So yesterday I downloaded a torrent, and, stupidly, when I went to watch the video after I'd downloaded it, it told me I had to download something to get it to work, so I did. My Firefox browser then opened a bunch of different tabs, and then the computer got a blue screen involving "IRQL_NOT_LESS_OR_EQUAL." It then restarted, and when I tried to log in again, the same same blue screen came up and crashed the computer again.

It then started to work the next time I logged in, but my Norton Anti-Virus kept telling me that I was being attacked, from something originating in "firefox.exe", and that it had been blocked from doing so. I then uninstalled Firefox and installed Google Chrome, but Norton kept telling me I was being attacked. The difference is that this time I was being attacked by "svchost.exe". I have attached a picture of the message Norton sent me.

So now whenever I log on, I keep getting these same messages from Norton, and every so often, when I go on the internet, Norton tells me that whatever browser I am using at the time, its .exe file is also attacking my computer.

I also got an error report type thing that told me what happened during the last crash:

"Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7600.2.0.0.768.3
Locale ID: 4105

Additional information about the problem:
BCCode: a
BCP1: 0000000000000040
BCP2: 0000000000000002
BCP3: 0000000000000001
BCP4: FFFFF80002C79CD8
OS Version: 6_1_7600
Service Pack: 0_0
Product: 768_1

Files that help describe the problem:
C:\Windows\Minidump\012911-33758-01.dmp
C:\Users\Alex\AppData\Local\Temp\WER-85987-0.sysdata.xm"

Anyway, any help is appreciated! I'd love to get this problem sorted out ASAP because I'm a University student with midterms and homework coming up.... what a great time for this to happen!

EDIT: [Regarding the picture I posted]

I have gotten other notifications recently from Norton saying that I was attacked by svchost.exe. The notifications change each time, though, as each time the "Attacking Computer" changes. I will keep an updated list of the computers that attack mine through svchost.exe below. I have not been recording the addresses of the computers yet, but I will now start.

-cap01tchaa.com, IP Address: (93.114.40.221, 443)
-u101mnay2k.com, IP Address: (93.114.40.221, 443)
-kur1k0nona.com, IP Address: (68.168.212.21, 443)
-lo4undreyk.com, IP Address: (68.168.212.18, 443)
-sh01cilewk.com, IP Address: (68.168.212.19, 443)

NOTE: I was only able to upload 4/5 pics that show the different attackers



EDIT 2: PROBLEM SOLVED!

After reading what the threat was (HTTPS Tidserv Request 2), I Googled it and found the solution to my problem. If anyone else has this problem, here is a link to the remover I used:

Hello thanks, I moved this from Windows 7 to the Am I Infected forum.

As this may also have other malware with Please run MBAM also.

Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware and save it to your desktop.
Download Link 1
Download Link 2MBAM 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.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • 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.
