What program is alerting you to the infection?

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 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.
  • 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 may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes, they may alert you after scanning with MBAM. Please permit the program to allow the changes.

If AVG is providing the alerts, it should also be indicating the specific files involved and their location (full file path). Please provide that information.

Your MBAM log indicates you are using an older version of MBAM with an outdated database. Please download and install the most current version of MBAM from here.

Perform a new Quick Scan in normal mode and check all items found for removal. Don't forgot to reboot afterwards. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. When done, click the Logs tab and copy/paste the contents of the new report in your next reply.

You may have deleted them instead of moving to the vault.

To be safe, 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. Then use Disk Cleanup to remove all but the most recently created Restore Point.

Then keep monitoring your system for the next couple days. If something is detected again, write down the full name/file path and post back in this thread with that information.

Yes you can put it in the vault...just be sure to write down all the info on the threat as that will help determine what it is.

If your computer seems to be slow, read Slow Computer/Browser? Check here first; it may not be malware. There are reasons for slowness besides malware - i.e. disk fragmentation, disk errors, corrupt system files, too many startup programs, unnecessary services running, not enough RAM, dirty hardware components, etc. As your system gets older it becomes filled with more files/programs and has a natural tendency to slow down so cleaning and regular maintenance is essential.

A slow browser is a common complaint with various causes and possible solutions. What works for one person may not work for another. If you are having trouble logging into a website or Internet Explorer is behaving oddly, you may need to clear your cookies and temporary Internet files (browser cache). As you browse web pages, the browser stores a copy of the pages you view on your local hard drive and this is called caching. Clearing the cache forces the browser to load the latest versions of Web pages and programs you visit.

"How to Clear Cookies and Cache in Internet Explorer 6"
"How to Clear Cookies and Cache in Internet Explorer 7"
"How and Why to Clear Your Cache"

Also see "Its not always malware: How to fix the top 10 Internet Explorer issues" and "Get to the bottom of a slow Internet connection".

If your using Vista or Internet Explorer 7, see:
"Why is my Internet connection so slow?".
"Windows Vista - My Internet connection is slow".
"Tuning IE7 for Better Performance".
"Speedup Internet Explorer 7".
"How to optimize or reset Internet Explorer 7".

The Phishing Filter could be causing your computer to respond very slowly as it evaluates Web page contents. See "The Phishing Filter may slow down the PC" and "Phishing Filter FAQs".

If you have a lot of BHOs and add-ons attached to Internet Explorer, you could try improving performance by disabling those which are unnecessary. Sometimes add-ons cause Internet Explorer to quit unexpectedly or not perform properly especially if the add-on was poorly designed or was created for an earlier version of Internet Explorer. Incompatible browser extensions and add-ons can also cause compatibility issues such as application hangs in IE. See Control Internet Explorer Add-ons with Add-on Manager and Troubleshooting and Internet Explorerís (No Add-ons) Mode. Vista users see Internet Explorer Add-ons FAQs.
