windows 7 extremely slow and issue with bitmap

June 24, 2013 at 14:10:01
Specs: Windows 2008
I have this dell windows 7 home premium laptop with a 500GB HDD and 6GB for RAM. At first I was able to get on to the internet but it was extremely slow. A couple of days ago I was not able to even open Mozilla Firefox or internet explorer unless i was in safe mode with networking. I also noticed that I couldn't open my computer or control panel and when I went to start and all programs nothing was there. I did a chkdsk and it said error with bitmap master file. then i did chkdsk /f and chkdsk again and it seemed to have fixed it for a while. But when I tried to go into control panel it would not open the categories so i thought it was a virus. I opened microsoft security essentials and it stopped halfway through the update. I went to performance in task manager and it said the computer was only 2GB of data and my harddrive has 30GB filled. I could really use some help. thank you!

" I could really use some help. thank you!"
It could be anything, I prefer to start by checking for infections.

1: Download & run Unhide
A introduction as to what this program does.
For those of you who no longer have the %Temp%\Smtmp folder, you will not be able to use Unhide to restore your Start Menu items. With this in mind, I have created some scripts to restore the default Start Menu for specific versions of Windows that I have access to. You can view the available versions below. I will be adding more as time goes on.
Once the program has been downloaded, double-click on the Unhide.exe icon on your desktop and allow the program to run, it does take some time, be patient. This program will remove the +H, or hidden, attribute from all the files on your hard drives. If there are any files that were purposely hidden by you, you will need to hide them again after this tool is run.
When Unhide is complete, it will create a logfile on the Windows Desktop called Unhide.txt.
Copy & Paste the contents of the log. Let me know if it doesn't produce a log please.

2: Reboot

3: Run ESET Online Scanner, Copy and Paste the contents of the log please. This scan may take a very long while, so please be patient. Maybe start it before going to work or bed.
You may have to download ESET from a good computer, put it on a flash/thumb/pen drive & run it from there, if your comp is unbootable, or won't let you download.
Create a ESET SysRescue CD or USB drive
How do I use my ESET SysRescue CD or USB flash drive to scan and clean my system?
Configure ESET this way & disable your AV.
How to Temporarily Disable your Anti-virus
Why Would I Ever Need an Online Virus Scanner?
I already have an antivirus program installed, isn't that enough?
Once onto a machine, malware can disable antivirus programs, prevent antimalware programs from downloading updates, or prevent a user from running antivirus scans or installing new antivirus software or malware removal tools. At this point even though you are aware the computer is infected, removal is very difficult.
5: Why does the ESET Online Scanner run slowly on my computer?
If you have other antivirus, antispyware or anti-malware programs running on your computer, they may intercept the scan being performed by the ESET Online Scanner and hinder performance. You may wish to disable the real-time protection components of your other security software before running the ESET Online Scanner. Remember to turn them back on after you are finished.
17: How can I view the log file from ESET Online Scanner?
The ESET Online Scanner saves a log file after running, which can be examined or sent in to ESET for further analysis. The path to the log file is "C:\Program Files\EsetOnlineScanner\log.txt". You can view this file by navigating to the directory and double-clicking on it in Windows Explorer, or by copying and pasting the path specification above (including the quotation marks) into the Start ? Run dialog box from the Start Menu on the desktop.
If no threats are found, you will simply see an information window that no threats were found.

toasterlvr ,I would venture to say that there is an unwanted rootkit installed. It is a proven method that works most all the time.
Just download and run these 3 free progs in EXACTLTY the order listed and DO NOT reboot until after the last scan has run.
1- rkill.exe
2- tdss killer
3- Malwarebytes

I use this first on all the tech repairs I do in my shop for starters....if the problem persists try the EXACT SAME order in Safe Mode. Let us know how things go. Thanks

Some HELP in posting on plus free progs and instructions 7 Golds
