I just joined TechSpot today in hopes of finding a solution to the system memory problems I’ve been experiencing for several months now. I’m running Windows XP Pro MCE w/SP3 & IE8; in addition, I use Windows Firewall & AVG AV-Free. I’ve used Task Manager-“Programs” & “Performance” and other programs to try and find the large memory usage swings and perhaps pinpoint the location of trouble. I’ve seen very large fluctuations in CPU memory usage ranging from 3 or 4% all the way up to 100% & back down again, all within a few seconds. IE8 seems to have the largest memory swings, but other programs are also contributors. A couple of days ago, I downloaded SuperAntiSpware and the first run found and removed numerous Trojans & Malware. I noticed a link on the SAS website to FileResearch offering a free scan to “find out what’s running on your system.” I ran this program and found both expected and unexpected results; i.e., the unexpected showed 2 copies of “C:\PROGRAM FILES\INTERNET EXPLORER\IEXPLORE.EXE” running. Note: I just ran FileResearch again and now 5-copies are running! Also, iexplore.exe does not appear in the Add or Remove Programs listing that I can find, meaning I can’t uninstall it. Does anyone have suggestions?
