Following a few sale purchases today and starting my downloads NORTON antivirus suddenly reported 'Suspicious behaviour' on galaxyclient.com (SONAR.AM.C!g24) I felt I had no choice but to allow NORTON to quarantine the galaxy client. Please tell me this was a false alarm and that my card details are safe. I assume after quarantine I assume I will need to do a complete fresh install of Galaxy client, obviously assuming it is indeed false alarm.
Cheers

GData (the anti virus I use) doesn't respond to Galaxy so it probably is a false positive.

Concering reinstalling (which might not be necessary because a file in quarantine isn't deleted, you should be able to move it back): Norton would just put it into quarantine again, you have to make an exception in the anti virus for Galaxy (I have no idea how you do that with Norton though, it's been over decade since I stopped using it after it gave me false positives on my old games).

Ah norton... picking on galaxy now lol, if you practice safe searching just delete norton and use the built in antivirus windows 10 has or if you are on 7 or something download microsoft security essentials, It works wonders and you will never have a false positive again like I have. oh and download malwarebytes as well if you go that route just for extra protection ;)

I hate how all these big antivirus programs treat a lot of game or game related programs as viruses, It's odd if you ask me.

Trust me on this one, if you are safe on the web and don't download stupid shit and have adblock but Reallllyyyyy hate these false positives you see then try my route and you will be more relaxed over time dealing with none of that crap like I have for the past 5 years.

Thank you for a solid reply. There have been many unhelpful comments but I appreciate yours and I think you are right. My experience with Norton have actually been a very good one. It chugs away in the background and very rarely gives me any grief. I think the GOG installer as you suggest is showing behaviour similar to what you may see in malware and the heuristics rules sometimes get it wrong. Thanks again :-) Thanks for the reply. I think you are right Norton will allow me to 'unquarantine' the application so thats likely the best way forward.

While still gobbling up more resources than most other AV programs, some of which perform better while giving less false positives. I still don't understand why you are such a Norton fan. But well, it's your computer that you are slowing down, so it's your decision.

By trial and error I found an involved way to make Nanny Norton take it out of quarantine. The download was then successful.

step 1 = remove Norton... for all other steps first see step 1
