Hello
does anyone know what to do with Trojano-312[Trj] which appears to be on my machine?
The full name Avast records it in quarantine as is,
'explorer.exe C:\temp\AWTMP\C30518265\27C8C0'
I scan with Ad-ware and every time I do my virus checker, Avast! finds this virus.
I tried deleting it, repairing it and quarantine, but it is always there!
It doesnít appear to have done anything, but I doubt Iíd know if it did. Iím not too clever at these things.
Any suggestions would be greatly appreciated.
Ian
update, I have found it a further 3 times in the same place, the number string is different every time. And found once in c:\temp

Turn off avast while you do this step:

Please run two online virus scans:

http://housecall.antivirus.com/
http://www.pandasoftware.com/activescan/

Then let us know if its working better and what the scans found.

Hello Grinler
I have done as you instructed, Panda initially found one infected file then the pc crashed-blue screen 'dumping physical memory' etc. So I have no idea what Panda did then.
I then scanned again with Ad-ware withavast! switched on, it pulled it up again and I quarantined it.
Did another scan with Panda, avast turned off and it showed as clean.
Scanned again with avast! on using Ad-ware and, again it found the Trojano
Very confused...............

According to the avast! quarantine chest it lists it as C:\temp\AAWTMP followed by 2 strings of numbers which are different each time.

Once it was found in C:\temp and is listed as WIN32:Trojano-312[Trj] in both places it was found, but again with different numbers strings.

Reboot into safe mode and do the following:

This process will clean out your Temp files and your Temporary Internet Files. Please do both steps:

Step 1:Delete Temp Files
To clean out your temp files, click on Start and then run, and type %temp% and press the ok button.

This should open up the temp directory that your machine uses. Please delete all files that are found there. If you get an error when deleting a file, skip that file and delete all the others. If you had trouble deleting a file, reboot into Safe Mode and follow this step again. You should now be able to delete all the files.

Step 2: Delete Temporary Internet Files
Now I want you to open up Internet Explorer, and click on the Tools menu and then Internet Options. At the General tab, which should be the first tab you are currently on, click on the Delete Files button and put a checkmark in Delete offline content. Then press the OK button. This may take quite a while, so do not be alarmed with how long it takes. When it is done, your Temporary Internet Files will now be deleted.

Hello Grinler,
I have done as you instructed and had no problems deleting files in the temp folder while in safe mode, the same for Internet Explorer.
I ran another scan with Ad-ware and avast! found it again!
The quarantine chest lists it as 'explorer exe C:\temp\AAWTMP\C326125\74A10 WIN32:Trojano-312[Trj]'

Log looks clean...great job!

Now that you are clean, please follow these simple steps in order to keep your computer clean and secure:
  • Disable and Enable System Restore. - If you are using Windows ME or XP then you should disable and reenable system restore to make sure there are no infected files found in a restore point.

    You can find instructions on how to enable and reenable system restore here:

    Managing Windows Millenium System Restore

    or

    Windows XP System Restore Guide

    Renable system restore with instructions from tutorial above

  • Make your Internet Explorer more secure - This can be done by following these simple instructions:
    • From within Internet Explorer click on the Tools menu and then click on Options.
    • Click once on the Security tab
    • Click once on the Internet icon so it becomes highlighted.
    • Click once on the Custom Level button.
      • Change the Download signed ActiveX controls to Prompt
      • Change the Download unsigned ActiveX controls to Disable
      • Change the Initialize and script ActiveX controls not marked as safe to Disable
      • Change the Installation of desktop items to Prompt
      • Change the Launching programs and files in an IFRAME to Prompt
      • Change the Navigate sub-frames across different domains to Prompt
      • When all these settings have been made, click on the OK button.
      • If it prompts you as to whether or not you want to save the settings, press the Yes button.
    • Next press the Apply button and then the OK to exit the Internet Properties page.
  • Use an AntiVirus Software - It is very important that your computer has an anti-virus software running on your machine. This alone can save you a lot of trouble with malware in the future.

    See this link for a listing of some online & their stand-alone antivirus programs:

    Virus, Spyware, and Malware Protection and Removal Resources

  • Update your AntiVirus Software - It is imperitive that you update your Antivirus software at least once a week (Even more if you wish). If you do not update your antivirus software then it will not be able to catch any of the new variants that may come out.

  • Use a Firewall - I can not stress how important it is that you use a Firewall on your computer. Without a firewall your computer is succeptible to being hacked and taken over. I am very serious about this and see it happen almost every day with my clients. Simply using a Firewall in its default configuration can lower your risk greatly.

    For a tutorial on Firewalls and a listing of some available ones see the link below:

    Understanding and Using Firewalls

  • Visit Microsoft's Windows Update Site Frequently - It is important that you visit http://www.windowsupdate.com regularly. This will ensure your computer has always the latest security updates available installed on your computer. If there are new updates to install, install them immediately, reboot your computer, and revisit the site until there are no more critical updates.

  • Install Spybot - Search and Destroy - Install and download Spybot - Search and Destroy with its TeaTimer option. This will provide realtime spyware & hijacker protection on your computer alongside your virus protection. You should also scan your computer with program on a regular basis just as you would an antivirus software.

    A tutorial on installing & using this product can be found here:

    Using Spybot - Search & Destroy to remove Spyware , Malware, and Hijackers

  • Install Ad-Aware - Install and download Ad-Aware. ou should also scan your computer with program on a regular basis just as you would an antivirus software in conjunction with Spybot.

    A tutorial on installing & using this product can be found here:

    Using Ad-aware to remove Spyware, Malware, & Hijackers from Your Computer

  • Install SpywareBlaster - SpywareBlaster will added a large list of programs and sites into your Internet Explorer settings that will protect you from running and downloading known malicious programs.

    A tutorial on installing & using this product can be found here:

    Using SpywareBlaster to protect your computer from Spyware and Malware

  • Update all these programs regularly - Make sure you update all the programs I have listed regularly. Without regular updates you WILL NOT be protected when new malicious programs are released.
Follow this list and your potential for being infected again will reduce dramatically.

Glad I was able to help.

Hello Grinler
I am confused because the scan I ran, before sending you the log, using Ad-Ware with avast! on shows I still have the Trojano.
Avast! warns me there is a virus and I quarantine it.
I have since done another scan with the same result, the virus is still here (?).
The instructions to safeguard my pc I did last week on the recommendation of a member on this site after removing 3 pop ups that I couldn't remove on my own.
I hate to nag on about this but I really am confused!
Any suggestions??
Regards Ian
