In this article some of the simplest methods to identify whether a system has been infected by a malware have been discussed. Additionally, it also provide some pointers as to how to prevent such intrusion signatures.
As the usage Internet increases, so does the chances of personal or business information being accessed by unknown third parties. In most cases the information is accessed without the knowledge of the user. In other words, the user is unaware that his or her system has been infected by a malware. Such intrusion signatures can often disguise themselves as harmless looking programs, making the identification of the malware all the more difficult.
Most of the clients who contact Norton support UK are mostly unaware as to how the intrusion signature entered the system. Additionally, they are also often unable to identify the location of the malware on the system. Similarly most users calling up on contact AVG UK service mention that they are unable to identify the malware, in spite of having installed an Antivirus program.
Hence, it is essential to understand the behaviour of a system on being affected by a virus and some of the pointers are as follows:
- Memory usage has increased: Check if the memory usage of the CPU has increased in spite of no programs running in the background. This is a clear indication of a malware affecting the system.
- Slow booting of computer: If the system takes a long time to boot, then check if there are any malicious software in the computer. One of the end results of malware infection is that the overall performance of the system will be adversely affected.
- Check for system generated messaged: If one is getting the ‘Solve PC issues’ message on one’s system, then check if the firewall of the Antivirus installed have been turned on. If the firewall has been turned off, then chances are there that a malware could have entered the system. Turn on the firewall and then run a full system scan to identify the malware and remove it.
Thus, the most common indication of a system being affected by a malware is that the computer will become slow and behave in an erratic manner. In such a scenario, the ideal step would be to run a full system scan, identify the malware and then remove it.
