Hello there, our AVG on my parents laptop just went crazy...twice, It gave us two alerts and here are the logs

Resident Shield detection
"Infection";"Object";"Result";"Detection time";"Object Type";"Process"
"Trojan horse SHeur2.WPO";"C:\System Volume Information\_restore{AF7EF6C5-FDEF-4D9E-B628-73B618EEEA12}\RP633\A0132091.exe";"Moved to Virus Vault";"21/03/2009, 10:15:18";"File";"C:\WINDOWS\system32\svchost.exe"
"Trojan horse SHeur2.WPO";"C:\Program Files\AtcomUsbDialer\AtcomUsbDialer.exe";"Moved to Virus Vault";"19/03/2009, 16:46:42";"File";"C:\WINDOWS\explorer.exe"

Not sure what its doing at the moment but have tryed the folling programs to no avail, they didnt even find it! (Note: I was running in safe mode and had updated all programs beforhand)

In order of use:
1. CCleaner
2. Spybot S&D
3. MBAM
4. SAS
5. AVG

None found it and it hasnt acted up again since but i know its there, how can it not be if none of my scanners found it.

Thanks, Wolfy87.

Hello. It appears to have been found ansd quarantined by AVG. None of the others show it. Now there is one left in your System restore. We can clean tat then rerun an AVG scan.

Now you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista Users can refer to these links: Create a New Restore Point and Disk Cleanup.
