In our TOP 10 internet threats, we show you the methods hackers use to access your data and how you can protect yourself against them with hardware and software-based solutions.

Viruses, Trojans & Worms
Although they have been around for decades, viruses, worms, and Trojans still represent the network’s greatest computer systems threats. And the amount of malware in circulation is increasing every day: around 350,000 new species appear on the network every day. Although the terms viruses and worms are often used interchangeably, they are different types of malware.
The computer virus is the oldest malware. As early as 1974, the first computer virus, “Rabbit,” was developed. Viruses are programs that can replicate themselves in order to spread from computer to computer in this way. Then steal or delete data on the affected systems. Most viruses are hidden in a program. As soon as the user runs this program, the virus spreads. The user spreads viruses by unintentionally forwarding the infected files, e.g., by email or on data carriers such as USB sticks.
Worms are similar to computer viruses, but they do not depend on the “assistance” of the user and spread independently via networks and data carriers by mercilessly exploiting security gaps.
In contrast to worms, Trojans do not reproduce on their own. They often pose as legitimate software and then nestle on the computer unnoticed. Trojans allow hackers direct access to the computer, so they can manipulate, steal, or delete data.
4) Web-based malware
The user catches web-based malware in particular when using outdated web browsers. Often it is browser plugins that allow this malware to install itself on the computer. Many millions of Internet addresses are infect with web-based malware.
Who does not know it: the email inbox is full of unwanted (advertising) messages. These emails are not only annoying; they can also be dangerous because it is not always just advertising emails. These messages are often based on an infected file or a link to malware. The emails are sometimes so well camouflaged that you have to look very carefully. For example, there are fake bills in circulation.
Spyware (spying software) spies on user behaviour and data without the owner’s knowledge and consent. They serve to analyze the surfing behaviour of the user; the data obtained are used commercially. It is not uncommon for companies to develop spyware themselves to learn more about their customers.
Anyone who catches adware (advertising software) will be shown unwanted advertising. Adware is often built into free programs and is difficult to detect. The advertisement can also reach the PC via infected websites. Usually, adware does not harm your computer, but it is very annoying.
Phishing describes hackers’ attempts to access sensitive user data via fake websites, emails, or instant messengers. In such emails, the user is ask to visit fake websites or to disclose secret access data. Well-known, trustworthy websites are imitate and the users’ good faith is shamelessly exploited. Sometimes the fake websites look so real that you can hardly make out any differences from the original. As a rule, hackers target account or company-critical data when phishing. In the worst case, the bank account can looted in this way.
9) Bot networks
Botnets are a whole group of PCs that have been infected with malware and combined to form a large network. These botnets often extend over several thousand computers. The malware used is called robot programs (bots). They are remotely controlled by hackers and used for criminal offenses. For example, they automatically send massive amounts of spam and spy out data. All of this happens in the background without the user being able to suspect that his computer has become part of a criminal structure. In addition to computers, mobile devices such as smartphones or tablets can also be affected by bots.
10) Denial of service attacks
Constant availability of servers, applications, and data is essential for companies. It is precisely this high commodity that the hackers target in a Denial-of-Service (DoS) attack. They try to attack websites and servers to make important data or entire systems inaccessible to the owner. This is usually achieved through targeted attacks on servers to overload them completely. To this end, huge numbers of requests are directed to the server.
You can use Antivirus software to protect your PC from such a virus. there is much software available in the market. Windows users can get Microsoft Security Essential for FREE. Avast is another FREE software in the market.
