Removing other Antivirus entries

[drvnguy]

I am currently using AVG just fine but recently had tried Kapersky and Nod32 by eset . When i boot my computer the red x in the toolbar tells me my nod32 2.7 needs to be updated evan though i have uninstalled it .Can i remove all reg entries and other files associated with Nod that it forgot ?.. is there somewhere i can go to delete these files . evan in the security centre under malware option it still shows that i have 3 scanners but only 1 is active .

Thanks for any tips
