Hello

This is my first post here.

I have Norton 360 security and for a while whenever browsing the internet intrusion attempts would come up like clockwork every few minutes. The report said the severity was high. It shows me the attacking IP adress and target and some other stuff. It has stopped doing this for the most part now however it still comes every now and then. Another thing which started happening very recently (more recently than intrusion attempst started) when i search something on google it will redirect me to another site. Usually it is askjeeves or a similar site with what i posted in google entereed into it. It seems to go through phases of doing this and not doing this. One other thing is my moms email sent out emails to every one of her contacts about viagra or something like that.

Are these linked? How do I stop these from happening?

I looked up on the internet about trying to stop this repeated intrusion attempts thing and found some different answers. I noticed on one it said run "combofix". I decided to download it however before you download it says

"IMPORTANT : ComboFix is extremely powerful , You should not run ComboFix.exe unless you are asked to by a trained helper"

So I am looking for a helper who knows what they are doing. I am a complete computer idiot by the way


I've just looked again, there are a number of "Application paths" shown by Norton in security history. I dont know if this will help diagnose the problems but her they are:

- Severity: High, gives IP adress, apllication path:DEVICE/HARDDISKVOLUME1/WINDOWS/SYSTEM32/SCVHOST.EXE
- Severity: High, gives IP, application path: DEVICE/HARDDISKVOLUME1/PROGRAM FILES/INTERNET EXPLORER/IEXPLORE.EXE
- Severity: Medium, no IP "unauthorized access blocked (Open Process Tool)


I'd much appreciate any help

thanks

Is this PC on a network?

Run a full system scan in safe mode with the latest Norton definitions. Then unplug the network connection and reboot the computer. Does the backdoor.tidserv detection come up again? If so, then we need to search for another undetected process on your computer.


Now run TDDS Killer
Please download the TDSS Rootkit Removing Tool (TDSSKiller.exe) and save it to your Desktop. <-Important!!!
Be sure to download TDSSKiller.exe (v2.4.0.0) from Kaspersky's website and not TDSSKiller.zip which appears to be an older version 2.3.2.2 of the tool.
  • Double-click on TDSSKiller.exe to run the tool for known TDSS variants.
    Vista/Windows 7 users right-click and select Run As Administrator.
  • If TDSSKiller does not run, try renaming it.
  • To do this, right-click on TDSSKiller.exe, select Rename and give it a random name with the .com file extension (i.e. 123abc.com). If you do not see the file extension, please refer to How to change the file extension.
  • Click the Start Scan button.
  • Do not use the computer during the scan
  • If the scan completes with nothing found, click Close to exit.
  • If malicious objects are found, they will show in the Scan results - Select action for found objects and offer three options.
  • Ensure Cure (default) is selected, then click Continue > Reboot now to finish the cleaning process.
  • A log file named TDSSKiller_version_date_time_log.txt (i.e. TDSSKiller.2.4.0.0_27.07.2010_09.o7.26_log.txt) will be created and saved to the root directory (usually Local Disk C:).
  • Copy and paste the contents of that file in your next reply.


Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware (v1.46) and save it to your desktop.alternate download link 1
alternate download link 2
MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • 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.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.
