Listed Threats require manual removal, not listed on site

 Earlier today, the MacPro has been getting into a total system freeze, spinning ball syndrome.

Start a video, and halfway it stops.

Try to access anything regardless the Dock, Finder,etc is locked up action, then force it down.

Insert OS disc to scan drives, and it says they are OK.

During a couple freeze actions, a pop-up that vanishes before it can be viewed fully says something about smart drive sensor?

I can't find this mentioned in console report.

This lead me to think a rare virus got me, and why I'm here.

RE-SCANNED / did not find an issue

Played the application, and there was a hang issue on start panel, but it played Ok.

*** The following are documents roughly 25k and are part of an application downloaded Nov 30 10.

Apparently all from the same application.

I can't nail down what application it is.

I even went as far as searching the date in SpotLight, but could not find the possible source.

Enter any term of threat or file comes up empty in Spotlight.

My logical thinking simply wants to delete the cache file that contains these threats.

Any downside of doing this? 

If threats are truly connected to some single application, I really don't care if it gets destroyed in the process.

Thanks for the help.

I remanufacture aircraft manually, but I dislike digging too deep into memory systems.
