From the simple worm that imposes a search engine (and its ads) on your web browsers to the terrible Cascade which in the 80s was able to completely destroy the OS of the best computers of the moment.
There are thousands of viruses whose levels of attack and consequences are classified by danger index.
They impose themselves while browsing the web, hide in certain programs and act sneakily.
Antiviruses are unable to stop everything
Although they are powerful and essential, antivirus programs are unable to stop everything,
Malware, scareware, worms and viruses their actions:
- Analyze your files and identify your codes or bank statements
- Stealing your address book and sending emails in your name…
- paralize your computer, freeze your mouse or drive it crazy.
- Shut down or restart your machine
Permanently and methodically remove viruses
Scan to remove unwanted programs that have accumulated over time from your PC.
Then I install and run a small software to clean up your machine, i.e. delete temporary files, shortcuts that are no longer used, as well as some errors in the Windows registry. An antivirus scan is also required to make sure that your PC is not infected. When the optimization is complete, your PC runs almost as if it were freshly installed.
Malware, scareware and other scareers
Malware, or malicious software, is a program introduced into a computer system and causes a whole series of infections to spread through it.
Malware is divided into different categories, including viruses, worms, Trojans, and other threats, including scareware .
In order to protect against this kind of nefarious invasion, it is necessary to define what scareware is and how it enters the system. We will then see what to do in case of infection.
Nature, origin and consequence of scareware.
Scareware presents itself as anti-spyware and its purpose is to generate money. It takes the form of a false alert that the computer is infected. Often, the wallpaper is changed or pop-up icons appear and push the user to pay in order to protect their computer and preserve all their data.
If you click, the scareware will detect imaginary threats and give the illusion of cleaning them. To do this, the malware supposedly scans the computer in record time (actually unfeasible).
A false alarm can appear very repetitively in order to scare the user as much as possible, while giving the illusion of being a completely serious anti-spyware.
Scareware can install when downloading or browsing questionable sites.
Activating scareware can trigger a malicious download that can in turn infect the system.
How to get rid of scareware or other malware.
First of all, it is essential to install an antivirus and a firewall on a computer.
The second piece of advice to follow is to never pay anything.
When malware is detected, it may be useful to reinstall the antivirus that may have been disabled. This way, he will eventually be able to eliminate the intruder. Disabling System Restore is necessary because antivirus software does not scan certain files hidden by the system.
If that doesn’t work, there are premium tools available online that can also eliminate the malware.
The ultimate solution to get rid of malware is to be able to determine its type. Depending on this, online tutorials serve as a guide in the procedure to follow.
Software can also be used to eliminate recalcitrant malware.
If all these solutions remain ineffective, all that remains is to reformat the hard drive and reinstall the operating system and its various applications, after destroying all the sensitive files on the hard drive.
In short, vigilance is required when it comes to the use of the internet, as malware has rapidly proliferated with the democratization of the web. But beyond this preventive notion (watching over downloads, sites visited and various actions on non-secure sites) which is unfortunately not sufficient, the restorative notions described can be very useful.
