Hi, I'm new here and a computer novice so please be nice! Basically about two weeks ago Norton 360 Download Insight said I had been infected with 6 different types of -I think- trojans. They were called JS.Alescurf. Can someone tell me what this actually is? Is it a trojan, virus, spyware? Any idea where or how I could have got this particular infection from? I have a clean surfing history, only thing was I downloaded 5 files for the first time ever from a site I triple checked before and after that my friends use with no problems (a youtube converter). If this was the cause, why did Norton take about 4 hours to detect them? Also, I downloaded 5 files, yet I got 6 infections?! After googling, some sites say this is actually something that you get from visiting a website? Anyway, Norton said it got rid of them, I was still unconvinced and went to someone, who downloaded Combofix from your site, after downloading malwarebytes showed nothing. Combofix said it was safe, so I was ok with that. However, I've found now that I can't use Internet Explorer, because every time I go to any website I get a pop-up saying the same thing- 'You are about to view pages over a secure connection, anything you view cannot be viewed by others over the web' or something similar. This is to pages that aren't even an https page, like a local news site. I checked my Internet options and privacy settings and they're normal. So I use chrome, except I've found that sometimes the computer screen flashes when I do stuff like watch YouTube, as if someone's taking a screenshot. Also, loading websites that were normally quite fast takes longer because chrome says 'waiting for ***.com' -some ad site like a twola. However, I have no redirections or bad pop ups etc, chrome surfing is basically normal apart from the stated issues. Basically, at this moment in time I'd rather someone could tell me what's actually going on rather than telling me to download more stuff. Any information about what the infection is, what is does, where I get it from, the reason why my screen flashes and why I can't use Internet Explorer would be really appreciated!!!!!!!! Thank you!!!

Information about my computer:
Windows 7 Operating System
Use Norton 360
Used to use Internet Explorer, now use Chrome due to above problem
Examples of the infection-
custom[1].js (JS.Alescurf).
Website I was on when Norton reported the infections: uniplanet.com
Website used to download files: youtubeconverter to mp3 site.

If you want me to provide any more information I'd be happy to!! Thank you!!!!!!!!

Hi,

After performing these scans, enter the results in your next post and also update me on the status of the PC.

Note: You may have to perform some or all of the following in Safe Mode With Networking, depending on if you have internet access while in the normal Windows environment.

================================================================================

Download Security Check by screen317 from here or here.
  • Save it to your Desktop.
  • Double click SecurityCheck.exe and follow the onscreen instructions inside of the black box.
  • A Notepad document should open automatically called checkup.txt; please post the contents of that document.

================================================================================

Please download MiniToolBox and run it.

Checkmark following boxes:
  • Report IE Proxy Settings
  • Report FF Proxy Settings
  • List content of Hosts
  • List IP configuration
  • List Winsock Entries
  • List last 10 Event Viewer log
  • List Installed Programs
  • List Users, Partitions and Memory size
Click Go and post the result.

================================================================================

Please download and scan with SUPERAntiSpyware Free
  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If it will not start, go to Start > All Prgrams > SUPERAntiSpyware and click on Alternate Start.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the "General and Startup" tab, and under Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Click the "Scanning Control" tab, and 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 a scan just yet.
Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with SUPERAntiSpyware as follows:
  • Launch the program and back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan and click "Next".
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • 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.
    • If there are several logs, click the current dated log and press View log. A text file will open in your default text editor.
    • Please copy and paste the Scan Log results in your next reply.
  • Click Close to exit the program.
If you have a problem downloading, installing or getting SAS to run, try downloading and using the SUPERAntiSpyware Portable Scanner instead. Save the randomly named file (i.e. SAS_1710895.COM) to a usb drive or CD and transfer to the infected computer. Then double-click on it to launch and scan. The file is randomly named to help keep malware from blocking the scanner.

================================================================================

Please download Malwarebytes Anti-Malware and save it to your desktop.
  • Important!! When you save the mbam-setup file, rename it to something random (such as 123abc.exe) before beginning the download.
Malwarebytes 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 and double-click on the renamed file to install the application.
    For instructions with screenshots, please refer to this Guide.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • Malwarebytes 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 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.
  • Under the Scanner tab, make sure the "Perform Quick Scan" option is selected.
  • Click on the Scan button.
  • When 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, then click the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked and then 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.
  • 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 the database version and your operating system.
  • Exit Malwarebytes when done.
Note: If Malwarebytes encounters a file that is difficult to remove, you will be asked to reboot your computer so it can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally will prevent Malwarebytes from removing all the malware.

================================================================================

Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

    Posted Image
  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.
-- If you encounter any problems, try running GMER in safe mode.
-- If GMER crashes or keeps resulting in a BSODs, uncheck Devices on the right side before scanning

Hi, thanks so much for your quick and detailed reply. Before I download anything I was hoping to actually get some information as to what has caused the problems in the first place and what the infection actually does, it would seem pointless to me to download more software if my computer isn't actually infected, but has problems with internet explorer etc.. Do you know anything about the type of infection that it is/ what it does/ where it comes from? Again, thanks for your fast reply, hope I can finally see the back of this infection.
