AVAST AntiVirus Report Error

I have been a happy SB user for more than a year, updated to SB 3 sevral days ago and thought everthing was configured properly.
Changed my AV program to AVAST Home yesterday, ran 1rst "deep" scan and all OK, ran a 2nd "deep scan + archive scan" today and got 2 files reported as "corrupted".
"C:\Program Files\JavaSoft\JRE\1.3.1_01\lib\rt.jar\META-INF\MANIFEST.MF [E] ZIP archive is corrupted. (42125)

C:\Program Files\JavaSoft\JRE\1.3.1_01\lib\jaws.jar\META-INF\MANIFEST.MF [E] ZIP archive is corrupted. (42125)"

Are these files associated with SB? What should I do about them?

 

It is possible that you are getting a false positive you might want to run an online scan to double check especially if your previous AV didn't report these files.

This is a normal behavior. The avast ZIP unpacker generally warns on JAR files because they are basically ZIP files with corrupted checksums...

You don't have to worry about this one, really...

 

Is it possible to have a virus in one of these files which is not scanned due to corruption. I'm guessing if possible the likelyhood is minimal otherwise Avast would handle it different; ie. error report the corruption but still scan for nasties?

Congrats on the string of 100% VB100's.
