I have been hit with a virus or some kind of malware. It has corrupted some files for my principal user ID. Admin and other users seem unaffected.
I am planning to go thru the steps in the Preparation Guide topic.

My question is, should I do all this as the affected user, admin, or another user?

Thanks for your help!

Hello and welcome. First I will move this to the Am I Infected forum fro Vista.
Before we do that do this.

From your Admin account
Next run MBAM (MalwareBytes):

Please download Malwarebytes Anti-Malware (v1.44) and save it to your desktop.alternate download link 1
alternate download link 2
MBAM 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.
  • 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.
Next run ATF and SAS: If you cannot access Safe Mode,run in normal ,but let me know.

Note: On Vista, "Windows Temp" is disabled. To empty "Windows Temp" ATF-Cleaner must be "Run as an Administrator".

From your regular user account..
Download Attribune's ATF Cleaner and then SUPERAntiSpyware , Free Home Version. Save both to desktop ..
DO NOT run yet.
Open SUPER from icon and install and Update it
Under Scanner Options make sure the following are checked (leave all others unchecked):
Close browsers before scanning.
Scan for tracking cookies.
Terminate memory threats before quarantining
.
Click the "Close" button to leave the control center screen and exit the program. DO NOT run yet.

Now reboot into Safe Mode: How to enter safe mode(XP)
Using the F8 Method
Restart your computer.
When the machine first starts again it will generally list some equipment that is installed in your machine, amount of memory, hard drives installed etc. At this point you should gently tap the F8 key repeatedly until you are presented with a Windows XP Advanced Options menu.
Select the option for Safe Mode using the arrow keys.
Then press enter on your keyboard to boot into Safe Mode
.

Double-click ATF-Cleaner.exe to run the program.
Under Main "Select Files to Delete" choose: Select All.
Click the Empty Selected button.

If you use Firefox or Opera browser click that browser at the top and choose: Select All
Click the Empty Selected button.
If you would like to keep your saved passwords, please click No at the prompt.
Click Exit on the Main menu to close the program
.

NOW Scan with SUPER
Open from the desktop icon or the program Files list
On the left, make sure you check C:\Fixed Drive.
Perform a Complete scan. After scan,Verify they are all checked.
Click OK on the summary screen to quarantine all found items.
If asked if you want to reboot, click "Yes" and reboot normally.

To retrieve the removal information after reboot, launch SUPERAntispyware again.
Click Preferences, then click the Statistics/Logs tab.
Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
If there are several logs, click the current dated log and press View log.
A text file will open in your default text editor.
Please copy and paste the Scan Log results in your next reply.
Click Close to exit the program.

The story thus far:

I was attempting a download from a file hosting site when I began receiving clearly false “Vista Security” warnings. My paid AVG did not catch the virus, what ever it was. I shut down the connection. I eventually discovered what seemed to be the problem file, ave.exe, by the date and time of modification. I deleted this file. Effects of the virus seemed to be the disabling of some programs from the desktop or start menu. Example. I use Irfanview for basic image editing. It would not open from the desktop, asking what program I wanted to use to open it with. However, when I click on an image file, the program will open and run normally. AVG would not run at all.
I logged in as admin. Everything seemed to run normally. No indication of any problem. Tried one of my spare user IDs. Everything runs fine.
As admin, I updated and ran a full scan with AVG, found nothing. Likewise Windows Defender. I called the help desk at Smart Computing magazine. They told me to download and run Malwarebytes and Combo-fix. I downloaded, updated, and did a full scan with MWB. Found nothing! During this time AVG popped up a dialog about removing some file which might cause a problem. I dis-regarded this.
I went to the site for Combo-fix and saw all the warnings. I didn't download it or anything. Did see the references to various helpful forums, so here I am. :-)
A later scan with AVG found this, and moved it to the Vault:
"C:\Users\Richard\AppData\Local\Microsoft\Windows\Temporary Internet Files\Content.IE5\LQ9Z8GJA\n008106201318r0409J0d000601Rd3184286Wff17ebeaXfb3f9dcdYb0969f70Z0100f0700[1]" ; "Trojan horse Generic17.PSN" ; "Moved to Virus Vault"
This naturally did not solve anything.

I have since been operating as my spare user, with no problems. However I want to fix the problem, not just work around it.

I just updated MWB and did a new full scan. Nothing found. Log:
Database version: 3930
Windows 6.0.6002 Service Pack 2
Internet Explorer 7.0.6002.18005

Scan type: Full scan (C:\|D:\|)
Objects scanned: 325614

Memory Processes Infected: 0
Memory Modules Infected: 0
Registry Keys Infected: 0
Registry Values Infected: 0
Registry Data Items Infected: 0

Shall I continue with ATF and SAS?

Thanks!

Hello. I forgot to ask what is your operating System. SAS needs to be run on all user accounts.

Downloaded the files, updated, scanned, as instructed. Scanned in safe mode. All that SAS found were tracking cookies during the first run. Having removed those, it found nothing when scanning the other 2 users. Summary of logs as follows:

Software still won't run normally for the affected user, but fine for the other two. I seem to recall that Vista has a way to transfer one user's info to another. Is that the next step?

You look malware free,.
