it may not be in the top tier but it is still respectable. in PCmags feb 2019 review, when they computated an aggregate score of all AV software and the 4 major testing lab results, panda scored a 8.9. for a comparison, windows defender scored a 8.7. fsecure scored a 8.6 and gdata scored a 8.9. these are aggragated independant lab studies putting panda in a respectable crowd. panda scored better than windows defender.It also comes with "100% virus detection rate"
and when pcmag ran their own personal malware test, panda scored a 9 (90 percent). windows defender scored an 8 (82 percent detection). eset scored 8.8.
and considering how light it is, that makes it attractive.
Panda Free Antivirus boasts an attractive user interface and an unusual USB vaccination feature, but it no longer includes protection against dangerous or fraudulent websites and it fares poorly in our hands-on tests.
