seeking filost removal advice

[scriblerus]

Hello. This is my first time posting and I'm stuck with a filost 540 problem.

When I open my browser another window sometimes opens redirecting me to a random site. It's a bit annoying and I'm worried it might be harmful somehow.

Anyway, below is a hjt log. Any help would be much much appreciated.

Cheers.

Hi Howard,

I followed your instructions. There were only two files I couldn't remove:

C:\WINDOWS\SYSTEM32\AsntDll.dll
C:\WINDOWS\pchealth\BBJ.exe

AsntDll.dll was in use or otherwise unable to delete.
BBJ.exe I couldn't find that file.

Here's the new HJT log.

Thanks a bunch for the response.

The C:\WINDOWS\pchealth\BBJ.exe file is gone, so nothing to worry about there.

As for C:\WINDOWS\SYSTEM32\AsntDll.dll do the following.

Run HJT and click on the config button, then the misc tools button. Click on the delete file on reboot button and browse to C:\WINDOWS\SYSTEM32\AsntDll.dll.

Click on the AsntDll.dll file and click open. You will be prompted to restart your computer, click yes.

Once your computer has restarted the AsntDll.dll should have been deleted.

Please post a fresh HJT log.

Regards Howard
