Trojan.maljava!gen23

It happened for the first time at 11:20 or so.

Four files were in c\window\temp folders, starting with

jar_cache(string of #'s).tmp

 

Norton said they were blocked, I emptied the temp folders, and thought it was done.

About 5 hours later I got 4 new messages with different .tmp files in the c\windows\temp folder.

 

I dumped the temp folder again, and went to java and updated it through the website.

 

I wanted to know if these are isolated seperate incidents, or a symptom of something else on my computer that is not being caught?

 

I have windows 7 32 bit os.

I have a flash drive.

 

Thank you in advance, quads.
