Who we are
Greatis Software is a small, independent software company. Since 1998 we have made system software and cyber security tools for Windows. Our best-known program is UnHackMe, a malware remover that finds what other scanners miss.
Greatis Software LLC is registered in the USA.
UnHackMe in numbers
How it started
Greatis Software was founded in 1998 by Damien Hawk, Dmitry Vasiliev and Irina Sokolova. Our first successful program was RegRun Security Suite, a toolkit that controls what starts with Windows and protects it from unwanted programs.
Working with RegRun users, we saw the same problem again and again: malware that hides so well that antivirus programs cannot see it.
UnHackMe: from rootkits to every kind of threat
In 2005 we released UnHackMe, one of the first tools made to detect and remove rootkits, malware that hides itself inside Windows.
Threats changed, and UnHackMe changed with them. Today it removes:
- Trojans and hidden malware
- browser hijackers that change your homepage and search
- browser notification spam
- malicious services, scheduled tasks and startup items
- unwanted browser extensions
- fileless malware of any kind
UnHackMe can clean a computer in three ways:
- In working Windows, like any other program.
- Offline, with UnHackMe Warrior: a bootable solution that starts the computer without Windows, so malware cannot run or defend itself.
- Remotely: UnHackMe saves a report of the computer (a RegRun log file). Our specialists study it and send back a special cure file (an RNR file) that removes exactly what they found.
A new home
In 2022 Greatis Software moved from Russia to the USA. Today the company is led by Victor Pankratov, our CEO.
UnHackMe Safety Reports
In 2018 we started UnHackMe Help, and in 2026 we launched Greatis Software IntelDB, our database of threats and safe sites. It powers free safety reports: you can check whether a website is safe and learn how to remove what it left on your computer.
The reports describe websites, not their visitors. To learn how we check sites and decide on a verdict, read our Methodology.
