How to Remove the Trojan Startpage.4.A0 Spyware/Virus (Internet Browser Hijacker)
(From Windows 98/98SE/Me)
Symptoms
Startpage.4.A0 (SP4A) re-directs your browser startpage to a non-identifiable web search page. Attempts to reset your default web page fail repeatedly. The Trojan continues to reset your startpage. The Trojan does this by continuing to copy a series of xxxx.dll files into your Windows/System folder - these files are detected by most virus checkers and can be deleted manually. However, deleting the xxxx.dll files will not solve the problem as the SP4A Trojan will continue to generate randomly named xxxx.dll files in the Windows/System folder. These xxxx.dll files are loaded each time you start your browser and reset the startpage to the undesired search page.
Another test that can be performed to see if you have the SP4A Trojan is to run the Windows games "Freecell" and "Solitaire". If you have the Trojan on your system, "Freecell" will normally fail to run and "Solitaire" may start but display garbled letters in the title box and will then freeze.
Steps to Remove the Startpage.4.A0 Trojan
1) Download
http://download.broadbandmedic.com/HostsFileReader.exe. Run the program and click on the "Scan for Hosts" button. Any host files found on your system will be listed in the bottom window. Select any host files found and press the "Reset Default" button. Exit from the program.
2) Download "Startdreck" Version 2.1.5 from
http://www.niksoft.at/download/startdreck.htm. Unzip to it's own
folder.
3) Download "Win98fix.zip" from
http://www10.brinkster.com/expl0iter...ast/pvtool.htm. Unzip to it's own folder.
Note: If the above links should fail, simply run an internet search with your favourite search engine and you should be able to locate the files. You can also copy and paste the above links into your web browser.
4) Run "StartDreck.exe". Press "Config" and "Unmark All". Check these boxes only: "Registry - Run Keys" and System/Drivers - Running Processes". Press "OK".
In the on-screen log that is generated, look under the section "Local Machine, RunServicesOnce" for a line that is similar to:
aaaa=rundll32 C:/WINDOWS/SYSTEM/xxxxxx.dll, StreamingDeviceSetup.
"aaaa" will any random alphabetic letters and "xxxxxx.dll" will be the name of the offending SP4A Trojan file that must be removed. Note the name of the file as it appears for your system. Mine was "winenh.dll". However, this file will not yet be visible in the Windows/System folder - even though you may have the folder view setting "show hidden files" turned on.
5) Go to the "Win98fix" folder created in Step 3 above. Find the "RunFix.reg" file. Single (or double click) on the file to bring up the "Registry Editor" box - click "Yes" to merge the file with your Windows registry file.
6) Restart your computer/Windows.
7) After system reboot, the offending "xxxxxx.dll"file will now be visible in the Windows/System folder. Delete the "xxxxxx.dll" file and the SP4A Trojan will be deleted from your system.
8) Test to see that the Trojan has been removed by running "Freecell" and "Solitaire" - they should now function normally.
