My mom's XP computer slowed down quite a bit about May. I suspect malware, but haven't been able to find anything with AVG free, Spybot S&D, AdAware, AVG antispyware, SAS, Housecall, Bit Defender, Panda (the last three online--Panda still finds some registry trace from an old problem, but doesn't give a location in registry), HijackThis, or a few of the specialized tools.
AVG seems to be scanning and updating regularly, from the event log, except sometimes when the program changes and Mom neglects to check the box for Zone Alarm to allow the new version to update. Recently I notice that the control center icon in the system tray does not appear at startup, even though all three lines for AVG are checked on the Spybot Startup list. The process list has avgemc but not avgcc. I can double click the desktop icon and the icon appears in the tray. Then the control center window will say it is fully protected, but I worry it is only fully protected after I started AVG manually.
Maybe AVG works differently on ME. I quit control center and confirmed quit. Then the icon disappears and avgcc goes from ``close program'' but not avgemc or AVG Test Center. Then I started it again from the desktop and the test center appeared instead of control center. Choosing the link for control center, that screen comes up saying ``no available components'' for half a second, before they fill in the the message says fully protected. At what point have I restarted real-time protection, when I double click avg, or when I choose control center and AVG Control Center appears on the screen and in close program. (When I minimize control center, the id in close program changes to avgcc.)
Another issue with the tray is that the little arrow that unhides the icons sometimes turns into a blank space for a while, and it becomes impossible to find out what icons are hidden.
I can literally find no new entries in hijack this from when the computer was starting up in a normal amount of time back in, I think, February to mid-May.
I removed avast! from the XP computer, because it seemed to be starting some process, even though I unchecked all the entries in the startup list. On ME, the startup list seems to keep avast! from running. AVG and avast! don't seem to interfere with each other's definition files, but the avast! full system scan maybe would take twice as long if you don't turn off the avg real-time protection and only use avast! during the scan. Anyway, I think I uninstalled avast! after the computer had slowed down, and avast! had not detected anything either.
