Sometimes it’s enough to

  • clear all TEMP-folders (via drive CleanUp AND best also manually)

Internet files ->Delete files, including OFFLINE files) and

  • empty java-Cache or
  • disable System Restore on Win ME/XP INCLUDING a REBOOT!! to get rid of it…

Test the file with OnlineScanners e.g. from Trend, RAV & KAV (see below) to get a more specific name (you need to temporarily pause AV-Resident Shield/Monitor/Guard to be able to scan the file online)

(If they all don’t show it as infected, please send it in a password-protected zip-file to virus (at) asw (dot) cz Include the Zip-password and a link to this posting in the mailtext)
