Sorry there is always something to investigate, never take 'anything' at face value, do so and you risk a repeat performance of what has just happened, but with a different application since you are/have removed ST.
It doesn't matter how many starts it has got always investigate.
All of the programs you have mentioned have suffered FP detections that have causes issues, just ask Dan about AdAware 2007.
I would suggest you investigate dick imaging software that can take an exact image of your hard disk. I use Drive Image 7.1 (the last one before symantec bought the company) there is also Acronis True Image and others. I run mine once a week and if I have a crash or serious problem that will take more than 30 minutes to resolve I will restore the last image, this usually takes me about 15 minutes. You also need to ensure you regularly back up data you don't want to loose, documents, emails, email address book, bookmarks, etc. do this daily.
With a good back-up and recovery strategy you can recover from virtually anything in a short time without too much stress.
