Can anyone please tell me which files to remove, if any?

Many thanks
Nicole

Re: Computer extremely slow - can you please help tell me what's wrong?
 

It looks like you have two antivirus programs, Mcafee and AVG, running at the same time which can really slow down a computer. One of them needs to be removed. Personally I like AVG much better than Mcafee. Which ever one you keep, make sure it is up to date.

Re: Computer extremely slow - can you please help tell me what's wrong?
 

Thanks Darrin...I really appreciate your help! I have removed Mcafee as suggested, and kept AVG.

I still feel something 'isn't quite right'. Can you see anything else that looks sinister in the HJT log file? When I type in www.trinitigiftshop.com (an online store I run), the following appears in my URL bar:

http://uk.search.yahoo.com/search?fr...ftshop.com&y=y


It's as though something has hijacked my browser. What do I do - help??!

Re: Computer extremely slow - can you please help tell me what's wrong?
 

Darrin, I found this information on the net with regards to uk.search.yahoo.com (which I feel is hijacking my browser).

Can you interpret for me what this person is saying (I'm wondering how I remove any corrupt files as I'm not a real techie). Thanks for any help.!

Sorry - here's the info on uk.search.yahoo.com:

Description

VBS.Qhosts is a trojan that attempts to redirect Internet domain names, mainly for intercepting queries to search engine web pages such as www.google.com.

The trojan is loaded from a web page, which exploits a vulnerability in Microsoft Internet Explorer to run script with unrestricted access to the system. The vulnerability is addressed in the following Microsoft security bulletin and associated cumulative patch:


http://www.microsoft.com/technet/sec...n/MS03-040.asp

Once the malicious script is executed, the trojan will drop a file called AOLFIX.EXE into the Windows temporary directory. It then creates a batch file that will proceed to execute AOLFIX.EXE and delete it after the execution.

AOLFIX.EXE is a batch file compiled into a Windows binary executable by the "bat2exe" utility. Once run it will check if a file called %windows%\winlog exists. If it does, the trojan does nothing and will exit. If the "winlog" file is not found the trojan tries to modify the following registry keys:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\MSTCP\
"EnableDNS"="1"
"NameServer"="69.57.146.14,69.57.147.175"
"HostName"="host"
"Domain"="mydomain.com"

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\
"ProxyEnable"=dword:00000000
"MigrateProxy"=dword:00000000

HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\
"Use Search Asst"="no"
"Search Page"="http://www.google.com"
"Search Bar"="http://www.google.com/ie"

HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\SearchURL\
""="http://www.google.com/keyword/%%s"
"provider"="gogl"

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Search\
"SearchAssistant"="http://www.google.com/ie"

These settings will make an affected system use the IP addresses 69.57.146.14 and 69.57.147.175 as its DNS servers. They also change the domain name to host.mydomain.com, disable any IE proxy, and set the IE search page to point to www.google.com. These DNS name servers are probably used to redirect name queries to servers run by the trojan's author.

The trojan then checks if %windows%\system32\drivers\etc\services exists. If it finds this file, it will proceed to modify the following registry keys:
(note that the presence of the "services" file generally indicates that the trojan is dealing with Windows 2000 or Windows XP.)

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Tcpip\Parameters
"DataBasePath"=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,74,00,25,00,5c,00,68,00,65,00,6c,00,70,00,00,00

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\Tcpip\Parameters
"DataBasePath"=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,74,00,25,00,5c,00,68,00,65,00,6c,00,70,00,00,00

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Tcpip\Parameters\interfaces\windows
"r0x"="your s0x"

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Services\Tcpip\Parameters\interfaces\windows
"r0x"="your s0x"

The DataBasePath value is a unicode string, which redirects Windows to load the local hosts file from the directory %windows%\help, instead of the normal location %windows%\System32\drivers\etc.

The trojan will also enumerate and modify every NameServer value found under
HKLM\SYSTEM\ControlSet001\Services\Tcpip\Parameters\Interfaces and HKLM\SYSTEM\ControlSet002\Services\Tcpip\Parameters\Interfaces
recursively to make sure that the DNS servers are set to 69.57.146.14 and 69.57.147.175 for every network interface present.

Next the trojan will modify the hosts file located in the %windows% directory so that the domain names of some popular search engines will resolve to the IP address 207.44.220.30.

The domain names are as follows:

www.google.akadns.net

If the trojan finds that the services file existed in %windows%\system32\drivers\etc, the hosts file will be placed inside the %windows%\help directory instead.

The trojan will finally create the file %windows%\winlog as a marker and will exit.

Re: Computer extremely slow - can you please help tell me what's wrong?
 

Have you tried running Adaware and Spybot? Make sure they are updated and then run them from safe mode. You can get to safe mode by pressing F8 when the computer starts to boot.

Re: Computer extremely slow - can you please help tell me what's wrong?
 

In addition to Ad-Aware and Spybot, please do the following:

Go to Windows Update and get the Critical Updates for your system

Get the latest version of HijackThis (currently 1.99.1)

Close all browser windows, scan with the updated hijackthis, post the new log.

Re: Computer extremely slow - can you please help tell me what's wrong?
 

You have a worm and a trojan. Reboot into safe mode following the instructions here and navigate to and delete the following:

C:\WINDOWS\SVCHOST.EXE
C:\WINDOWS\smss.exe

Reboot normally after doing the above, rescan with hijackthis, then post that log here please.
