Hi greenvillage47,

  1. Get this version of Hijackthis from http://danborg.org/spy/hjt/alternativ.exe

2 Save it in a permanent folder of your choice, such as C:\HJT. To create this specific folder on your hard drive:
Double click the ‘My Computer’ icon on your desktop, then under the category hard disk drives: double click Local Disk:,
then select file->New → Folder and name it HJT
3 Run hijackthis. (alternativ exe).

Choose the “Do a system scan and save a log file” option to perform your scan.
HijackThis will analyze your system, and automatically open a notepad textfile
containing the HijackThis log when the scan is finished.
Open the text files containing the logs with a text editor and click Edit → Select All, followed by Edit → Copy.
From within the browser window and with the message body text box selected, click Edit → Paste.
Post hijackthis log here, if the folder is large use two postings for it.
After we here have evaluated this hjt-log we can do the following, but don’t do this yet!
