Cannot view transfered file on msn messenger - Windows found that this file is potentially harmful

[Bandish]

Hi people,
I just got one file from my friend on MSN messenger. When i tried to open it directly from link, i got the error " Windows found that this file is potentially harmful. To help protect the windows, Windows has blocked the file." The file is safe, it happens everytime with .EXE, .Mp3s. How can i view all transfered files? Can anyone help?

Thank you in advance.

Check the Security Center and IE/SP2 - Privacy. This problem is caused by a Group Policy Object setting on Win2003 domain controller. This was forcing the default "attachment handling" to assume everything was "high risk", which pretty much blocks everything.
There is also an option to enable the security center options (including the "unblock" setting'), so you can see that on any files that are still blocked from being opened or executed, but at least you can save them to disk now.
Open Registry Editor and make following changes:

HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Policies\Explorer\PreXPSP2ShellProtocolBehavior (set to 1) controls the shell protocol.
HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Policies\Associations\DefaultFileTypeRisk(set to 0x00001806 - High Risk) controls the attachment handling.

Messenger blocks files that have the following file extensions

.ade .adp .app .asp .bas .bat .cer .chm .cmd .com .cpl .crt .csh .exe .fxp .hlp .hta .inf .ins .isp .its .js .jse .ksh .lnk .mad .maf .mag .mam .maq .mar .mas .mat .mau .mav .maw .mda .mdb .mde .mdt .mdw .mdz .msc .msi .msp .mst .ops .pcd .pif .pl .prf .prg .pst .reg .scf .scr .sct .shb .shs .tmp .url .vbs .vsd .vb .vbe .vsmacros .vss .vst .vsw .ws .wsc .wsf .wsh

You can easily fix it with A-patch. A-Patch was designed to make patching Messenger.

You can allow this blocking of files from windows by following method:

• Open Registry Editor (Regedit.exe))
• Browse the following key in the registry:

  HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Associations

• If the Associations key doesn't exist, then create new key under policies (Right-click > New > Key)
• On the Edit menu, click Add Value, and then add the following registry value: "LowRiskFileTypes" (String Value, or REG_SZ type)
• In the value data area paste the following list:

  .exe;.bat;.com;.cmd;.reg;.vbs;.inf;.msi;.htm;.html;.swf;.js;.mp3;.mp2;.ape;.apl;.flac;.shn;.mpc;.mp+ ;.wma;.ogg;.mp4;.aac;.voc;.mid;.mac;.cda;.kar;.midi;.rar;.zip;.wav;.jpg;.gif;.png;.bmp;.jpeg;.doc;.x ls;.pls;.pub;.dat;.html;.htm;.avi;mpg;.mpeg;.nfo;.txt;.torrent;.diz;.ppt;.m3u;.sfv;.tar;.htt;.mht;.a sp;.aspx;.tiff;.rtf;.ini;.cab;.ico;.icl;.ip;.iptheme;.msstyles;.theme;.dll;.psd;.vbs;.swf;.php;.xaml ;.iso;.bin;.cue;.xml;.par;.par2;.ace;.arj;.lzh;.7z;.gz;.bz;.uue;.bz2;.jar;.z;.ade;.adn;.adp;.aia;.im g;.date;.aip;.ait;amf;.ani;.aob;.asf;.csv;.fla;.pxr;.wmv;.nrg;.mov;.sav;.xhtml;.php5;.pxr;.m4a;.qxr; .h;.cpp;.pdd;.rle;.dib;.eps;.jpe;.pcx;.pdp;.raw;.pct;.pict;.sct;.tga;.vda;.icd;.vst;.tif;.tpl;.log;. prx;.cdf;.nls;.ax;.msc;.cpl;.EXE;.BAT;.COM;.CMD;.REG;.VBS;.INF;.MSI;.HTM;.HTML;.SWF;.JS;.MP3;.MP2;.A PE;.APL;.FLAC;.SHN;.MPC;.MP+;.WMA;.OGG;.MP4;.AAC;.VOC;.MID;.MAC;.CDA;.KAR;.MIDI;.RAR;.ZIP;.WAV;.JPG; .GIF;.PNG;.BMP;.JPEG;.DOC;.XLS;.PLS;.PUB;.DAT;.HTML;.HTM;.AVI;MPG;.MPEG;.NFO;.TXT;.TORRENT;.DIZ;.PPT ;.M3U;.SFV;.TAR;.HTT;.MHT;.ASP;.ASPX;.TIFF;.RTF;.INI;.CAB;.ICO;.ICL;.IP;.IPTHEME;.MSSTYLES;.THEME;.D LL;.PSD;.VBS;.SWF;.PHP;.XAML;.ISO;.BIN;.CUE;.XML;.PAR;.PAR2;.ACE;.ARJ;.LZH;.7Z;.GZ;.BZ;.UUE;.BZ2;.JA R;.Z;.ADE;.ADN;.ADP;.AIA;.IMG;.DATE;.AIP;.AIT;AMF;.ANI;.AOB;.ASF;.CSV;.FLA;.PXR;.WMV;.NRG;.MOV;.SAV; .XHTML;.PHP5;.PXR;.M4A;.QXR;.H;.CPP;.PDD;.RLE;.DIB;.EPS;.JPE;.PCX;.PDP;.RAW;.PCT;.PICT;.SCT;.TGA;.VD A;.ICD;.VST;.TIF;.TPL;.LOG;.PRX;.CDF;.NLS;.AX;.MSC;.CPL;
