The presence of this virus is often considered insignificant for some people, even if its effects and damage are terrible. For this reason, specific measures are needed to overcome or at least minimize the impact.
The most important thing in preventing the Trojan virus from entering the computer version of teknobaik.com is to install an antivirus. Try to keep the antivirus that you have always updated so that the features provided are powerful.
Do not forget to enable the internal firewall from the operating system or even an external firewall to increase the security of your computer.
Due to the spread of this virus through the Internet, it is better for techno friends to reduce the habit of downloading illegal software from the websites of illegal software providers that are widely available on the Internet.
This is because hackers often infiltrate Trojan horses in piracy programs. If you already have or need to download anti-theft software from these websites, just scan it with the antivirus you have.
And never disable the antivirus, as there may be times when the Trojan virus scan has not been detected. But in fact the virus is hidden and when the security of your computer is weakened. The virus attacks immediately. This is terrible!
