Re: Microsoft Security Center vs Third Party, eg. McAfee

1. If I wish to continue McAfee, I should remove both the Windows
Defender program which I must've added manually and the Malwarebytes-antispyware (free version); otherwise they interfere with each other? If you cannot update Windows Defender it is outdated, so yes, I would remove it. Malwarebytes Anti-Malware (free version) does not run in realtime as Defender was programmed to do, so it does not interfere with McAfee. MBAM (FREE VERSION) is an on-demand scanner that you can run when needed (as long as you keep it updated). If you are concerned with conflicts with McAfee, you can always temporarily disable McAfee for the duration of the MBAM scan and/or updating.
2. Running these together likely contribute to, or cause, my slow start-ups? IF Defender was trying to run it is possible that it was conflicting with McAfee.
3. Is there a way to have Malwarebytes placed simply in an inactive
state (BTW, this is what I thought it was doing all along), so that I
can access occasionally to "second-guess" my McAfee quick scans? That is what it does. My
Windows Security Center doesn't even acknowledge that Malwarebytes is
present, and correctly points to the McAfee protection.That is correct. It will acknowledge your realtime anti-virus scanner and firewall.
4. One last question, but probably not associated with the
security issue: Since my computer came with Win XP, SP2, should I have
added SP3? My assumption was it was an enhancement of SP2 with
security upgrades among them. Yes, please add SP3 and any other updates that you are missing. Visit Microsoft Update:
Make sure that you have all the Critical Updates recommended for your operating system, Office, and IE. The first defense against infection is a properly patched OS from Microsoft Update at update.microsoft.com. More info HERE.
