How to Protect The Computer from Viruses

There are some viruses that create different problems in computer system. Some viruses may detect some special information like passwords, or any sensitive data. They may send this information to some other user on a network. For example, a virus program may read the "Pin Code" of credit card, entered by a user and then send this information to another user. Some viruses may make resources unavailable to the users. For example, a virus after copying itself on all computers on a network, may affect the communication activity on the network. The network may become unavailable for the users.

You can make safe your computer from getting infected by a virus by using following 7 ways:
