I recently started to notice this problem a day or two ago. I was online and heard a few clicking sounds like a website was just clicked on and started to load. So I opened up task manager and noticed iexplore.exe running under SYSTEM. Nothing was visible on my screen when it was loaded, though I could hear the ads/commercials. I terminated the process only to have it load up a few minutes later (it also loaded up firefox.exe under SYSTEM, but this only happened once).

After it appeared a second time, I loaded up Process Explorer and found that it was loading under svchost.exe with a weird command line. I ran a virus scan through NOD32 and found nothing. SpyBot SD and Malwarebytes both detected a few objects that I have cleaned since then. With the protection module from Malwarebytes running, I noticed several blocked ip connection attempts. It has helped prevent iexplore.exe from loading, though I believe that I am still infected. Any advice on how to permanently get rid of this annoyance would be appreciated.

I ran a GMER scan to detect any rootkits, but I believe it found nothing. As for my firewall, I currently have Comodo Firewall installed but it did nothing to prevent this attack. I'm also currently running an Ad-Aware scan, but I doubt it will help me.

And here is the image I took of Process Explorer. The first svchost.exe in the list is what caused this problem.

I guess I was wrong, it's starting to load up even with the protection module loaded. Also some of the other system processes look dodgy with their small memory usage. Any help would be appreciated.

Hello, I suggest you post the infected MBAM log then run these.

The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.

Next run ATF and SAS:
Note.. SAS doesn't open the registry hives for other user accounts on the system, so scans should be done from each user account.

Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

From your regular user account..
Download Attribune's ATF Cleaner and then SUPERAntiSpyware , Free Home Version. Save both to desktop ..
DO NOT run yet.
Open SUPER from icon and install and Update it
Under Scanner Options make sure the following are checked (leave all others unchecked):
Close browsers before scanning.
Scan for tracking cookies.
Terminate memory threats before quarantining
.
Click the "Close" button to leave the control center screen and exit the program. DO NOT run yet.

Now reboot into Safe Mode: How to enter safe mode(XP)
Using the F8 Method

Then press enter on your keyboard to boot into Safe Mode
.

Double-click ATF-Cleaner.exe to run the program.
Under Main "Select Files to Delete" choose: Select All.
Click the Empty Selected button.

.

NOW Scan with SUPER
Open from the desktop icon or the program Files list
On the left, make sure you check C:\Fixed Drive.
Perform a Complete scan. After scan,Verify they are all checked.
Click OK on the summary screen to quarantine all found items.
If asked if you want to reboot, click "Yes" and reboot normally.

To retrieve the removal information after reboot, launch SUPERAntispyware again.
Click Preferences, then click the Statistics/Logs tab.
Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
