Any doubt you need Anti-virus software protection?
At this very moment, over 200 active viruses are roaming and spreading throughout the Internet.
Anti-virus software protects your computer from viruses that can destroy your data, slow your computer’s performance, cause a crash, or even allow spammers to send email through your account.
You get a computer virus via email, downloads, infected disks or from hacking. Anti-virus programs works by scanning your computer and your incoming email for viruses, including worms and Trojan horses, and then deleting them. Such virus scan software programs may also detect and remove adware, spyware, and other forms of malware. Antispam software is also included in some programs.
The term computer virus is sometimes used as a catch-all phrase to include all types of malware. Malware includes computer viruses, worms, Trojan horse viruses, most rootkits, spyware, dishonest adware, crimeware and other malicious and unwanted software including true viruses.
Viruses are sometimes confused with computer worms and Trojan horses, which are technically different. A worm can exploit security vulnerabilities to spread itself to other computers without needing to be transferred as part of a host, and a Trojan horse is a program that appears harmless but has a hidden agenda. Worms, and Trojans, like viruses, may cause harm to either a computer system’s hosted data, functional performance, or networking throughput, when they are executed. Some viruses and other malware have symptoms noticeable to the computer user, but many are surreptitious.
Most personal computers are now connected to the Internet and to local area networks, facilitating the spread of malicious code. The web, email, instant messaging and file sharing all allow viruses to spread.
The best way to protect your computer from viruses is to resist opening email attachments and downloads from unknown and unreliable sources and get a reliable defense program that scans and updates regularly.
