Protect from virus // Before attack

Protecting computer before the virus attack is the most intelligent move. Most people just stay and they will panic if there is a virus and there will be less chance of recover. We can minimise the damage and less recover time if we follow precautions.

We are going to eat an apple day by day to keep doctor away.

1) Install antivirus 

This is the most important step. This type of software work in real time and they like to catch virus. In future posts I will teach you how to remove virus by yourself . Using antivirus software it will minimize our effort and time.

Don't buy antivirus software. There are many and best free software.

Microsoft Security Essential

Avira

Comodo

Avast

Bitdefender

2) update antivirus

Most people don't like about antivirus because it popup a message like "your antivirus is may not working properly. Please update''. some people don't use antivirus if it ask update frequently. Think you installed new antivirus software last month and it is not updated. Some crazy (best) programmer writes a new virus with new concept in last week. Our antivirus can identify virus until last month because it has one month old knowledge about viruses. I mentioned that new virus is made with new concept. Whatever your antivirus (world's best or paid one) it can't identify the virus. Antivirus making people are always find about new virus and they provide update. With the new update antivirus can detect new threats.

3) Install a firewall

This is another big post. I will write it soon.

4) Update your browser and operating system.

Many internet browsers default setting is ''update automatically ''. If not update them.
If you are using pirated copy of operating system there will be small problems with updating. However operating system updates provide many security patches.

Use Linux. It is free. No virus problems. It is fast. It is simple.
