There is a very good chance that you are seeing the effects of a
hijackware infection!
NB: If you had no anti-virus application installed or the subscription had
expired *when the machine first got infected* and/or your subscription has
since expired and/or the machine's not been kept fully-patched at Windows
Update, don't waste your time with any of the below: Format & reinstall
Windows. A Repair Install will NOT help!

Otherwise...
1. See if you can download/run the MSRT manually:
http://www.microsoft.com/security/malwareremove/default.mspx
NB: Run the FULL scan, not the QUICK scan! You may need to download the
MSRT on a non-infected machine, then transfer MRT.EXE to the infected
machine and rename it to SCAN.EXE before running it.
2a. WinXP => Run the Windows Live Safety Center's 'Protection' scan
(only!) in Safe Mode with Networking, if need be:

2b. Vista or Win7=> Run this scan instead:

3. Now run a thorough check for hijackware, including posting requested
logs in an appropriate forum, not here.

If these procedures look too complex - and there is no shame in admitting
this isn't your cup of tea - take the machine to a local, reputable and
independent (i.e., not BigBoxStoreUSA) computer repair shop.

1.2
gigs of RAM. When I look in Task Manager, the Performance tab shows CPU
usage almost nearly constant at 100%, although it spikes downward to a
few
tens of % occasionally. This doesn't sound correct.
I've got CA (Road Runner) Security Suite running, plus
MalwareByte's-AntiMalware, plus Ad-Aware 2009 installed. None of these
show
any viruses, etc. on this machine (occasionally a tracking cookie). Just
today I uninstalled SuperAntispyware Professional simply because I could
never get the program to open up, even after a 10 minute wait. The
program
used to run just fine. I've never, ever used a Registry Cleaner on this
computer as I've been warned they can do more harm than good.
I've tried Disk Cleanup on the C drive but that program basically hangs
up.
After 5 minutes of waiting for it to calculate how much disk space would
be
save, I closed it. The C drive has 15 Gbytes of free space and 45 Gbytes
used. RAM seems to show over 500 MB available. I haven't defrag'ed this
drive in a long time.
Can someone tell me if 100% CPU usage is the reason why everything takes
forever to open, and what would cause such CPU behavior? I have had what
I'd
call `cooling problems' due to a dirty fan (fixed) and poor airflow
underneath the computer so I took care of that by cleaning the fan and
propping the laptop up so more air can flow under it. Is it possible the
CPU
got damaged from excessive heating? (The CPU shut down a few times a
month
ago, seemingly because it got too hot, but that no longer happens).
Thanks in advance................Paul C.
