http://www.runscanner.net/why-runscanner.aspx Runscanner is a completely free windows system utility which scans your system for all configured running programs. You can use runscanner to detect autostart programs, spyware, adware, homepage hijackers, unverified drivers and other problems. I had ran this on two systems, both had left over files that were listed as File Not Found. I knew that a few were removed by PCTOOLS spyware doctor and antivirus program along with ThreatFire. These highlight in red just told the RunScanner to fix the problem, simply removes those marked in red. This seems to be more of advanced user tool, but the site has a lot of info and dbase on known threats. The program doesn't need to be installed.
