I have avast and somehow this program McAfee Security Scan Plus got downloaded into the computer , it could have been with adobe update or NoScript download… .
Will it interfere with avast, do I really needed it or should I delete it?
Many thanks…
it normally shouldn’t interfere, as it’s just a diagnostic tool; but if you’re on Vista/Seven you just don’t need it as security center (Action Center in Seven) do that job. Also, this McAffee tool is resident I suppose, so yes it could interfere. I personally would never install that, especially from a vendor producing his own security product, the goal after all being probably to get you to buy a McAfee suite 
ps: from the page here: http://us.mcafee.com/en-us/affiliates/adobe/landingpages/np681.asp?cid=72563
it doesn’t seem to be resident, so may be it’s okay.
what bothers me are the miscellaneous statuses, meaning you’re really protected only if you got McAfee on board ;D …otherwise at best “no issue found”

The McAfee probably came with Firefoxs’ Flash.
Without giving the correct permissions in NoScript, you do not even see the check box to allow/deny when you install.
Thanks for the feedback…
So, do I need it, will it interfere?, I certainly did not choose to downloaded it came with either of those two I mentioned…
again I don’t think it will interfere, but again, no you don’t need it at all ;D

Thanks Logos and YoKenny:
This is actually my dad´s computer, I´m in Spain visiting and I already opened a thread here:http://forum.avast.com/index.php?topic=62671.0
The viruses, 5 !!! that were in it are gone and with Essexboy´s help is now clean, but the reason SP2 is still there is because the computer is not able to download from windows update, the last update was about 18 months ago
According to Essexboy it seems the the edb log is corrupt and The only alternative left now is a repair install
can`t find the cd so since I´m leaving soon I´m tring to leave the computer as secure as it could be without the windows update … :-\ I installed a few programs and we´ll see…
well your best bet to keep it clean is using avast anti-virus and use super anti-spyware and anti malwarebytes, should be enough to keep viruses out ;D
