Hello:
My anti-virus software, which is provided by SBC uses Computer Associates for the detection. I do not know what type of program it uses because it only comes on a SBC. It detects a Win32.Coreflood virus. The file name it gives for the virus is afupd2.exe and its location is C:\DOCUME~1\LP\LOCALS~1\Temp\
I have run Adaware, Spybot and Spyware Doctor with no luck in finding the actual file that is causing the problem. I have deleted temporary internet files and temporary files without success. The adupd2.exe keeps regenerating even after the virus detector finds it and deletes it.

Can you help?

Thanks!
:thumbsup:

I do not really see much wrong with this log. It is possible that the AV software found and removed that virus.

This process will clean out your Temp files and your Temporary Internet Files. Please do both steps:

Step 1:Delete Temp Files
To clean out your temp files, click on Start and then run, and type %temp% and press the ok button.

This should open up the temp directory that your machine uses. Please delete all files that are found there. If you get an error when deleting a file, skip that file and delete all the others. If you had trouble deleting a file, reboot into Safe Mode and follow this step again. You should now be able to delete all the files.

Step 2: Delete Temporary Internet Files
Now I want you to open up Internet Explorer, and click on the Tools menu and then Internet Options. At the General tab, which should be the first tab you are currently on, click on the Delete Files button and put a checkmark in Delete offline content. Then press the OK button. This may take quite a while, so do not be alarmed with how long it takes. When it is done, your Temporary Internet Files will now be deleted.

If some files do not delete, then reboot into safe mode and try the above steps again.

Print out these instructions and then close all windows including Internet Explorer.

Then I want you to fix some of those entries. Please do the following:

Please make sure that you can view all hidden files. Instructions on how to do this can be found here:

How to see hidden files in Windows

Run Hijackthis again, click scan, and Put a checkmark next to each of these. Then click the Fix button:

R3 - Default URLSearchHook is missing
O4 - HKCU\..\Run: [Microsoft Works Update Detection] ? ??????\WkDetect.exe

Reboot your computer and post a new log.

Hello:

The afupd2.exe tries to regenerate whenever I go online. Other than that the virus scanner doesn’t detect it. I used Trend Micro's Online Scan, which found C:\windows\wsaupd.exehttp I deleted the file with the Trend Micro scanner but the afupd2.exe keeps regenerating.

Here is the new log.

Hello,

I'm sorry but what file do you mean? Do you mean the afupd2.exe because my virus scanner deletes it whenever it reappears and the C:\windows\wsaupd.exehttp was deleted by Trend Micro's Online Scan. So I don't know what file is causing the problem now. afupd2.exe only seems to reappear when I go online so I am assuming that Internet Explorer is involved some how. I can't recall but would reinstalling Windows fix the problem but I don't mean a full and complete reformat that would lose everything on the hard drive.

:thumbsup:
Sorry
