Hi!, I just installed my windows XP and wanted to use Windows Defender as
antivirus software, then after installing the Security center of WXP kept
telling me that I needed an antivirus and my system is at risk, then I
thought that Windows Defender wasn´t actually a real time antivirus but a
secondary program so I installed Nod32 and Windows stopped telling my system
is at risk, but the thing is that my system, though still relatively
operational, got
very slow and unstable with both Nod32 and Windows defender installed.

I then disabled realtime scan in Windows defender but the problem
remained, I even unchcked the entries of Windows Defender in the msconfig
start tab and nothing. I also notice some processes associated with Windows
Defender in the Taskbar.

My problem is, what should I do?. Should I uninstall Windows defender
and keep only Nod32 or should I uninstall Nod32 and keep Windows Defender as
my main antivirus although the Windows Security Center doesn´t recognizes it
and tells me my system is at risk because there´s no antivirus software on?.
I wish I could only use Windows Defender but since Windows Sec. Center
doesn´t recognizes it, it makes me doubt about if it´s really an effective
antivirus.

Please Help, Thanks

Windows defender is an anti spyware not an anti virus...

1. Leave Defender and NOD32 installed.

2. Run a /thorough/ check for hijackware, including posting your hijackthis
log to an appropriate forum.

When all else fails, HijackThis v1.99.1
(http://aumha.org/downloads/hijackthis.zip) is the preferred tool to use.
It will help you to both identify and remove any hijackware/spyware with
assistance from an expert. **Post your log to

http://aumha.net/viewforum.php?f=30, or other appropriate forums for expert
analysis, not here.**

If the procedures look too complex - and there is no shame in admitting this
isn't your cup of tea - take the machine to a local, reputable and
independent (i.e., not BigBoxStoreUSA) computer repair shop.
