Hi!
I don't know what to do. My computer has been running slow when I use the internet. It is at 100% usage. I ran McAfee and everything was fine. I did a registry clean by running ICare (advanced system care) and nothing helped. If anyone can help me read the log file of Hijack This, I'd really appreciate it. I'm also wondering if it's possible an out of town guest staying at my apartment installed some sort of program to be able to remote on to my computer or take my passwords(which I know he has done to others). When he was over, I found something happening with C:\WINDOWS\system32\oobe\actshell.htm. If anyone can tell me what this is, I'd appreciate it. I've uploaded the log files for hijack this and for the day I saw him doing something strange.

Thanks!

Hello.

Please run Malwarebytes then followed by GMER.

Afterwards take a new DDS run and post back with the logs. Please give me a description of any problems you may still have.

Download and run MalwareBytes Anti-Malware

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
  • Make sure you are connected to the Internet.
  • Double-click on Download_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 and you may be prompted to restart your computer. (see Note below)
  • 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 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. Failure to reboot will prevent MBAM from removing all the malware.

For complete or visual instructions on installing and running Malwarebytes Anti-Malware please read this link

Download and Run Scan with GMER

We will use GMER to scan for rootkits.This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop. Unzip/extract the file to its own folder. (Click here for information on how to do this if not sure. Win 2000 users click here.
  • Close any and all open programs, as this process may crash your computer.
  • Double click Posted Image or Posted Image on your desktop.
  • When you have done this, close all running programs.
    There is a small chance this application may crash your computer so save any work you have open.
  • Double-click on Gmer.exe to start the program. Right-click and select Run As Administrator... if you are using Vista
  • Allow the gmer.sys driver to load if asked.
    If it detects rootkit activity, you will receive a prompt (refer below) to run a full scan. Click NO..
    Posted Image
  • In the right panel, you will see several boxes that have been checked. Please UNCHECK the following:
    • Sections
    • IAT/EAT
    • Registry
    • Drives/Partition other than Systemdrive (typically C:\)
    • Show all (Don't miss this one!)
  • Click on Posted Image and wait for the scan to finish.
  • If you see a rootkit warning window, click OK.
  • Push Posted Image and save the logfile to your desktop.
  • Copy and Paste the contents of that file in your next post.

If GMER doesn't work in Normal Mode try running it in Safe Mode

Hi, Thanks for opening it again and sorry for the delay in response. I've still been having problems. My computer is at 100% usage, I've noticed that things are checked off that I don't check (like, "keep me logged in"), MS word and other programs have dissapeared or don't open, and I get messges when I log in to email accounts that I can't log in because someone else is logged in. I really think my houseguest did something to my computer. I know he's been able to get on to someone else's computer and steal e-mail passwords. Can you check the files from my first post and see what the out of box experience thing was? He was doing something and when I looked, I found that. Thanks for your help! I'm attaching the malwarebytes log from today and 7/3 when I frist ran it. I'm running the gmer now.

Hi, I found this file B3BB5BBA-E7D5-40AB-A041-A5B1C0B26C8F installed in C:\WINDOWS\system32\oobe\actshell.htm that happened during the time I think someone installed something on my computer.

I did a google search and found this:

Cons: Software\Microsoft\Internet
Explorer\Security\AntiPhishing\B3BB5BBA-E7D5-40AB-A041-A5B1C0B26C8F]. Altering IE7's BUILT IN antiphishing protection is never a good sign that thIs particular programmer loves you.

Summary: It Iinstalled a keylogger & potential rootkit, tho I'm not sure. It made a HTM file & a DAT FILE called
B3BB5BBA-E7D5-40AB-A041-A5B1C0B26C8F.dat, safely hidden away in local settings, where you'll never see it. it's not in hex, must be encrypted


Does it mean that he installed something on my computer?
Thanks

Hello.

Hi, I found this file B3BB5BBA-E7D5-40AB-A041-A5B1C0B26C8F installed in C:\WINDOWS\system32\oobe\actshell.htm that happened during the time I think someone installed something on my computer.

I have the same file ("B3BB5BBA-E7D5-40AB-A041-A5B1C0B26C8F.dat") in my local settings directory on my XP machine as well.

Please run DR.Web Cure IT then post a new DDS run afterwards.

Download and Run DrWebCureIt in Safe Mode

Before we start fixing anything you should print out these instructions or copy them to a NotePad file so they will be accessible. Some steps will require you to use Safe Mode and you will not have access to this page.

Please download DrWeb-CureIt and 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 the drweb-cureit.exe file and click Scan to run express scan. Click OK in the pop-up window to allow the scan.
  • This will scan the files currently running in memory and if something is found, click the Yes button when it asks you if you want to cure it. This is only a short scan.
  • Once the short scan has finished, select Complete scan.
  • Click the green arrow Posted Image at the right, and the scan will start.
  • Click Yes to all if it asks if you want to cure/move the file.
  • When the scan has finished, in the menu, click File and choose Save report list
  • Save the report to your desktop. The report will be called DrWeb.csv
  • Note: This report may need to be renamed to Dr.Web.txt in order to post it on the forum.
  • Exit Dr.Web Cureit.
  • Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
  • After reboot, post/attach the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)
Post back with the DR.WEB CUre IT log and a new set of DDS logs.

With Regards,
Extremeboy
Note: Please do not PM me asking for help, instead please post it in the correct forum requesting for help. Help requests via the PM system will be ignored.

Hi! Thanks again for your help. Here are my dds logs and drweb results. Also, can you please let me know if the log from the first post I gave said anything bad was done. And, does that mean that file B3BB5BBA-E7D5-40AB-A041-A5B1C0B26C8F is okay even though the other thing I read online said it was bad?

Here is the DrWeb stuff. It found two things. I clicked cure but then it asked if I wanted to rename or delete and since I didn't know what it was, I chose rename.

mcinst.exe;C:\Program Files\Common Files\McAfee\Installer;Probably BACKDOOR.Trojan;Incurable.Renamed.;
A0221597.exe;C:\System Volume Information\_restore{DFCED1AE-E1D5-4632-8F18-89C5F38CA2A1}\RP83;Probably BACKDOOR.Trojan;Incurable.Renamed.;

Also, a friend looked at my computer and said that something was deleted or going on with my server setting or something like that and if someone was logging on they could have just deleted it. And, my computer last night just froze up and I couldn't see any icons on my desktop. What's going on?

Thanks for your help!

Sorry, one more thing. Can you tell me if anything is wrong. I have no clue how to read these logs. Thanks!

And just one more thing. The log files for a period of time when I was on the computer and it was acting funny and the computer icons dissapeared and only the background showed up (this was about an hour last night). What could have happened? Could I delete that myself by running one of these scans?

Sorry... they are too big to upload.

There are no postings between 2:03:17 AM and 3:06:24 AM however I was on the computer and I was doing things like going on e-mail, running IE Privacy Keeper scans, etc. I noticed at around three a.m. that my computer started freezing and I couldn’t see my desktop.
