups. Adware gets downloaded on your PC and displays adverts. Spyware also displays adverts by analyzing your browsing habits to establish which types of adverts are the most applicable.
Keyloggers are Malware which are able to convey personal and sensitive information back to their creators. These applications record all keystrokes and are able in that manner to transmit information about IDs and passwords. Trojans on the other hand attempts to corrupt all sensitive information stored in your PC. Then there are Exploits which attack security systems.
Rootkits are one of the most difficult applications to detect when they are able to bridge your computer system security. As a disguise Rootkits generally take on the form of a core or vital system process. It is essential to get professional help when combating a Rootkit infestation.
Dialers are Malware which uses an attached modem to dial phone numbers, while Backdoors are able to provide hackers access to your system by making network connections available. URL injectors redirect individuals to other unrelated sites when a specific site link is clicked.
Although there are many types of Malware with different modes of malicious attacks on computer systems, there are adequate recourses available for combating them successfully. When ever there is doubt concerning which solutions to use, the help of a professional is always close at hand.
