Hitman Pro is a second option malware scanner, which is designed to remove the leftovers of malicious software or files that were not removed/detected during your regular antivirus scan. It uses cloud computing technology and has an impressive malware detection ratio. It is especially good at rootkits' detection. This program doesn't slow down the system and can be used alongside other security programs.
Hitman Pro offers 'Free Scan' and 'Behavioural Scan' that check computer's security measures and look for viruses or suspicious files. Usually, this program takes less than 5 minutes to check the system. If it detects a suspicious file, it uploads the file to the "cloud". The file is then scanned by five antivirus engines: Dr.Web, Ikarus, Emsisoft, Prevx and G Data that are well-known names in computer security industry.
Another good thing about this software is that you don't need to install it on your computer, so you can avoid conflicting security programs and computer crashes. It can be run straight from a USB flash drive, a CD/DVD, local or network attached hard drive.
However, it requires a working Internet connection, which is a must for detecting malicious files and uploading them to the "cloud" for scanning.
Hitman Pro removes infections for free. Its free license is valid for 30 days. After that, you will have to buy it, which is actually not a big deal because it's rather cheap. However, this program doesn't have a real-time protection what means that it is best to use it in conjunction with antivirus software.
The current program's version is Hitman Pro 3.7.
