HijackThis Log Analyse - Multiple Web Vulnerabilities



Release Date:
=============
2011-07-22


Vulnerability Laboratory ID (VL-ID):
====================================
107


Product & Service Introduction:
===============================
HijackThis opens you a possibility to find and fix nasty entries on your computer easier.
Therefore it will scan special parts in the registry and on your harddisk and compare them with the default settings. 
If there is some abnormality detected on your computer HijackThis will save them into a logfile. In order to find out what 
entries are nasty and what are installed by the user, you need some background information. A logfile is not so easy to analyze. 
Even for an advanced computer user. With the help of this automatic analyzer you are able to get some additional support. Just 
paste your complete logfile into the textbox at the bottom of this page. Due to a few misunderstandings, I just want to make it 
clear that this site provides only an online analysis, and not HijackThis the program.
