Well that all depends on how the program is coded. The point is if any AV program reports a virus, even if false positive, I'm not about to run an executable from an unknown/uncertified source.
If you want to run the log2vmx.exe fine, if not then archive and attach the vmware.log files and an new properly named .vmx file will be created from the .log files and attached to a reply. If you choose to use log2vmx.exe you'll also have to properly rename the file it creates.
