I have tryed everything and still have problems

First check Add/Remove programs for anything that does not belong there and then
you should read the tutorial in this Sticky thread < Hijack This Tutorial And How To Post Your Log File >

And then post your HijackThis log as a .txt file attachment. To do this save the log file and select manage attachments in a new thread to upload it. All running programs should be closed, including your web browser, e-mail, items in the tray, anything you can close... Close before running Hijack This!

Do NOT run Hijack This from the Desktop, a temp folder or choose run from the downloaded ZIP file. Place it in its own folder, for example C:\Program Files\HJT

 

Re: Attached log file as you asked

My message mislead you about (new thread). It was a cut & paste from the HJT tutorial which assumed you did not have a thread already. I merged you back into your original thread.

 

Re: Attached log file as you asked

You should have run EVERYTHING from the READ ME FIRST tutorial. You did not. I see no evidence that the online scans were run.

Run HijackThis and have it Fix the below lines:
O4 - HKLM\..\Run: [Windows service] slserv32.exe
O4 - HKLM\..\Run: [Sys29] C:\windows\system32\winohy32.exe
O4 - HKLM\..\RunServices: [Windows service] slserv32.exe
O9 - Extra button: (no name) - {08B0E5C0-4FCB-11CF-AAA5-00401C608501} - (no file)
O9 - Extra 'Tools' menuitem: Consola de Sun Java - {08B0E5C0-4FCB-11CF-AAA5-00401C608501} - (no file)

Are these two below lines what you expect for your start page and search page? If not, have HijackThis fix them too:
R0 - HKCU\Software\Microsoft\Internet Explorer\Main,Start Page = file:///C:/Documents%20and%20Settings/All%20Users/Documentos/Mis%20documentos/Mis%20Webs/Portal/HOME.HTM
R1 - HKCU\Software\Microsoft\Internet Explorer\SearchURL,(Default) = http://red.clientapps.yahoo.com/customize/ycomp_wave/defaults/su/*http://www.yahoo.com

Make sure you have enabled viewing of hidden file per the read me.
Reboot in safe mode and delete:
C:\WINDOWS\System32\slserv32.exe
C:\windows\system32\winohy32.exe

You should also get yourself over to Microsoft Update. You are way out of date with WinXP and with Internet Explorer.

 

Sounds good! Just check another HJT log yourself and make sure all those items I gave you to fix are gone and did not come back.
