IT's running Apache V2.2.25, Windows is fully updated.

Do you think disabling PCT, SSL 2, SSL 3 via the registry will do the trick?

Thanks,

From what I can find Apache 2.2.3x is the minimum to fix it.

You should have already disabled SSLv2 and SSLv3 to mitigate the Heartbleed exploit. If you already have an SSL cert you will need to check the OpenSSL version used to create it as it may need updating
