Hello, Got v3.0.684 running on WinXP SP3. Ran fine for a couple of months, when suddenly the PC began to freeze (not completely but all actions became very very slow). Even logging in has been taking a lot of time. Only thing that helps is disabling the antivirus and spyware protection from the client's menu. When doing this, everything comes back to normal. BTW, I found this in the ESET knowledge base. Although it's relevant for v4, I gave the explanation there a try, yet it didn't help. Appreciate any help. D.
