Our computer is permanently exposed to all kinds of threats, from cookies to viruses and from PUPs (Potentially Unwanted Programs) to registry errors. PC protection tools such as OSHI Defender not only detects and fixes all of these threats, but it also works permanently in the background to make sure that no new malicious software programs interfere with your system’s security and performance.

Wrapped up in an attractive and intuitive interface, OSHI Defender offers you various scan processes that will surely fit all your preferences. You will find a Quick scan, a Full scan (slower but more thorough), and a Custom scan. Once the scanning is complete, you’ll be presented with a list of all the threats detected. Divided into two main categories – Critical Level Threats and Low Level Threats – each suspicious item is categorized according to the kind of threat they represent, such as tracking cookies, PUP, Trojans, etc. You may then choose to fix them all or go through the list of quarantined items and decide which needs fixing and which represents a false positive. While testing this tool, the program listed two uninstall files as PUPs, so I recommend you to go through the Critical Level Threats list carefully before clicking on the “Fix Your Problems Now” button.

Now that your computer is clean and safe, OSHI Defender will stay on watch for as long as your PC is connected looking for new threats trying to find their way through your system. You can set up your preferred security level among Low, Medium, and High. A low security level will list all apps and settings labeled as suspicious; with a medium level of security, you will be aware of all potentially dangerous apps or critical system changes that are taking place on your PC, while the highest of the three levels will also let you know about all files that have been labeled as dangerous after checking them against the program’s own database. You can set the program to check your system thoroughly every day, as well as keep working in the background at system’s startup and for as long as your computer is active. You will be notified of any new threat trying to harm your system as soon as OSHI Defender detects it.

OSHI Defender offers you a powerful and versatile scan engine, a wide database of threats and malware programs, and a customizable 24/7 protection feature that will not only clean up your PC from any potential or certain threat, but will also keep it permanently clean and protected.
