I am from Ireland. My parents bought me a computer when I was 11, and several month after I have got a virus on this PC. I decided to enter the INSA Centre Val de Loire university after being graduated from the school. This French educational institution was offering a brand-new cybersecurity course. After getting the master degree in cybersecurity, I've started working in as virus analyst in a little anti-malware vendor. In 2018, I've decided to start Virus Removal project. The main target of this site is to help people to deal with PC viruses of any kind.
