Just read in eWeek magazine that Giant Anti Spyware performed best on spyware removal than any other leading product (Spybot, AdAware, etc.). I tried to run it but it quits with an out of memory response. I also had just upgraded Win 2000 to sp4. Is there an issue with sp4 and memory loss? Has anyone run Giant Anti Spyware? I used a program called MaxMem to flush physical memory. At rest it is 58% free. As soon as I start Giant Anti Spyware it escalates until it gets to only 4,000 files scanned and then it maxes out the memory and quits.
