libstdc++ differences ( post #1)

i am trying to install BitDefender in my laptop. However a dependency issue happened. the package needed the libstdc++-librc6.2-2.so.3....

well, i used the install packages in gui 'configure you computer' section and found out that i have to install libstdc++2.10-2.96-0.83mdk....

i have downloaded it already. however through the course of the search i can't believe that mandrake won't have a gcc library so i searched through the mandrakelinux.com and found out that i have the available packages:

libstdc++5-3.3.2-6mdk.i586
libstdc++5-devel-3.3.2-6mdk.i586

so i am not sure if i have a problem with my installers . if not, what is the difference with libstdc++5-..... and libstdc++2.10-....... ? how should i install the BitDefender? should i really need to install the libstdc++2.10-2.96-0.83mdk? would there be any conflict?

PS
yes, most of the guys told me that i dont need to have an antivirus. well, iam just safety conscious.
why BitDefender? -well i dont have much time when in comes to tweaking. a bit of a concern using fprot and clamav(i heard from reviews).

libstdc++-librc6.2-2.so.3 is a shared library installed by gcc-2.9, an older version of gcc. It isn't installed if you install gcc-3

sir,

1. do you mean that the two libstdc's are different?
2. that the new versions are not 'backward' compatible?
