Today Bitdefender blocked access to Bitsquare on my computer and when I uninstalled the Bitdefender, it also deleted the exe file. So I just wanted to share this in case someone might find it useful.
AVG works good from my experience. Many AV software is just crap and have lots of false positives. Better invest the money to move to OSX or Linux instead of running an inherently insecure system which requires AV software which often does not help much but mainly lowering performance of your OS (not recommending though to use Windows without AV).
