Need Help - search bar dont go away

Please do not post HJT logs unless we ask you to post them.
Also note the below items are browers:

c:\arquiv~1\intern~1\iexplore.exe
C:\Arquivos de programas\Internet Explorer\iexplore.exe
C:\Arquivos de programas\Internet Explorer\iexplore.exe

They MUST NOT be running anytime you use HijackThis. We specifically say that in the sticky threads. It is very important to follow those guidelines.

 

You need to go to Add/Remove programs and uninstall MessengerPlus3. It installs a load of malware on your PC including LOP.

 

Make sure you have system restore disabled and viewing of hidden files enabled (per the tutorial).

Run HijackThis and select the following lines but DO NOT CLICK FIX until you exit all browser sessions including the one you are reading in right now:
R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Bar = http://www.jtiwpaufewychhymgj.com/4gc_192e_Fz_nBygk3SvUhnmlrc1Ct2JgbEeGR5D16dopdv/a0pVtopRT23Gh9dF.html
O2 - BHO: G-Buster Browser Defense - {C41A1C0E-EA6C-11D4-B1B8-444553540000} - C:\WINDOWS\Downloaded Program Files\gbieh.dll
O4 - HKCU\..\Run: [Roadblue] C:\DOCUME~1\Pentium\DADOSD~1\ABOUTA~1\long less enc.exe
O14 - IERESET.INF: SEARCH_PAGE_URL=&http://home.microsoft.com/intl/br/access/allinone.asp
Boot into safe mode and use Windows Explorer to delete:
C:\DOCUME~1\Pentium\DADOSD~1\ABOUTA~1\long less enc.exe

Additional step to delete gbieh.dll:
- Click Start, Run, and enter cmd in the box and click OK. This opens a commend prompt windows.
- Enter the following command lines each followed by the enter key
cd C:\WINDOWS\Downloaded Program Files\
attrib -r -h -s gbieh.dll
del gbieh.dll
exit

Now reboot in normal mode and post a new HJT log. And tell us how things are working.

 

You're welcome. Your log is clean now.
