Used to use both CVA and Secunia to check for vulnerabilities and needed updates and patches.
Last scan with CVA I only saw one new update.
Wondered what others use for scanning for software updates, I use these 3
UpdateChecker from File Hippo, It only shows what files it offers for download but has been very accurate on full releases and beta updates.
UpdateNotifier from CleanSoft.Org Also very good and found software I forgot about.
The last one is a beta from cnet called Tech Tracker. Being beta found several betas posted as full release and also incorrect version numbers.
Wish I knew what files they were looking at so I could clean them out. Oh I do use Comodo System Cleaner along with several other cleaners both file and registry.
