Virus mostly spread through portable devices such as Flash Disks, Floppy disks, via computer networks, Emails and online downloads. In this tutorial I will show you some useful tips to prevent your computer from Viruses.

  • Antivirus: Install an Antivirus program. There are many Antivirus programs available on the Internet. Both paid and free. You must have an antivirus program installed on your computer. Every month you should upgrade Antivirus program. 
  • Email: Never Click on undefined source E-Mail attachments. Always be careful when you check your E-mails.
  • Instant Messaging: You might use instant messiging services such as G-mail, MSN, Yahoo and AIM. May be your friend send you an attachment. You will accept it directly instead of thinking what he/she’s sending. If you see your friend sent you an attachment you must ask your friend that you really sent this attachment.
