Viruses can damage a computer and, if not removed, cause all types of software problems. Worms and viruses get onto your computer when you are viewing, installing, or downloading things from the Internet. Some viruses cause technical problems, while others can hijack the computer and remotely send and receive all kinds of personal information. This is one way that hackers can obtain information and passwords, which leads to identify theft. The best way to prevent viruses on your computer is with a reputable antivirus software. Also be sure not to open any messages or download things from unknown sources.
