Has anyone else noticed a conflict with Security Center & RPM ?

Hi ... I'm running Vista Home Premium (32bit) and everything works great,
except for an occasional Window's up-date issue, but that's not an issue
currently.

My issue is that Vista's Security Center ( Malware protection) states Virus
Protection is On and Avira Antivir PersonalEdition is up to date and virus
scanning is on, but when I generate a 60 second Reliability and Performance
Monitor report, RPM's report states that " The Security Center has not
recorded an anti-virus product." and the cause is that " The Security Center
is unable to identify an active anti-virus applicatin. Either there is no
anti-virus product installed or it it not recognized. "

... but Security Center does recognize my AV and gives it a " Green for GO
", so what's the problem with the Performance and reliability Monitor ??? ...
TIA
