WordFence has started flagging an malware warning on sites using Divi Booster (prior to version 2.7.6). Despite how alarming this seems, there is nothing to worry about.
Divi Booster includes a third-party library for detecting which browser is in use (as part of its CSS Manager feature). There is no issue with the code of either Divi Booster or this third-party library. Rather, the source code of the third-party library includes comments with a link to the manufacturer of each device it is capable of detecting. It seems that the website of one of the tablet manufacturers linked to by the library is being flagged by Google (and hence WordFence) as having malware.
There is essentially no risk to Divi Booster users from this. The only way to be affected by this would be to have manually been browsing the source code of Divi Booster and then to go into the code for the third-party library and click on the link to this particular tablet manufacturer (Vonino). As long as you have not done that, your site will not have been affected in any way. I have just released Divi Booster 2.7.6 which removes the offending link.
I hope that helps (and puts your mind at ease).
Please feel free to let me know if you have any questions, etc, either in the comments below or via the contact form. Thanks!
