If you are not sure if your PC is safe (especially if you hold cryptocurrencies), you can try to scan for viruses and malwares, in this tutorial i will use Malwarebytes Anti-Malware:
Disclaimer:
- You can use whatever Anti-Virus / Anti-Malware Software you like, i found Malwarebytes is one of the easiest to use.
- If you have another Anti-Virus Software installed, the installation of a second Software of this kind can lead to problems (Please do not install 2 Antivirus Tools simultaneously).
Download the software on www.malwarebytes.com
Install the software:
Accept the administrative Dialog
Read the License Agreement and Install (choose Advanced Options for a specific install location):
Open Malwarebytes, and click on Scan Now:
The updating and scanning process can take up to an hour (depending on your hard drive speed / capacity):
In the scan results, you can choose which files to put into quarantine (delete from your pc):
To finish the process, you have to restart your PC.
Congratulations! You have removed (most of) the viruses on your computer:
Hint: You can turn off automatic startup of the Malwarebytes software, if you wish:
Especially in times of known security risks and zero day exploits (i.e. Spectre and Meltdown, see https://spectreattack.com/) it is most important to have installed the latest updates for your browser, your flash player, java, and your operating system.
Greetings and stay safe,
