In this article the common malicious programs or malwares have been discussed. Additionally, in this article the effect of a malware infecting a system have also been elaborated upon.


If the Internet makes daily communication simpler, it is also a challenge to ensure the safety and security of the information being transferred via the Internet. In many instances, end users storing personal or business data on virtual drives have been shocked to discover that the drive has been hacked into. The same is applicable even for the hard disk installed in the computer itself. Additionally, with the advent of mobile devices the chances of being attacked by malicious software too have increased manifold. Thus, the question arises how to ensure the security of the information stored in a computer or even a virtual drive?

According to AVG support UK technicians sometimes systems can get infected by malicious software if proper precautionary measures are not followed by the end user. It is essential to understand that new and vicious intrusion signatures develop as the Internet technology itself advances. In such a scenario it is essential that the end user too must protect his or her system with the latest Antivirus. Most clients who contact Norton antivirus UK are unaware that they had inadvertently allowed a virus to enter a system by opening a mail from an unreliable source or by clicking on a link that contained the virus signature.

Thus, it is essential to understand the basic nature of the malicious programs and the two most common malwares are as follows:

  • Virus: These are self-replicating programs that require a host file. Once the host file is opened by the end user the virus gets activated and can affect all programs in the entire system. If the system is connected through a home network to other systems, then consequently all systems will be affected by the virus. Hence, to prevent such intrusion signature never open a file from an unreliable source, download data from unknown websites and always have the latest Antivirus running on the system.
  • Trojan: These are not virus themselves but the Trojan malware weakens the firewall of a system making it easier for viruses to enter a system. These malwares spread only through user interface.

Thus, to protect one’s system from being affected by an intrusion signature ensure that all safety measures are followed.
