The Importance of AntiVirus Software

One of the most common reasons for failures or problems in computers is the lack of antivirus software. It is an issue which often overlooked and has drastic consequences for the unfortunate computer owner.

These days there are so many different types of virus which are usually hidden and can do a number of things, as it relates to the health of the computer.












Virus can be spread between computers, transferred via email and even occurred by USB drives.

There are different type of virus that are opened across the internet that users should be aware of. Certain types are:
1. Worms: these are programs which copy themselves to other computers on a network. Thy tend to slow things down as they consume more and more bandwidth or computer resources.
2. Trojans: performs functions(sometimes malevolent) on the computer without the awareness of the user.
3. Malware: technically this is not classed as a virus but it is a software used to spy on computer user's activities and collect personal information.

Now here is where antivirus software is required.

The Antivirus software acts like a "policeman". It protects the computer from incoming threats, seeks out, destroy and warns of possible threats to the system. But in doing this it has to be daily up dated with antivirus database definitions to neutralize the latest threats to provide constant protection.

To me not having antivirus on a computer is like inviting a criminal into your home or having uninvited guest. They will only cause havoc or steal from your house. The internet have many  avenues for virus attacks and there are thousands of threats.

There are various free antivirus software packages that are available on the internet and can be easily installed in your convenience.AVG, AVAST, Norton, McAfee  and the lists goes on.
Don't underestimate antivirus software, protect your computer.
