The Panda's virus scanning engine performed well in my malware tests, but did not achieve a 100% detection rate in all cases, namely:
Detect 95% of all non-running sample malware files during the full system scan.
Block 100% of the ransomware samples running (including WannaCry ransomware).
100% removal of pre-installed spyware.
Panda's separate cloud-based scanning tool called "Panda Cloud Cleaner" enabled an advanced system scan by detecting suspicious, ingrained files.
Although the Panda Dome antivirus did not show a 100% detection rate for all types of malware, it blocked the most destructive files including ransomware, and securely deleted it.
