Problems installing avira antivirus free edition

Hello,

I'm trying to install avira antivirus on a computer with win xp. It gives me error 0x15e, and it is unable to install. (First I had an error concerning the framedyn.dll, and I tried retrieving it from the cache, but it now gives me this error 0x15e. It seems I'm on no way to solving the problem.) The system has been modified on the path variables, and it might be that it is infected with viruses too. Could anyone help?

I got a hijackthis logfile:
