Virus/Spyware/Malware removal results
I've completed the 15-step process for cleaning malware/spyware, etc., as recommended. I've included the requested attachments. Briefly, here are the results of the cleaning steps:
step 1: n/a, as I wasn't running any of the indicated programs
step 2: n/a, as I was already running McAfee, with spyware and firewall turned on -for all the good it was doing me, as it turns out :-(
step 3: completed successfully
steps 4&5: completed successfully
step 6: completed successfully -trojan SrvAdmin.A found
step 7: completed successfully
step 8: n/a -I already had Ad-aware personal, with latest updates.
step 9: completed successfully
step 10: tool1/2/3 all completed successfully
step 11: completed successfully -no rootkits found
step 12: completed successfully -combofix log attached
step 13: partial success: McAfee wouldn't run in safe mode

. It would display it's startup splash screen for a 1/2 second then disappear. Nice, huh? I booted back into normal mode and ran it from there, then rebooted into safe mode for step 14.
step 14: completed successfully. Note that AVG again found the SrvAdmin.A trojan, and even though I checked 'quarantine' as directed (I double checked this before and after the scan) the log still reported 'no action taken' [perhaps because it's already quarantined from the first scan?]
step 15: completed successfully
One lesson learned from this is that McAfee isn't nearly as good as I thought it was. I knew it wasn't perfect, but between it completely missing two different trojans (whataboutadog and SrvAdmin.A), not being able to run in safe mode, and missing a whole lot of spyware that Ad-Aware and some of the other tools you had me run found, I must say I'm pretty disappointed in it.
Thanks again Howard for all your help with this -you and your fellow experts provide a real service to the rest of us, and it's most appreciated.
