Guest Mervita Posted February 24, 2009 Posted February 24, 2009 Hi! I've got a problem with F-secure Client security and Vista junction points named application data. The virus scan gets stuck in these recursive folder structures or the scan takes ~6h. The folder is: \\?\C:\Users\All Users\Application Data\ where Application data appears 14 times. I've understood that this might be a problem with a particular anti-virus software but at F-secure they did not know about this problem. So, has anyone stumbled on this problem with F-sec or another anti-virus prog. and what has been your solution? Furthermore, what is a correct number of recursive folders in this path? I'm thinking that there might be a program in my computer creating too many of these loops. Any help is greatly appreciated! WR, Mervi -- Mervita Quote
Guest MowGreen [MVP] Posted February 24, 2009 Posted February 24, 2009 Mervita, If there are 14 different Application Data subfolders at C:\Users\All Users then there may be some sort of file corruption going on. Configure F-secure to not scan the folder since nothing can be 'stored' there anyway and see if that restores the one subfolder that should be there MowGreen [MVP 2003-2009] =============== -343- FDNY Never Forgotten =============== Mervita wrote: <span style="color:blue"> > Hi! > > I've got a problem with F-secure Client security and Vista junction > points named application data.

Guest Sam Hobbs Posted February 25, 2009 Posted February 25, 2009 I am not sure I understand what you mean by "recursive folders" but the maximum size of a "path" is 260 (with some exceptions). In this context, a path includes the filename. The following might be too technical for you but it does provide all the details.

If you look at C:\ProgramData it contains a junction called Application Data which points to C:\ProgramData itself. [see it: run cmd.exe -> dir C:\Users /AL]. By itself this forms a loop. Since all roads to the "All Users" folder actually lead to C:\ProgramData (e.g. taking C:\Documents and Settings\All Users or C:\Users\All Users routes), applications that enumerate through this space will encounter the loop. In this case F-secure enumerates C:\Users\All Users and finds Application Data which it treats as a regular folder so recurses inside and continues enumerating. This brings it back to where it just was and eventually sees Application Data again and recurses inside... Vista adds security to deny everyone the ability to list folder/read data from most of the standard junctions - including Application Data. F-secure is not honouring them. So there's two ways that F-secure could be fixed to prevent this problem - ignore junctions themselves or honour the security permissions on the junction itself. Sincerely, Adrian Accinelli Quote
