What are the symptoms of a virus?

Viruses are tiny infectious agents that can cause a wide variety of symptoms. Most viruses cause mild to moderate symptoms, such as a fever or diarrhea, but some viruses can cause severe or even life-threatening illness, such as Ebola or Zika.

The symptoms caused by a virus depend on many factors, including the type of virus, the individual’s age and health, and the particular strain of virus. For example, the common cold, which is caused by a virus, typically causes mild symptoms, such as a runny nose, sore throat, and cough. In contrast, influenza, another virus, can cause more severe symptoms, such as high fever, muscle aches, and fatigue.

While some viruses cause only a single illness, such as the flu, others, like the human immunodeficiency virus (HIV), can cause a lifetime of infections and illnesses. HIV attacks the body’s immune system, which makes the person infected susceptible to other infections and illnesses, such as pneumonia, skin infections, and cancer.

There is no cure for viruses, and most viruses can only be treated with symptom relief. However, there are a few vaccines available that can help prevent certain viruses, such as influenza, from causing illness..Full Article

What is a rootkit?

A rootkit is a software program that allows an attacker to gain, or maintain, access to a computer system without being detected. It is a collection of tools that are used to concealed any traces of an attacker’s presence on a system and provide an attacker with a way to remotely control the system. A rootkit can be used to hidden files, process, Registry keys, and network connections to maintain control over the system and to allow an attacker to remotely execute commands on the system.

Rootkits are usually installed after an attacker has gained access to a system using another method, such as a Trojan horse program or a buffer overflow exploit. Once the attacker has gained access to the system, the rootkit is used to conceal the attacker’s presence and activity from the system’s administrator. The attacker can then use the system as a launching point for attacks on other systems or to collect sensitive information from the system.

Most rootkits are designed to work on a specific operating system and can be very difficult to detect and remove once they are installed. Some rootkits can reprogram the system’s BIOS or Master Boot Record to make it difficult to detect and remove the rootkit. In some cases, a rootkit can be used to create a “backdoor” into a system that allows an attacker to bypass security protections and gain access to the system.

Rootkits are a serious security threat and can be very difficult to detect and remove. If you suspect that your system may have a rootkit installed, it is important to scan your system with an antivirus program and remove any malware that is detected. It is also important to keep your system and software up-to-date with the latest security patches to help prevent attackers from exploiting vulnerabilities to install rootkits.
