Hi,

I have a Dell laptop M1210 running Windows XP with window internet explorer as my browser. Lately I have been having problems online with popups and some operating irregularities (i.e. slowness, explorer shutting down)

I am running a purchased version of Trendmicro devices p-cillian (which is up to date). Also I am running free versions of AVG8.5 and a-squaredfree. These are both up to date as well. Additionally, I have the Trendmicro devices set as my firewall software. I run both schedule and unscheduled virus protection on a regular basis.

About the time my system slowed I ran an unscheduled virus check with A-squared and found a couple of Trojans including a vundo trojan, which were removed to the quartine section. But since than the system seems to be acting worse. I attempted to do a system restore but the restore is not successfully completing and no change is therefore made to the system (does not seem to matter what restore date I try to us).

Any help would be appreciated.

Thanks
:thumbsup:

Hello and welcome to Bleeping Computer. First, I want to let you know that running multiple antiviruses will conflict. I would suggest you keep the Trend Micro, and then remove the AVG and A-Squared. This can cause slowness, errors, and much more on your machine. After you have done so then please follow the remaining instructions:

:flowers:Please subscribe to your topic so that you will be notified as soon as I post a reply, instead of you having to check the topic all of the time. This will allow you to get an email notification when I reply.

To subscribe, go to your topic, and at the top right hand corner by your first post, click the Options button and then click Track this topic. The bullet the immediate notification bubble. Then press submit.


:thumbsup: Lets take a look with Malwarebytes

Please download Malwarebytes' Anti-Malware from here:
Malwarebytes
Please rename the file BEFORE downloading to zztoy.exe instead of mbam-setup.exe

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.

Double Click zztoy.exe to install the application.
* Make sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select "Perform Full Scan", then click Scan.
* The scan may take some time to finish,so please be patient.
* When the scan is complete, click OK, then Show Results to view the results.
* Make sure that everything is checked, and click Remove Selected.
* When disinfection is completed, a log will open in Notepad and you may be prompted to Restart.(See Extra Note)
* The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
* Copy&Paste the entire MBAM report (even if it does not find anything) in your next reply

Extra Note:
If MBAM encounters a file that is difficult to remove,you will be presented with 1 of 2 prompts,click OK to either and let MBAM proceed with the disinfection process, if asked to restart the computer, please do so immediately.


If Malwarebytes won't install or run

Some types of malware will disable MBAM and other security tools. If MBAM will not install, try renaming it. Right-click on the mbam-setup.exe file and change the .exe extension to .bat, .com, .pif, or .scr and then double-click on it to run.

If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files, right-click on mbam.exe and change the .exe as noted above. Then double-click on it to run.

You rename the file just in case the malware may try to block the running of the setup file, so basically, you trick it into thinking it is something else.

That makes sense.

Two things,

1). Malwarebytes came up with an error on the load. I recevied the following windows message:

Unable to excute file:
C:\Programfiles\Malwarebytes'Anti-malware\mbam.exe

Create Process failed; Code 2.
The system cannot find the file specified


-----------
(Also I looked under the folder on the director and can not locate an mbam file manually.)


2). I subscribed as you indicated and it came up with an error indicated I was already subscibed, but I did not get a notification of your last post.

Thanks again for your assistance

Ok, lets try Dr. Web:

Please download Dr. Web the free version & save it to your desktop. DO NOT perform a scan yet.

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr. Web Cureit as follows:
• Double-click on launch.exe to open the program and click Start. (There is no need to update if you just downloaded the most current version
• Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
• The Express scan will automatically begin.
(This is a short scan of files currently running in memory, boot sectors, and targeted folders).
• If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
• If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All.
• When complete, click Select All, then choose Cure > Move incurable.
(This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
• Now put a check next to Complete scan to scan all local disks and removable media.
• In the top menu, click Settings > Change settings, and UNcheck "Heuristic analysis" under the "Scanning" tab, then click Ok.
• Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
• When the scan is complete, a message will be displayed at the bottom indicating if any viruses were found.
• Click "Yes to all" if asked to cure or move the file(s) and select "Move incurable".
• In the top menu, click file and choose save report list.
• Save the DrWeb.csv report to your desktop.
• Exit Dr.Web Cureit when done.
• Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
• After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)

For some reason, I guess the site has started to make it's default language Russian. But if you go to the same website, and then go up to the top right hand corner of the webpage, then there is a dropdown box where you can change the language to English.

Computer Pro,

So I donwload Dr. Webb launch and than rebooted in safe mode. I launched the memory scan in safe mode and got the following error :

9lvf7XP.exe
9lvf7XP.exe has encountered a problem and needs to close. We are sorry for the inconvenience


Than this message came up:

Warning! Viruses or suspicious objects have been detected during the scanning.

The Quarantine location is C:\Documents and Settings\Managing System\DoctorWeb\Quarantine\

The Log File location is C:\Documents and settings Managing System|DoctorWeb\CureIt.log

It is strongly recommended to perform a Complete scan of your system if it hasn’t been performed during scanning. You can customize the response of Dr. Webb CureIt! To detection of virsuses in the scanner window……

---------------

I hit the X to close when offered to purchase the full version at which point no other action was presented on the screen.

I looked on my system for the quarantine items and log items were there, no files and no DoctorWeb folder. Searched for DoctorWeb folder on c: drive nothing.

other suggestions?

Thanks

Its not unusual to receive such an error after using specialized fix tools.

A "Cannot find...", "Could not run...", "Error loading... or "specific module could not be found" message is usually related to malware that was set to run at startup but has been deleted. Windows is trying to load this file but cannot locate it since the file was mostly likely removed during an anti-virus or anti-malware scan. However, an associated orphaned registry entry remains and is telling Windows to load the file when you boot up. Since the file no longer exists, Windows will display an error message. You need to remove this registry entry so Windows stops searching for the file when it loads.

To resolve this, download Autoruns, search for the related entry and then delete it.

Create a new folder on your hard drive called AutoRuns (C:\AutoRuns) and extract (unzip) the file there. (click here if you're not sure how to do this.)
Open the folder and double-click on autoruns.exe to launch it.
Please be patient as it scans and populates the entries.
When done scanning, it will say Ready at the bottom.
Scroll through the list and look for a startup entry related to the file(s) in the error message.
Right-click on the entry and choose delete.
Reboot your computer and see if the startup error returns.


Did you run the step..click Next to view the final action taken.


Please rerun Rootrepeal. In step 6 select only files.Post another log,thanks.
