What are some ways that computer viruses spread?

Computer viruses, or malicious sections of code intended to damage a computer system, spread in several ways. True viruses are self-replicating, meaning that there is a piece of code causing them to copy and distribute themselves. By:

Posing as something useful (known as a Trojan horse) ie a download, a gift from a friend, etc. Current scam is a 'gift card' or an 'ecard' email that tries to run a malicious script when opened. Because you gave the computer the command to open the file, the virus has an easy path in. By:

Emailing itself - will search for anything fitting an email address xyz.com and then send itself there. By:

Infecting a 'clean' file without the owner's knowledge - lots of viruses can be spread this way, by people downloading files from safe sources that have been hacked by people intent on spreading viruses. By:

Using networks - if one computer on a Local Area network or wireless network is infected, this type of virus will infect every computer on that network if not blocked by a suitable firewall. By:

Using removable media - usually, disks, USB drives, external hard drives, floppies, CDs etc. are not checked by the virus scanner when they are inserted, so a virus hiding on one can get onto the computer unquestioned. Most viruses are spread by 'freaks' or people who hack computers and write viruses because they are essentially twisted people who enjoy causing damage. Some are more targeted, ie stealing information or money, or destroying particular programs. All of them have the potential to do great damage, and there are more ways to spread them than mentioned above.;

How do you know if your android phone has a virus?

You can normally tell if you have a virus because your computer may be running slower then usually. However, your computer may also be running slower then usually if your system is updating or running a anti virus scan. Another reason you may think you have a virus is because programs may "Not Be Responding" if this is happening then you may have a virus. Viruses however generally go without being detected and can run in the background without you even knowing. This is why you should do regular virus scans. Hope this has helped.

What 3 anti spy-ware programs can be wsed on a PC?

By Khalid Betani

  • Number 3: Lavasoft's Ad-Aware SE, Personal Edition

    Cost: Free

    About.com Rating: 4.5 stars out of 5

    Editor's comment: Lavasoft has been the benchmark spyware-defense tool for years. Their Ad-Aware product has won the trust of millions of users. Although it doesn't have the nifty shredding and email opt-out lists of Spybot, Ad-Aware does perform realtime protection, and it auto updates its definition lists to remain current. Up until 2006, combining Spybot and Ad-Aware was the smartest (and the cheapest) way to defend your compute against spyware. Things are different now, because Number 1 below has set the high bar even higher for 2007.

  • Number 2: Navarre Webroot Spy Sweeper

    Cost: Free to try, approximately $39 to buy

    About.com Rating: 4.5 stars out of 5

    Editor's comment: Achieving 100% detection of spyware toolbars in recent About tests, Spy Sweeper was also effective in shutting down nearly 85% of active malware processes. This would go well as a three-way combination with Spybot and Lavasoft.

  • Number 1: Macafee Virus Scan and Anti Spyware

    Cost: Approximately $39.99 for antivirus and anti-spyware combined

    About.com Rating: 4.5 stars out of 5

    Editor's comment:

  • In recent About.com tests, Macafee managed to detect 100% of all spyware infection, and it also shut down nearly 99% of spyware processes running in memory. While you cannot purchase Macafee anti-spyware without also purchasing their antivirus, the bundle is absolutely worth it at $39.99. If you are willing to spend money on your spyware and virus defense, then Macafee and Web Root are the two choices we recommend to everyone. If you are looking to save yourself a few dollars, then Lavasoft/Defender/Spybot can make for a good no-cost combination defense.

What is the origin of the Internet and how does it work?

The Internet is a worldwide network of interconnected computers that allows users to access and transfer information remotely. The information viewed on the Internet is actually not on the Internet at all, but rather on other computers, and viewed via the Internet. The most popular service accessed through the Internet is the World Wide Web (WWW). The Web and the Net are often considered to be synonymous but actually represent two different things. Whereas the Internet is the means for accessing information, the Web is composed of the visual display of the information being accessed.
