Hi Trevuren,

I did everything mentioned in the article, and it seemed that KAV has cleaned some of the viruses, and I saved an HJT log BUT I lost my internet explorer (it opens for few seconds and closes by itself). And the system is too slow now, specially when I reboot it. What should I do?

Note: NAAV I enabled real time protection against networks attacks before reconnecting to the internet to avoid more viruses.

I am sending this from another computer.

WE GOT IT JUJU

Please print out or copy this page to Notepad. Make sure to work through the fixes in the exact order in which they are mentioned below. If there's anything that you don't understand, ask your question(s) before proceeding with the fixes.

First we need to make all files and folders VISIBLE:

Go to start>control panel>folder options>view (tab)
*choose to "show hidden files and folders,"
*uncheck the "hide protected operating system files" and the "hide extensions for know file types" boxes.
*Close the window with ok
*All hidden files will now be visible

Please RUN HijackThis.
. Click the SCAN button to produce a log.

Place a check mark beside each one of the following items:

R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Bar = http://g.msn.com/0SEENUS/SAOS01
O18 - Filter: text/html - (no CLSID) - (no file)


Now with all the items selected, and all windows closed except for HJT, delete them by clicking the FIX checked button. Close the HijackThis window and Reboot Your System

Finally, RUN Hijackthis again and produce a new HJT log. Post it in the forum so we can check how everytjhing for final review.

Regards,

Trevuren

Congratulations, your log shows that your SYSTEM IS CLEAN

There are a few things you must do once you are completely clean:

1. Reset and Re-enable your System Restore to remove bad files from the backup that Windows makes as no program is able to clean those files:

TO DISABLE SYSTEM RESTORE
1. Right-click "My Computer", and then left click "Properties".
2. Left click on "System Restore Tab"
3. Check box beside "Turn Off System Restore"
4. Left click on "Apply"

TO ENABLE SYSTEM RESTORE
1.Remove check mark from "Turn Off System Restore"
2.Click on "Apply"

2. Cleanup the leftovers. Download CleanUP! - Cleans temporary files from IE and Windows, empties the recycle bin and more. Great tool to help speed up your computer and knock out those nasties that like to reside in the temp folders.


3. Finally, Re-hide your System Files and Folders to prevent any future accidents.


Here are some tips to reduce the potential for spyware infection in the future:

Make sure you keep your Windows OS current by visiting Windows update
regularly to download and install any critical updates and service packs. With out these you are leaving the backdoor open.

I strongly recommend installing the following applications:
  • Spywareblaster <= SpywareBlaster will prevent spyware from being installed.
  • Spywareguard <= SpywareGuard offers realtime protection from spyware installation attempts.
  • How to use Ad-Aware to remove Spyware <= If you suspect that you have spyware installed on your computer, here are instructions on how to download, install and then use Ad-Aware.
  • How to use Spybot to remove Spyware <= If you suspect that you have spyware installed on your computer, here are instructions on how to download, install and then use Spybot. Similar to Ad-Aware, I strongly recommend both to catch most spyware.
To protect yourself further:
  • Spyad <= IE/Spyad places over 4000 websites and domains in the IE Restricted list which will severely impair attempts to infect your system. It basically prevents any downloads (Cookies etc) from the sites listed, although you will still be able to connect to the sites.
  • MVPS Hosts file <= The MVPS Hosts file replaces your current HOSTS file with one containing well know ad sites etc. Basically, this prevents your coputer from connecting to those sites by redirecting them to 127.0.0.1 which is your local computer
  • Google Toolbar <= Get the free google toolbar to help stop pop up windows.
And also see TonyKlein's good advice
So how did I get infected in the first place? (My Favorite)

Regards,

Trevuren
