Are you finding it harder and harder to protect yourself from malicious attacks from the internet?
For virus prevention, you should first start with how to identify them. We will start with sorting them in basic categories.
Viruses – they attach themselves to any file so that when you start the program, you activate the virus. These viruses are usually sent through email or downloaded files from the internet.
Worms – worms are just like what they sound. They keep multiplying and using up all the resources from the computer till the computer comes to a complete stop. These usually are spread through P2P programs and email. They can also be spread over your local network.
Trojans (a.k.a Spyware) – Trojans are the worst. They are used to steal information from the user. They are installed and used without permission and usually have some type of key logger to record what you are typing and send it back to the source so that they can collect credit card numbers and username/password to accounts. These are generally the hardest to find because they usually consists of multiple files.
The best way to protect from and prevent infections is to run the best antivirus/spyware software around. The number one common reason people get infected is not that they accidently download it but, that they do not keep track if their antivirus is installed and updated properly.
Just because you see in the bottom corner that your antivirus is running, does not mean its doing its job. Every day you should check to make sure that your antivirus is updating so that you are protected against the most recent infections. By doing that even if you download a virus the antivirus will scan the file and catch it before it gets too late.
If you do not have an antivirus program installed, I recommend installing one as soon as possible.
One of the best currently out right now is Computer Associates E-Trust Integrated Threat Manager and Antivirus. The program isn’t free, but is a bargain compared to the cost of downtime and an infection.
