What are the symptoms of a computer virus?
If your computer is running slower than usual, crashing more often, or displaying other unusual behavior, it may be infected with a virus. More serious signs that your computer has a virus include new toolbars appearing in your web browser, changes to your homepage, or unusual pop-up ads.
Although many of these symptoms can be caused by other problems, such as a buggy software program or a hardware problem, it’s always best to run a virus scan to rule out the possibility of infection.
There are two main types of computer viruses: file-infecting viruses and boot-record viruses. File-infecting viruses attach themselves to executable files, which are programs that can be run on a computer. When you run an infected program, the virus copies itself into memory and then searches for other programs to infect.
Boot-record viruses, on the other hand, infect the boot sector of a hard drive, which is the part of the drive that contains the information needed to start up the computer. These types of viruses are particularly dangerous because they can prevent a computer from starting up at all.
In addition to slowing down your computer and causing other strange behavior, viruses can also damage your files or even delete them completely. And if a virus gets into your email program, it can send itself out to everyone in your address book, infecting their computers as well.
Fortunately, there are a number of steps you can take to protect your computer from viruses, including installing antivirus software and keeping it up to date. Antivirus software works by scanning your computer’s files and memory for signs of infection and then removing any viruses it finds.
It’s also important to be careful about what you download and open. Don’t open email attachments from people you don’t know, and be cautious about downloading programs from the Internet. Only download programs from websites that you trust, and be sure to scan them for viruses before opening them.
By taking these steps, you can help keep your computer safe from viruses.
