I got a copy of Spyware Blaster v. 2.3?? from the magazine Windows XP Answers. It installed O.K. It could not upgrade itself and directed me to the web site. I downloaded v 2.6. Tried to install it and had a problem. Uninstalled v. 2.3 and tried to reinstall v 2.6. Same problem. See below. C:\Program Files\SpywareBlaster\spywareblaster.exe An error occurred while trying to replace the existing file: DeleteFile Failed; code 5 Access is denied Click Retry to try again, ignore to skip this file (not recomm) or Abort. Retry does nothing. Please advise. Running Windows XP.
