Virus question

I have been using bing for awhile and have had no problems, now every time I use it kaspersky finds and denies a virus. trojon.script.iframer i have no idea whats causing it, I also have no knowledge of viruses so I don't know if its a threat or false positive.

Also on my other computer which is using Norton, the action center says virus protection is turned off yet when I open it, it says the computer is secure. Other than that I'm not noticing anything wrong with my computers, but with something related to viruses occurring on two of my computers at the same time I'm hoping it's just a coincidence and not a virus in my router or something. Any info would be really appreciated

heuristic script.. your computer blocked it so it ok and norton bug... you can fix it by reinstalling or just leave it be... or change to something else.

Ok, thanks for the info.
