V3 9.0 provides different types of scan and you can perform the scan depending on your need.
1) Smart Scan
You scan the pre-configured areas including the Windows folder, program files folder, and registry which are the most vulnerable to security threats. Smart Scan is convenient as it provides an integrated scan for malware without configuring additional scan settings. If system infection is suspected, and you want to scan the vulnerable areas quickly, you can perform Smart Scan.
2) Intense Scan
You can scan the user-defined system areas, which seem to be vulnerable to security threats as you use them a lot or the installed programs or the installed programs or files are frequently exposed to the security threats.
3) Real-time System Scan
You can scan files of your system in real-time. As Real-time System Scan scans the currently running files, if you need to manually scan specific system areas, you can also perform System Scan to double check your system security.
4) Scheduled Scan
You can scan the user-defined areas of the system at the scheduled time only.
5) Diagnostic Scan
You can scan the areas such as the memory, boot sector, process, and startup programs, which are most vulnerable but easily passed over.
6) Windows Explorer Scan
You can scan an individual file or file without opening the main program interface.
7) USB Flash Drive Scan
You can scan USB flash drive that is attached your computer.
