All my antivirus programs show no infections. But while Clamwin antivirus is running an Avast window comes up with this info -

Win32:Trojan-gen {Other}
C:\docume~1\me67e5~1.dor\locals~1\temp\clamav-062b9cdb73c
090102-0, 01/02/2009

I clicked on "move to virus chest" which was recommended, but it keeps coming up. Then Clamwin continues to run and gives a no infection message when done.

In the Event Viewer I find -

Sign of "Win32:Trojan-gen {Other}" has been found in "C:\docume~1\me67e5~1.dor\locals~1\temp\clamav-ac3398939e16142c8f3d709055c3e8c3.00000468.clamtmp" file.

Firefox is slow to come up, the out line of the window comes up and fills in after a few seconds. I was having trouble with it crashing and found I should update to newest version, but it is still going unresponsive frequently.

Thanks,
Dorothy

Are you using Clamwin and Avast as resident antivirus? If so, the two will conflict and possibaly give false positives - on both sides. If you are using Clamwin independently, you may wish to disable Avast until your scan finishes.

We can Take a look with malwarebytes...

The process of cleaning your computer may require temporarily disabliling some security programs. If you are using SpyBot Search and Destroy, please refer to Note 2 at the bottom of this page.

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.

Note 2:
-- MBAM may make changes to your registry as part of its disinfection routine. If you're using other security programs that detect registry changes (like Spybot's Teatimer), they may interfere with the fix or alert you after scanning with MBAM. Please disable such programs until disinfection is complete or permit them to allow the changes. To disable these programs, please view this topic: How To Temporarily Disable Your Anti-virus, Firewall And Anti-malware Programs

OK. I should have known to turn off Avast. With that off, Clam produced this -

Avast still says no infection. I already had MAB and it says the same. Will run Spybot without Avast on, but that takes hours.

Browser very slow in coming up and running. Modem keeps dialing itself when I disconnect. I have tried to turn off all the timed updates.

Forgot to add that while on the internet I frequently get a message -

"Prevx Computer Security Investigator has encountered a problem and needs to close. We are sorry for the inconvenience."

I close the window and that is it.
Is this program working properly or is it detecting a problem?

As far as I know, those files are secured by Windows.

Thses files are owned by Malware scanners and would show up as a false positive.

I think you are clean.

Take a look here: Slow Computer
You may have a problem with you modem trying to redial when disconnected, or when a connection is lost. There is a setting somewhere in your dialer software that would stop that. There is also a chance your modem may be bad.

Let me ask another helper to take a look...

I'd suggest uninstalling PrevX CSI - as your system is having problems with it. You can reinstall it later on (once these issues are fixed).

I'd also suggest cleaning out the C:\docume~1\me67e5~1.dor\locals~1\temp\ folder - just in case something's hiding in there.

Finally, I'd suggest backing up your bookmarks ( http://support.mozilla.com/en-US/kb/Backin...our+information or use the Foxmarks extension to backup online).
and then uninstalling Firefox according to these directions: http://support.mozilla.com/en-US/kb/Uninstalling+Firefox
Be sure to follow the steps under the section "Removing user data and settings"
Download a fresh copy of Firefox, install it and import your bookmarks.
Then test to see how it's running. If all's OK, then you can start adding in your addons.
