The digital certificate and an electronic file containing data of a person or institution, used to verify your identity. This file may be stored in a computer or other media, as a token or smart card.

Examples similar to a digital certificate are the CNPJ, RG, CPF and driver’s license of a person. Each contains a set of information that identifies the institution or person and authority (for these examples, public organizations) that guarantees its validity.

Some of the key information found in a digital certificate are:

• data that identifies the owner (name, identification number, status, etc.);
• name of the Certification Authority (CA) that issued the certificate;

What is Malware?

The term malware is actually short for malicious software. Malware is software whose sole purpose is to infiltrate and damage computer systems without the owner being aware of its existence. Malware has several specific types of software included under its umbrella name – computer viruses, rootkits, spyware, adware, worms and trojan horses are just a few.

Malware can be confused on occasion with defective software. When a piece of legitimate software programming does not work properly, this is due to possibly harmful bugs and should not be considered malware. This is, however, not to say that malware cannot be the culprit of a dysfunctional computer, however, detection by appropriate software is always recommended.

A computer virus is a nasty little program that can replicate itself and infect your computer without you ever knowing it was there.

Computer viruses and other forms of malware are probably the biggest source of problems for computer users around the world, expecially those using Windows operating systems.

Virus can spread themselves between computers very easily, via disks, USB sticks, local networks and across the internet.

I’ve met many people, both in the real world and via my online socialising, that have been fooled by this misconception that a proxy server can provide you with some privacy.  Although I say it is a mistake, there is some small element of truth, perhaps just enough to be dangerous.

For let’s remember what a proxy server is and then examine the real attacks on your privacy.   A proxy server sits in between you and the web sites you visit, it does protect these web sites from detecting your location and IP address but only when they are configured correctly.

The proxy contains every single request you make online, unless it’s logs are purged it contains a
