Protect Yourself From Hackers

hackerYour PC has many “ports” which are vulnerable to attack from a hacker. These ports are used to communicate internally with your monitor or printer or externally to the internet. For example, Port 25 is used for receiving incoming email and Port 80 is used to connect to the internet.

In addition you have a unique IP number which is assigned to your computer by your Internet Service Provide which is required for you to use the internet. This is how you send and receive information. It also serves as your computer’s “address”. The IP number looks like this – 106.185.21.243.

If you have a broadband or DSL connection your IP address rarely changes which makes your computer more vulnerable. Another issue is that with broadband connection you are likely to be on line for longer periods of time giving hackers more opportunity to attack you.

Hackers use “port scanning” software to hunt for for vulnerable computers with open ports using your computer’s IP address. They will then send malicious programs through these open ports onto your computer.

Another common way that hackers use to gain control of your computers is by sending out trojan viruses disguised as email attachments. Hackers typically send out these messages to 1000s of users with enticing headings and an attachment which they are hoping you will open. When the attachment is opened the virus loads itself onto your computer and allows the hacker to control your computer.

Hackers also bundle Trojan viruses into free downloads like screensavers which are commonly installed on home user’s machines. Illegal P2P networks also circulated large numbers of infected files. Here are some steps you can take:
1) Make sure you are receiving the latest Window’s updates.
2) Have a good firewall installed.
3) Install anti spyware removal software and keep the program up to date. Run a scan at least once a week or after being on line for a long period of time.
4) Install an anti virus program and keep the virus definitions up to date. Carry out a virus scan a least once a week.
