Sucuri Scan showing Malware in Cache file

Hi there, I grabbed the latest version of this plugin and ran it against https://sitecheck.sucuri.net which showed a malware in one of the cache files. Figured maybe it was old so I removed the plugin and did an rm -r to the cache folder (rescanned it and it was fine) than went ahead and reinstalled the plugin then did another can and found the malware once more.

Here is the page on what it found. This a false positive or something I should be concerned about?
