Hello, Erin... I would not go on the web without a firewall of some description; I cannot tell if you have Windows Firewall activated. I use ZoneAlarm, and it is not a sys hog for me, in fact vsmon.exe hardly ever stirs as far as processor time goes. May I suggest that you restart Zonealarm then got into Task Manager, Processes tab, and check how much CPU time vsmon.exe uses. It pretty much should show 00.
Is your version up-to-date?
I notice that you have AVG AS, SAS [superantispyware] and SpyBot... actually, is AVG still providing updates for AVG AS 7.5?
I would cut that down to just one spyware scanner; actually, for the longest time I ran no resident spyware scanner at all, just had an on-demand one or two waiting in the wings. But now I use Avast, and one is incorporated with the AV scanner, so... actually, I have Spybot ready and updated, but I seem to be able to stay clean so I have only run one scan recently. Just to see. Look, try being sensible with online link-clicking, and run no active AS. Just keep Spybot updated in case.
Tea-timer is not a load, though, it just monitors for attempts to mod your registry.
"128 mbs of ram and 480 whateverbites processor"... I do see what you mean... 480 whateverbites is very slow buy today's stds, and 128 mbs of RAM is not much. If you took the time to wander into your local computer wrecker/reseller shop I bet you could get a 500MB stick for not much more than a smile. Okay, ten bucks. And that would speed up your sys more than any other thing. You see, your log is clean...
Frankly, though, you do need an AV service.... Avast? and then you could ditch AVG AS, and shut off SAS.
Finally, a cleanup. I bet you don't have many Gigawhats on your hard disk, either. Open My Computer, rclick your C: drive, choose Properties. See the Disk Cleanup button? -hit it. Do you have much free space? Under a Gig and Windows is going to spend time looking for places to write stuff. Empower yourself and delete files you don't use, photos you dld from the web cos they were cute 3 years ago, but now... See the Tools tab? Press Defragment Now. Repeat this for any other drives you have, D: etc.
