Personal Computer Security

| | 0 Comments

A personal computer can hold a lot of information about an individual. This information must not reach unauthorized persons. Under normal circumstances, he would remain private. But the Internet offers unscrupulous people new ways to retrieve information from other systems without their knowledge of data theft.

When a person opens an infected email (or more precisely a program is run from the email), a virus is transmitted that can leave your computer open to attack. This type of viral infection also occurs on websites. Every time you download a program to run on your computer, it is possible that it installs a program that monitors what you do on your computer and compromises your security.

Warez is a term that refers to pirated software. People tend to download this software because it is offered for free on the Internet, while the software is expensive if it is legally purchased. Generally, spyware is associated with the software, which, when executed, allows remote access to the personal information of the computer.

Trojans are the most common malware (referring to programs that seem to be well established, but also install a virus or hidden spyware). Once the system is infected, the hacker manages to extract important data such as bank account details, bank balances, passwords, etc., in order to withdraw money. In general, this is the real reason for hacking, although the hacker can also use other personal information, such as pictures of the person or a personal correspondence. Identity theft would have increased in recent years.

So, how do you prevent piracy? There are several anti-spyware programs available on the market, such as Norton, Kaspersky, AVG, and so on. Another way is to install a firewall, which prevents some external attacks on computers connected to the Internet. A combination of two or more antispyware methods would be of considerable help.

Since there is a good chance of failure in preventing security attacks, it is good to know the symptoms as well. The person may notice unusual behavior on the part of a PC, for example, ads that appear without clicking, or applications that close spontaneously. The Internet connection can also often become slower. All of these are potential indicators of infection and it is warranted to perform a virus check to prevent further loss of data or files.
