Hi

I'm not very tech so excuse me if I dont use the right 'language'!

My AVG resident shield is telling me its found the win32/Heur virus..... but its in a utility file called "soft stylus" which I thought was one of the original pre-loaded files that lets us do clever touch screen stuff on the PC. Theres nothing else going wrong with my PC. Surely AVG is wrong???

Confused x

Hi,I am seeing a bit of conflicting info on this. It may be a false positive. Did AVG quarantine the file??

in the meantime let's run this.

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.

AVG hasn't quarenteend the files, its pu them up on the scan results page, saying that i am 'infected' & now is giving me the option to 'remove all healed'. I havent done anything with them yet. PC is still running smoothly. I am now going to try your Malwarebytes suggestion.......

Well well! The Malwarebytes quickscan didnt pick up anything, so i ran a full scan. Here are the results:

I cant figure out how to copy a screenshot to this page but basically my AVG still shows the following;

Scan Results
Infections
File Infection Result
D:\Utility\SoftStylus\2_2_115\Data1.cab:\Stylus.exe virus found Win32/Heur Infected
D:\Utility\SoftStylus\2_2_115\Dta1.cab virus found Win32/Heur Infected
C:\Program Files\SoftStylus\Stylus.exe virus found Win32/Heur Infected

View Details Remove Selected Remove all unhealed


AVG has moved the C:\Program... one to the virus vault. It hasnt done anything with the other two files The 'soft stylus' is the pen you get with a touchscreen PC so you can see why I've hesitated to remove these files. My pc seems to be running fine. The AVG Resident Shield keeps popping up to tell me about this 'threat'. I read about AVG's false positives on a forum whilst checking the validity of this one out. I've downloaded AVG's most recent updates.It didnt change anything.

Obviously Malwarebytes found nothing so what do i do now please?? xx

Hello,This is possibly a False positive. We should double check it before we take action.

Lets' upload this file for a second opinion on what it actually is.. The one in the quarantine.

Please make sure that you can view all hidden files. Instructions on how to do this can be found here:
How to see hidden files in Windows

Please click this link-->Jotti

When the jotti page has finished loading, click the Browse button and navigate to the following file and click Submit.
<filepath>suspect.file

Please post back the results of the scan in your next post.

If Jotti is busy, try the same at Virustotal: http://www.virustotal.com/


NOTE:
For submission to a specific anti-virus vendor see Submitting Virus Samples: How to Submit a Virus.
You may want to send it to AVG also.
