thewelkinsuite.exe (version 29.7.4) was detected as a virus and quarantined by our corporate antivirus Trend Micro OfficeScan with 'Unauthorized File Encryption' thread when I just created a brand new project and pulled a few Apex classes.
I'm contacting my IT support to try to get it identified as a false alarm, but you have to reconsider some of the background functionality in TWS to avoid this misdetection by Trend Micro or any other antivirus.
