No, don’t delete it. Let it there, right click the file and choose scan again.
If the file appears clean, most probably it was a false positive.
Then you can restore the file to the original place.
If not, if it is indeed infected, it won’t harm staying in Chest (it’s safe), you can wait some days to repeat the process above to check if indeed it’s not a false positive.
It won’t harm if:
- Disable System Restore on Windows XP: http://support.microsoft.com/default.aspx?scid=kb;[LN];310405
Then after step four, enable it again.
- Clean your temporary files.
- Use a-squared, Free AVG Antispyware, SUPERantispyware or Spyware Terminator (trojan removers).
