Equine herpes virus (EHV) is a highly infectious strain of the herpes virus that can cause respiratory distress, neurological symptoms, and abortions in mares. EHV-1 and EHV-4 are the most concerning strains. Outbreaks can occur when a carrier horse sheds the virus, and vaccination does not completely protect against infection. Quarantine, disinfection, and isolation are […]
Norovirus, also known as Norwalk virus, causes gastroenteritis and is highly contagious. It is estimated to cause 50% of intestinal ailments worldwide and is often contracted through contaminated surfaces or food. Treatment focuses on fluid replacement and rest. Outbreaks often occur in crowded settings like schools, prisons, and cruise ships. Norwalk virus or norovirus is […]
It’s hard to tell the difference between a virus and bacterial infection as they have similar symptoms. A high fever may indicate a bacterial infection, and symptoms worsening after a few days may also suggest a bacterial infection. It’s best to see a doctor for tests to determine the cause of the illness. It can […]
Smallpox, caused by the variola virus, is a highly invasive and potentially fatal disease that was eradicated in the 1980s. Due to the threat of biological warfare, research is being conducted to better understand the virus and potential treatment options. Symptoms include flu-like signs and a telltale rash that can be fatal. Treatment focuses on […]
Any virus can cause hives in some individuals, with roseola being a common example. Hives related to a viral infection usually clear up on their own without treatment, but any persistent symptoms should be examined by a doctor to rule out complications. Hives can be caused by an oversensitive immune response due to allergens or […]
H1N1 is a common cause of influenza in humans, with some strains being endemic to pigs or birds. The 1918 Spanish flu pandemic killed millions due to a cytokine storm, with young adults more at risk. In 2009, a new H1N1 outbreak was declared a pandemic, with symptoms similar to the flu. The virus had […]
Hendra virus, believed to come from a type of bat, can infect horses and humans through contaminated bodily fluids. There is no current treatment, but researchers are investigating preventative measures, including a vaccine and good hygiene practices. Hendra virus was originally discovered when a small group of horses and people in Australia developed an unusual […]
MRSA is a type of antibiotic-resistant bacterium that can cause infections in different parts of the body. It is more common in people with weakened immune systems and those who work in healthcare settings. Symptoms can vary, and if caught early, the virus can usually be contained. The MRSA virus is not actually a virus; […]
Rootkits and viruses are both types of malware, but serve different purposes. A rootkit allows unauthorized access or hides other malware, while a virus is designed to achieve a specific goal. Rootkits are harder to detect and remove, often requiring a complete system wipe. It’s important to avoid all types of malware. While a rootkit […]
Keeping an up-to-date antivirus program is crucial for preventing and removing spyware and viruses. Removing them can be difficult, but starting the computer in safe mode or from a disk can help. Reformatting the drive is extreme, but effective. Safe computer habits, such as avoiding suspicious links and emails, can also prevent infections. There are […]
Viruses are tiny particles that require hosts to survive and reproduce. They cause disease and are notoriously difficult to treat due to their ability to mutate rapidly. Antiviral drugs focus on attacking the proteins of the virus, but the best cure is a vaccine. A virus is a particle of infectious material. Viruses are incredibly […]
A stealth virus hides itself after infecting a computer and is difficult to detect during a virus scan. It can spread through malicious programs, email attachments, and websites. The virus creates a copy of the original system image to avoid detection and can reinstall itself after being eliminated. A stealth virus is a type of […]
As of 2010, there were no CPU viruses in circulation, but hackers are working on releasing them. Antivirus software is not designed to prevent or eliminate them. If infected, it may be expensive to replace damaged hardware. Prevention includes buying good antivirus software and avoiding downloading from unknown sources. If infected, seek help from a […]
Antivirus applications are commonly used to protect against viruses on the internet. Macro viruses require user action and can be a nuisance. Trusted macros are the safest and can be created by the user or IT department. It’s best to avoid accepting files with macros and to research before creating them. Disabling macros by default […]
Polymorphic viruses mutate when they replicate, making them difficult to detect with ordinary antivirus software. They require more complex algorithms to identify distinctive patterns. The first known polymorphic virus was developed in 1990. Polymorphic viruses can operate in different ways, making them difficult to block. They can remain undetected even with anti-virus software in place, […]
A computer virus scan identifies and removes threats from a computer’s hard drive, protecting it from damage. Both paid and free virus scanning software is available, with some free versions being just as effective as paid ones. It’s important to research and read reviews before downloading any virus scanning program. A computer virus scan is […]
Malware viruses are unwanted or malicious software that can harm a computer or network. They can be viruses, worms, Trojan horses, spyware, or other forms of unwanted software. Malware can serve various purposes, from pranks to financial gain. Trojan horse viruses are particularly dangerous, as they can erase hard drives or steal confidential information. Keystroke […]
A computer virus hoax is a fake message warning about a non-existent virus, often received in an email. It can instruct users to delete legitimate files and may claim to be from authoritative sources. True computer viruses can cause serious problems, such as stealing personal information. Virus hoaxes are usually harmless, but some can cause […]
The hybrid virus is a difficult type of virus to control as it combines elements of other viruses, infects both system sectors and program files, and can launch a two-pronged attack on the system. It is extremely difficult to remove and prevention is key through caution when opening suspicious attachments and keeping anti-virus software up-to-date. […]
Herpes simplex virus (HSV) includes two viruses that cause genital herpes or cold sores. Both types are transmitted through skin-to-skin contact and are incurable, but medication can reduce outbreaks. HSV can be transmitted even when there are no symptoms, and precautions should be taken to prevent transmission. A vaccine is being developed to prevent infection. […]
