My wife and I have two computers in the house. My computer is connected directly to the net by an ADSL broadband modem. A transmitting router is also attached to this modem which allows my wife's computer to connect to the net via a wireless modem in the next room.
The last week or so I've noticed a considerable slowdown in our internet connection, and I'm not sure what's causing the problem. I've scanned my box with malwarebyte's, and partially with avast, and not found anything of note yet. I scanned my wife's computer with the same tools: avast found PCFriendly\inuninst and adware.gen [adw]; Malwarebytes found 7 instances of adware.minibug.
I'd like to make sure in particular that our internet connection isn't being somehow hijacked. Starting with my wife's computer first, here is the hijackthis log:

We both usually use firefox, but I'm posting this from my wife's computer and firefox appears to be hijacked to such an extent that it's virtually unusable, so I've switched to IE for the time being.
Could someone take a look at the log and see if there's anything fishy going on?
Stay with this topic until I give you the all clean post.
You might want to print these instructions out.
I suggest you do this:
You need To disable TeaTimer, it can stop our fix.
The best way is to do both, Right click the system tray icon and shut down. This will reset TT's registry snapshot. Then, open spybot in advanced mode and turn it off. When cleaning is done, open Spybot in advanced mode to turn back on. Once fix is completed in the all clear post!!
Please do not delete anything unless instructed to.
Double-click ATF-Cleaner.exe to run the program.
Under Main choose: Select All
Click the Empty Selected button.
(If you use FireFox or the Opera browser
To keep saved passwords, click No at the prompt.)
It's normal after running ATF cleaner that the PC will be slower to boot the first time.
Next:
Download ComboFix from Here or Here to your Desktop. **Note: In the event you already have Combofix, please delete it from your desktop and download this new version . It is important that it is saved directly to your desktop**
——————————————————————–
Close any open browsers and make sure you are disconnected from the net. Unplug the cable if need be before running combofix.
WARNING: IF you have not already done so Combofix will disconnect your machine from the Internet when it starts
Please do not re-connect your machine back to the Internet until Combofix has completely finished.
——————————————————————–
Double click on combofix.exe & follow the prompts.
When finished, it will produce a report for you.
Please post the "C:\ComboFix.txt" along with a new HijackThis log for further review
****Note: Do not mouseclick combofix's window while it's running. That may cause it to stall or freeze ****
*If there is no internet connection when Combofix has completely finished then restart your computer to restore back the connections.
Give it atleast 20-30 minutes to finish if needed.
Good evening, Mr. (Mrs.?) Tate, and greetings once again from the Great White North. I don't know if you remember, but you helped me once not too long ago with a friend's computer.
Here are your logs. First, Combofix:
ComboFix 08-09-20.05 - Marita 2008-09-23 17:27:25.1 - FAT32x86
Microsoft Windows XP Home Edition 5.1.2600.2.1252.1.1053.18.29 [GMT 2:00]
Running from: C:\Documents and Settings\[removed]\Start-meny\Skrivbord\ComboFix.exe
* Created a new restore point
WARNING -THIS MACHINE DOES NOT HAVE THE RECOVERY CONSOLE INSTALLED !!
.
((((((((((((((((((((((((((((((((((((((( Other Deletions )))))))))))))))))))))))))))))))))))))))))))))))))
.
C:\WINDOWS\system32\autorun.ini
.
((((((((((((((((((((((((( Files Created from 2008-08-23 to 2008-09-23 )))))))))))))))))))))))))))))))
.
It completed the scan very quickly: maybe five minutes, max.
Here's the subsequent HijackThisLog:

Now type Combofix /u in the runbox and click OK. Note the space between the X and the U, it needs to be there.

Here's my usual all clean post
Log looks good
Make your Internet Explorer more secure - This can be done by following these simple instructions:
From within Internet Explorer click on the Tools menu and then click on Options.
Click once on the Security tab
Click once on the Internet icon so it becomes highlighted.
Click once on the Custom Level button.
Change the Download signed ActiveX controls to Prompt
Change the Download unsigned ActiveX controls to Disable
Change the Initialize and script ActiveX controls not marked as safe to Disable
Change the Installation of desktop items to Prompt
Change the Launching programs and files in an IFRAME to Prompt
Change the Navigate sub-frames across different domains to Prompt
When all these settings have been made, click on the OK button.
If it prompts you as to whether or not you want to save the settings, press the Yes button.
Next press the Apply button and then the OK to exit the Internet Properties page.
Update your AntiVirus Software - It is imperative that you update your Antivirus software at least once a week
(Even more if you wish). If you do not update your antivirus software then it will not be able to catch any of the new variants that may come out.
Use a Firewall - I can not stress how important it is that you use a Firewall on your computer.
Without a firewall your computer is succeptible to being hacked and taken over.
I am very serious about this and see it happen almost every day with my clients.
Simply using a Firewall in its default configuration can lower your risk greatly.
For a tutorial on Firewalls and a listing of some available ones see the link below:
Note: I no longer suggest Zone Alarm
Understanding and Using Firewalls
Visit Microsoft's Windows Update Site Frequently - It is important that you visit http://www.windowsupdate.com regularly.
This will ensure your computer has always the latest security updates available installed on your computer.
If there are new updates to install, install them immediately, reboot your computer, and revisit the site
until there are no more critical updates.
MVPS Hosts file replaces your current HOSTS file with one containing well known ad sites and other bad sites. Basically, this prevents your computer from connecting to those sites by redirecting them to 127.0.0.1 which is your local computer, meaning it will be difficult to infect yourself in the future.
Update all these programs regularly - Make sure you update all the programs I have listed regularly.
Without regular updates you WILL NOT be protected when new malicious programs are released.
Only run one Anti-Virus and Firewall program.
I would also suggest you read this:
So how did I get infected in the first place?
