While backing up the contents of my Machform folder to my computer HD, Kaspersky Anti Virus flagged and deleted three files from different locations with descriptions as follows:
1) \lib\braintree\Braintree\Exception\readme.phtml; Backdoor.PHP.Agent.ce
2) \lib\swift-mailer\classes\Swift\Mime\ContentEncoder\footer.php; Backdoor.PHP.Agent.ce
3) \data\form_10682\files\1.php; Backdoor.PHP.WebShell.gl
What I would like to know is, are these likely to be false positives or genuine virus files that have somehow got into my installation?
