We had installed SEP 12.1 RU1 on 50 PC's for testing various issues with the product before going for mass deployment.
We are tracking down all the issues with related to software Compatibility.
We found that we are not able to disable the Symantec Services from Services.msc
How to do it ?
I had also opened a case with mysupport. Case 415-774-913
This is required to check the false positive file & to upload to symantec.
If symantec delete or quarantine the file then it is difficult to submit.
Some Thirdparty softwares requires Antivirus to be disabled when installing, this is also not possible because of this issue.
