Re: puter dragin it's butt, what to clean up
Just cleaned one up. Removed all the "free" programs and task bar junk, but the one that did the most good was removing Microsloths Windows Search 4.0. It takes a ton of memory. Machine went from durned near useless to pretty snappy.
My recovery sequence is this.
1. Scan from a recovery (CD loaded) scanner. I use Kaspersky rescue.
2. Note every infection found and it's file location. This may be needed for manual registry repairs later.
3. Boot up in safe mode and run Trend Micro's HiJackThis utility. If you don't know what it is, look up anything you want to delete before you do it. This is a powerful utility that can brick a system in a heartbeat.
4. Boot up regular and using program install, remove the "freebies". Remove unused printer utilities while you're at it. Windows Search, Ask Toolbar, Google Toolbar, etc. are all core hogs that slow you down.
5. Run HiJackThis again and remove task bars, browser helpers, and such that can't be removed with program install.
6. Be sure there's a good virus scanner mounted and that the "freebies" that get forced in are all cleanly removed. (Norton, Mcaffee, etc.) I use Kaspersky Trend Micro, Computer Associates for commercial versions. Avast for the penny pincher.
(edit) just noticed your last post. Deleting cache will give you disk space, but slow down the browser till it regenerates. Most of the icons, banners, pictures etc on pages are retrieved from cache at about 100 times download spead as you browse.
Defrag isn't nearly as big an issue as it once was when disk wasn't cached in memory and memory was like 64 K bytes.
What is an issue is available memory and TSR (resident and running) programs. Slow program loads happen because the system has to send some of the memory contents down to disk to make room for it. That's called paging, and the whole works, memory, disk memory image, and control program is called virtual memory. Paging operations are about 500 times slower than memory operations.
I use Bart's PE and it's utilities to check and defrag a disk if needed. If anything untoward at all happens when Microsloths utilities are running, it'll brick the system.
hope it helps
