And that in most cases they are used with a malicious end. Here we will see how to remove viruses.

It is not always easy to know if pc is compromised or not, because nowadays cyber criminals make great efforts to hide the code and hide what their programs are doing on the infected computer. Therefore it is very difficult to provide a list of symptoms characteristic of an infected pc. And that’s because the same symptoms can also be caused by hardware incompatibilities or system instability, however, here are just a few examples that may suggest that your PC has been compromised:

  • You may receive the error “Internet Explorer could not display the page” when trying to access certain websites.
  • Your web browser (e.g., Microsoft Internet Explorer, Mozilla Firefox, Google Chrome) becomes blocked, hangs, or unresponsive.
  • The default home page of your web browser is changed for no reason.
  • You are redirected to web pages other than the one you intended to visit.
  • You receive numerous web browser pop-ups (popups)
  • Strange or unexpected toolbars appear at the top of your web browser

  • There are new icons on your desktop that you don’t recognize
  • Your computer restarts on its own (but not a restart caused by Windows updates)
  • You will see unusual error messages (for example, messages that indicate that corrupted folders or files are missing)
  • You cannot access Control Panel, Task Manager, Registry Editor, or Command Prompt.

Within the malware is included viruses, ransomware, worms, Trojans, rootkits, keyloggers, dialers, spyware, adware,rogue security software and other malicious programs; most active malware threats are usually worms or Trojans rather than viruses.

Below you can find a brief description of the types of malware that can be found the most:

  • Trojans
    Trojan is a type of malware that pretends to be something useful and fun while causing damage or data theft. Trojans often silently download other malware (e.g. spyware, adware, ransomware) onto an infected device as well.
  • worm
    A computer worm is a type of Trojan capable of spreading or replicating from one system to another. You can do this in several ways. Unlike viruses, worms do not need a host file to hook up. After arriving and running on a target system, it may perform a number of malicious tasks, such as removing other malware, copying itself to devices physically connected to the affected system, deleting files, and consuming bandwidth.
  • spyware
    Spyware is another type of malware with the peculiarity that it is very difficult to detect. It collects information about your browsing habits, browsing history or personal information (such as credit card numbers) and often uses the Internet to transmit this information to third parties without your knowledge. Keyloggers are a type of spyware that monitors your keystrokes.
  • ransomware
    Ransomware is a threat that prevents users from accessing their system or personal files and demands a ransom payment to regain access to them. In many cases, even if you get to pay the ransom, your files/access are not returned to you.
  • Rootkits
    The term “rootkit” comes from the “root kit”, a package that grants the highest privileges on the system. It is used to describe software that allows the stealth presence of unauthorized functionalities in the system. Rootkits modify and intercept typical modules of the environment (operating system).
  • adware
    It is usually a standalone program that displays advertisements to the end user in a variety of ways: within the program itself, or via pop-ups, slither ads, browser pop-ups, embedded ads, or altered website content. The revenue generated by the ads is the way in which the program to which the adware is attached is paid, which means that the end user receives their desired tool or service “for free”.
