Free McAfee SiteAdvisor V3.0.1.152 has fixed the "abandoned temporary file" defect.
Fixed Defect:
The Free McAfee SiteAdvisor SACore COM Server component, McSACore.exe before V 3.0.1.152, created three temporary files at each system start and did not remove them at normal shut down. This defect began with version 2.9.0.239 of McSACore.exe.
These temporary files were created at each system start up and then abandoned at shut down in C:\WINDOWS\Temp in this XP Home SP3 IE8 environment. If you reboot once a day you see 90+ of these created each month.
Examples were:
sqlite_3V3yZ00uo2GPpSU
sqlite_E8MmQZdN247B4jG
sqlite_QfmvbhWl45fNDhh
I can not speak to “Upgrade without Permission" defect, since I downloaded V 3.0.1.152 manually.
