Problem installling Acrobat reader

Hi, While trying to install acrobat reader Comodo (Defense+Alert) has given the following message:
Quote:
temporarily blocked this application. It has tried to execute shellcode as a result of a possible buffer overflow attack.
Application getPlusPlus Adobe.exe

This is typical of a buffer overflow attack. COMODO Defense+ has already isolated getPlusPlus_Adobe.exe from the rest of the system and will keep it isolated unless you skip this alert. However it is strongly reccomended to close this application and contact with its vendor for a fix

Computer is P4 3.0 OS is winXP SP3 fully patched

If you want to install, you can give exception to the file under
