I was always interested in computer sciences, especially in data security and the theme, which is called nowadays "data science", since my early teens. Because I was lack of related literature, I tried to find something in the Web, so, virus injections was usual for me. That's why I've got quite high skill while dealing with viruses on my computer. When I heard about the website with different guidelines about virus removal and anti-virus programs, I've joined him with no doubt. Before coming into Virusremoval team as Editor-in-chief, I was working as cybersecurity expert several companies, including one of Amazon contractors. Another experience I have got is teaching in Arden and Reading universities.
