I seem to have two files quarateened that I believe have been around for sometime. They appear to have only recently been quarantined though. The first is: C:\Windows\System32\drivers\secdrv.sys Which I believe is a macrovision security driver but identified as win32\nulprot trojan. The second is: C:\Program Files (x86)\Common Files\InstallShield\UpdateService\ISUSPM.exe -startup which is identified as win32\Bagle.QC worm Maybe they really are viral but I am fairly sure they have been around for a long time. Could they be false positives??
