It is more or less #1 but not entirely. In short: avast does detect some viruses but a large quantity of them doesn’t. Namely, only simple (string-defined) viruses are being caught.
I assume you mean just remove the entirety of "/NoExecute=OptIn" as above while leaving the rest intact?
Yes.
What function does the "/NoExecute=OptIn" provide? Was this line added my Avast originally?
No, this line was added by the XP SP2 installer. The NoExecute switch turns on/off the new Data Execution Prevention (DEP) Feature of XP SP2. http://www.microsoft.com/technet/prodtechnol/winxppro/maintain/sp2mempr.mspx
DEP is a very good feature but as already said, is currently NOT compatible with avast.
A fix will be included in avast 4.5 which is due Saturday, November 13th.
Hope this helps,
