The "header" of the log is the portion at the top. It looks similar to this:
Logfile of HijackThis v1.99.1 Scan saved at 12:55:56 PM, on 10/3/05 Platform: Windows 98 SE (Win9x 4.10.2222A) MSIE: Internet Explorer v6.00 SP1 (6.00.2800.1106) If this is not what you are asking, please clarify the question. |

Back To step one
I am really fustrated right now. It looked like things were getting better and then got some stuff from aim that a friend sent me and i wasnt paying attention or my lil sister got it from website for myspace. Now everytime I start my computer a different virus comes up. But my comp is still running pretty good. Except for the pop ups and the desktop icons that come up Such as Free xbox and such. And also i couldnt find those files to delete. Maybe i messed up on the hidden files thing. But when i tried to do the search i couldnt get it to search in hidden files. Here is my current hijack log

The error is because we have removed a malware file that is still trying to run at startup, the message should not show up any more when you have completed this fix.

Please print out or copy this page to Notepad in order to assist you when carrying out the following instructions.
Please follow Symantec’s Guide to clean out your Norton quarantine. Launch KillBox.exe & select the following options:
* Click the RED X button. * Click Yes at the Delete on Reboot prompt. * Click Yes at the 'Pending Operations prompt'. Online Scans Trend Micro™ Anti-Spyware for the Web Utility (by clicking the "Scan and Clean your PC" button).
I then need you to repeat the same procedure above again... using the TrendMicro tool. I need the log from the second scan/clean...NOT the first...as this will contain what’s left in the system. How is your system now? Are there any remaining problems? |

Your log appears to be clean. If you still have any problems let me know and we will work on diagnosing those through other means. If not, there are just a few more things to go through to finish this off and help prevent future infections. Please post one more time even if you have no problems so we can mark this thread as resolved.
Disabling the Viewing of Hidden and System Files
Setting a new Restore Point Go to Start >> Run - type control sysdm.cpl,,4 & press Enter.
Windows Update Make sure to get the latest updates for Windows and Internet Explorer at Microsoft Update Site. Prevention A good virus scanner is a necessity in today's computer environment. Many virus scanners include active components that protect you from infection without even running a scan. Some good free antivirus programs include: AVG Free Avast! Home Edition (Antivirus & Firewall) AntiVir A firewall is the first line of defense standing between the internet and your computer. Some good free firewalls are: Zone Alarm Outpost Tiny Personal Firewall Avast! Home Edition (Antivirus & Firewall) Adaware SE and Spybot SD are a pair of anti-spyware scanners that should be run every week or two. Although there is some overlap there are many pieces of malware that is caught by one of these and not the other, therefore it is recommended you use both to compliment each other. Spybot also contains two other useful pieces. The first is "Immunize", this helps protect your computer against known exploits. The second is "TeaTimer", with this feature enabled you will receive notifications of all changes to the registry such as programs adding themselves to start-up and you default search page being changed. Spyware Blaster is a powerful tool that prevents "drive-by" downloads and other unwanted installations. It also uses no system resources, run it once and you're all set. Spyware Guard Is a realtime protection engine to guard your computer from spyware. This program does for spyware what an antivirus program does for viruses. IE-Spyad is a program that only needs to be run once to protect you from many malicious sites. It adds domains of known adware companies into the Restricted List of Internet Explorer, preventing them from performing malicious actions on your PC. The MVPS HOSTS file is a file you can download and use to replace your regular hosts file. It prevents many sites from performing malicious actions by blocking the sites from ever being accessed. Together these programs form a powerful barrier between the Internet and your computer. However, all the programs stand alone and feel free to eliminate any you are not comfortable with. Any protection you add to your PC is better than no protection at all. Alternative Programs Here are some alternatives that are either less suceptible than others to malware or don't contain malware where similar programs do. Trillian or Miranda-IM - These are Malware free Instant Messenger programs which allow you to connect to multiple IM services in one program! (AOL, Yahoo, ICQ, IRC, MSN) Desktop Weather - Free taskbar weather program that is free, malware free, and resource light. Firefox - This is an increasingly popular alternate browser. Whilst Internet Explorer is not a bad browser, almost every exploit crafted is targeted to take advantage of an IE weakness. Sun's Java - It's much more secure than Microsoft's Java Virtual Machine. |
