What is a worm?
A worm is a type of malware that copies itself and infects computers. It can spread through email attachments, network shares, and drive-by downloads. A worm can also take advantage of security vulnerabilities to infect a system.
Worms are different from viruses in that they don’t need to attach themselves to files or programs. Once a worm is on a computer, it can spread to other computers on the same network without any user intervention.
Worms can cause a lot of damage to a computer network. They can clog up network traffic, making it difficult for users to access resources. They can also delete files and damage programs.
Worms are a serious security threat and can be very difficult to remove from a system. If you think your computer may be infected with a worm, you should run a scan with a security program..Click for source
How can I tell if my computer has a virus?
There are a few things you can look for if you’re wondering if your computer might have a virus. One is changes to your computer that you didn’t make yourself. Maybe your home page on your web browser has been changed, or there are new icons on your desktop that you don’t remember putting there. If you notice any changes like this, it’s possible your computer has been infected with a virus.
Another thing to look for is strange or unexpected behavior from your computer. If it’s running slowly or crashing more than usual, that could be a sign of a virus. You might also see error messages that you don’t understand, or popup windows with ads that seem suspicious.
If you’re worried that your computer might have a virus, the best thing to do is run a virus scan. Most antivirus software will have this feature, and it will go through your computer’s files to look for anything that looks like a virus. If the scan comes up clean, you’re probably in the clear. But if it finds something, you can take steps to remove the virus and get your computer back to normal.
