Hello, i am paris and i have that (or those) problem:
1) the computer is very slow
2) i tried to run a scan with TrendMicro Internet Security 2010 and the scan always stops at 9-10%
3) i tried to difragmetate(?) but nothing
4) i send an email to TrendMicro product support and they told me to try to do these:

{Run a Windows Disk CleanUp:
- Click on Start > Programs > Accessories > System Tools > Disk CleanUp

Delete temporary Internet files:
- Click Start > Settings > Control Panel > Internet Options > Delete Cookies and Delete Files (incl. offline files)

Try again to run a scan.

If not working, you can cut the process in the task manager.

- Ctrl+Alt+Delete > application > mark the scanning > press End task.

********************

Please then try the following fix.

In Windows XP
1. Click Start > Control Panel.
2. Click System
3. On the Advanced tab, under Performance, click Settings.
4. On the Advanced tab, under Virtual memory, click Change.
5. Under Paging file size for selected drive, make sure the custom size box is selected. You can enter the amount of memory you would like to reserve for Virtual memory by entering the initial set this to 4000 and maximum size set this to 4095.
6. Click Set

Reboot the PC and try again scanning the PC

You can also try the following:
Start > Run > type SFC /Scannow
Run the scan and try again
This may ask you for the original Windows Disk

If neither of those works please check that the Services are set to automatic
Use the services.msc to check if the services are running correctly:
a. Click Start > Run
b. Type in services.msc and press enter
c. Look for the following Services

i. Remote Access Connection Manager
ii. Telephony service
iii. Trend Micro Central Control Component
iv. Trend Micro Personal Firewall
v. Trend Micro Proxy Service
vi. Trend Micro Unauthorize Change Prevention

d. Right click on each of the items above and click on Properties
e. Click on the General tab
f. Change the Startup type to Automatic
g. Click on Apply and OK

Reboot and try again.}


6)I did eveythig except:
{You can also try the following:
Start > Run > type SFC /Scannow
Run the scan and try again
This may ask you for the original Windows Disk}

(i could not find Windows Disk)
but still nothing...
7)i downloaded and run Combofix twice and i have a ComboFix log which says
"Infected copy of c:\windows\system32\kernel32.dll was found and disinfected
Restored copy from - c:\windows\ERDNT\cache\kernel32.dll"
8) I downloaded and run MBAM and the scan result was "everything ok"
but the problem with the CPU still exists (with no programs opened the "processes" at the task manager shows "System 0-98" and " System Idle Process 0-98" every 2-3 seconds

Can somebody help me fix that (those) problem?
My pc has:
Windows XP Home Edition 2002 SP3
Intel pentium® D CPU 3,00 GHz
2,00 GB of RAM Physical Address Extension
1 TB HD (with 82% free)
Thank you

Since you have already run Combfix, I suggest you submit a DDS / HJT log for review



Please read the pinned topic titled "Preparation Guide For Use Before Posting A Hijackthis Log". If you cannot complete a step, then skip it and continue with the next. In Step 6 there are instructions for downloading and running DDS which will create a Pseudo HJT Report as part of its log.

You will also be instructed to create a Root Repeal Log

When you have done that, post your log in the HijackThis Logs and Malware Removal forum, NOT here, for assistance by the HJT Team Experts. A member of the Team will walk you through, step by step, on how to clean your computer. If you post your log back in this thread, the response from the HJT Team will be delayed because your post will have to be moved. This means it will fall in line behind any others posted that same day.

The HJT team is very busy and it will take awhile to get to your post
Please be patient and good luck
Mark
