I googled and found THIS
XP Home-op system-HP computer--
When I access HP help I get the following warning from McAfee virus scan
"Suspicious script has been detected C:\windows\PChealthctr\binaries\helpcntr.exe
Contains suspicious scripting activity and has been stopped.
Don't know what this is and if it has any impact on my Total memory being so low--I have ran adaware-spydoctor and the downloads nothing shows up...
