Yesterday I was using my computer and I saw a virus alert from my AVG8 software, saying I have a 'Trojan horse SHeur2.hsf' in my computer. After that, my firewall closed itself and so did my windows automatic updates. I managed to set my firewall back on, but for some reason, I could not set my updates back to 'automatic/on'. Later I looked the virus up on Google and read several articles saying that it was a false alarm. I shut my computer down afterwards, feeling better.

Later when I got back on the computer, I ran a scan with AVG8, and the results were: 2 infections found. 2 infected objects removed/healed. 4 warnings.
The two infections were: Trojan horse Downloader.Generic8.HPC, and a registry key in relation to the virus.
The warnings: Tracking cookies. Though, last time I scanned there were only two, now there are four...but I don't know if they have any relation to the virus.

AVG has put the file in a virus vault, but I'm not sure what will happen next, because I've seen people say that it doesn't work. And I'm getting a lot of pop ups all of a sudden.

Is it possible that I'm still infected?

Hi,

Yes it's possible you're still infected.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2
  • Make sure you are connected to the Internet.
  • Double-click on Download_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 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 and you may be prompted to restart your computer. (see Note below)
  • 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 and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts. Click OK to either and let MBAM proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot will prevent MBAM from removing all the malware.

Never mind. My computer was reformatted.

I wasn't able to open the mbam installer though.

Sorry to hear about having to reformat but sometimes that is the best solution. In some instances an infection may have caused so much damage to your system that it cannot be completely cleaned or repaired. The malware may leave so many remnants behind that security tools cannot find them. Starting over by wiping your drive, reformatting, and performing a clean install of the OS removes everything and is the safest action.

Tips to protect yourself against malware and reduce the potential for re-infection:
• "Simple and easy ways to keep your computer safe".
• "How did I get infected?, With steps so it does not happen again!".
• "Hardening Windows Security - Part 1 & Part 2".
• "IE Recommended Minimal Security Settings" - "How to Secure Your Web Browser".
• "Use Task Manager to close pop-up messages to safely exit malware attacks"

• Avoid gaming sites, underground web pages, pirated software, crack sites, and peer-to-peer (P2P) file sharing programs. They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and Flash ads that install viruses, Trojans and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users. The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications. Read P2P Software User Advisories and Risks of File-Sharing Technology.
