Hi Linitchka, welcome to DaniWeb :)
1. You said that you've tried some solutions already; please tell us exactly what you've tried.
2. For the sites that you can't access:
* What error message/error page do you get?
* Is it the main page of the sites that you cannot access, or is it only areas/pages within the sites that need to be accessed with a username/password (that is, secure pages)?
3. Your log shows the remains of at least one malware infection; please do the following:
You will need to close/quit all web browser programs and disconnect from the Internet for much of the following, so you should print out these instructions or save them into a text file with Notepad.
* Download and install the following utilities:
Windows Defender - http://www.microsoft.com/downloads/details.aspx?FamilyID=435bfce7-da2b-4a6a-afa4-f7f14e605a0d&displaylang=en
CCleaner - www.ccleaner.com
ewido Anti-malware - http://www.ewido.net/en/download/
When installing ewido, under "Additional Options" uncheck..Install background guard
Install scan via context menu
Launch ewido, there should be an icon on your desktop, double-click it.
The program will now open to the main screen.
When you run ewido for the first time, you may get a warning "Database could not be found!". Click OK. We will fix this in a moment.
You will need to update ewido to the latest definition files.On the left hand side of the main screen click update.
Then click on Start Update.
The update will start and a progress bar will show the updates being installed.
(the status bar at the bottom will display ("Update successful" )
If you are having problems with the updater, you can use this link to manually update ewido.
ewido manual updates
Don't run a scan with ewido yet; just close the program once the updates are installed.
* Open McAfee and check for/install the most current updates. Again- don't run a scan with McAfee; just close the program once the updates are installed.
* Close all open programs, especially Internet Explorer.
* Run HijackThis again, put a check mark in the boxes to the left of the following entry, and then click the "Fix checked" button. Close HJT after the fix is complete:
O2 - BHO: BHObj Class - {00000010-6F7D-442C-93E3-4A4827C2E4C8} - D:\WINDOWS\nem220.dll (file missing)
* Reboot into safe mode (you get to the safe mode boot option by hitting the F8 key as your computer is starting up) and:
* Open Windows Explorer, and in the Folder Options->View settings under the Tools menu, select "show hidden files and folders", and uncheck "Hide protected operating system files" and "Hide extentions for known file types".
* Run CCleaner.
- Go to Options-> Advanced: Uncheck "Only delete files in Windows Temp folders older than 48 hours"
- Go to Options>CustomFolders>Add Folder>Navigate to these folders (click on bold file once and hit OK) :
* C:\Windows\Temp
* C:\Windows\Prefetch
* C:\Documents and Settings\\Local Settings\Temporary Internet Files\ (This will delete all your cached internet content including cookies.)
* C:\Documents and Settings\\Local Settings\Temp
* C:\Documents and Settings\\Local Settings\Temporary Internet Files
* C:\Documents and Settings\\Local Settings\Temp
* C:\Documents and Settings\\Cookies
* C:\Documents and Settings\\Cookies
Hit OK
- In left pane, scroll down to "Advanced, Custom Folders", put a check in Custom Folders
- Click on Run Cleaner. It may take a while for the program to perform its cleaning, so be patient. Close the program when it has finished.
* Run McAfee, Windows Defender, and ewido; have the programs fix all malicious items they find.
When ewido finds the first malicious object on your system, it will ask you if it should clean it. When it asks this, put a checkmark in the lower left corner of the box that says "Perform action on all infections", then choose clean and click OK.
Save the log file that ewido will create after it finishes scanning; you'll be including that log in your next post here.
* Open Windows Explorer again, look for the following file, and delete it if it still exists:
D:\WINDOWS\nem220.dll
* Empty your Recycle Bin, reboot normally, run HijackThis again, and post the new log. Also post the log that ewido generated.
