Solved Rootkit Virus killed my computer. Restored but still too slow to use?!

[SoapDodger]

Hey Guys.

My computer was recently infected with a rootkit virus from what I could tell. When first discovered, my virus check took 38 hours and found 6898 virus's, I moved these to the chest and predictebly it killed windows, I was unable to boot into it or safe mode.

I used my installation of Ubuntu to back up important files and to try and troubleshoot the problem.

So to solve the problem, I first recovered windows using my recovery discs then I used an image backup to recover my programs (Note: The image was created a year prior to the virus therefore definitely clean). So I am now able to access Windows.

Problem:

My computer is running incredibly slow. It is unusable! I cannot open any program without it crashing and then I have to wait for it to reciver itself. I have run a further virus scan which brought up nothing. The Ram is registering at 2.78GB (Usable) which is about right considering I only have 3GB.

I have run an error check on my hard drive and there were no errors. I have started to (albeit slowly) uninstall unwanted programs and clear system files. I am trying to eliminate everything but it really is annoying me.

I am open to suggestion on what the problem may be.

Additional Info:

I opened up the Event Viewer and in the last 24 hours there have been over 500 errors. Also I use Avast Free to protect my computer

Hope some one can suggest some tests or solutions to my problem Cheers.

Suggest you run a scan with Windows Offline Defender to see what it finds. D/L this on a different PC & run it on yours.

Most rootkits write a hidden boot partition which may not have been erased. Run this tool as well and post the results:

Anti-rootkit utility TDSSKiller

It's best to wipe the HDD first with Diskpart Clean Command

then Clean Reinstall - Factory OEM Windows 7 following the best practices in the tutorial to get a perfect reinstall.

After set up save a Win7 backup image to external once you have a perfect reinstall to wiped HD.

then use
ccleaner to clean the computer from temp files

 

[kefah]

what is your antivirus program

 

[gregrocker]

Do not use any Registry cleaners or Optimizers besides CCleaner. Tune Up Utilities is also to be avoided.

You need to make sure you're disinfected using Borg's approach, or wipe the HD to get the freshest start.

can u explain if u dont mind

 

[gregrocker]

We see a lot of problems with Win7 being ruined by Registry Cleaners and Optimizing Suites. Most Registry Cleaners are sales operations with no genius behind them. It requires the highest level of genius to avoid damaging the registry. Only CCleaner has come through as fully trustworthy over more than 15 years. No claims of it damaging the registry are able to be confirmed, while we confirm others regularly.

However your idea to run SFC /scannow is good, once OP has fully disinfected his system.

so which program u advice me to use to maintenance pc

 

[gregrocker]

If you've used those tools you mentioned then I would Clean Reinstall - Factory OEM Windows 7 using only the methods and tools mentioned in the tutorial to reinstall, setup and maintain Win7.

Hi,

The advise the guys have given regaring Registry cleaners is so true... I used to use them all Advanced system care, system mechanic....and many more...stay well alway from them ... Ccleaner is the daddy it has all you need.

My PC has run so much better since coming on Seven Forums and taking the advise regarding using Ccleaner only

Hope this helps

Thanks for all the comment s guide, I've been struggling to get internet access lol hence the late reply.

Just a quick update, I used the verification scan using sfc /scannow and that failed, it stopped at 71% and said it couldn't complete. I tried the windows defender offline and that found nothing. I am now trying the anti-rootkit scan by Kapersky which was suggested first...

Thanks again

 

[SoapDodger]

Update: After running the Root-kit it seems to have solved the problem and sorted my computer out however I am still going to do a full re-install the proper way as the verification scan still won't complete. Thanks for providing the tutorial I shall be using today.

Cheers, Dan.

I'd wipe the HD first with Diskpart Clean Command before Clean Reinstall - Factory OEM Windows 7.

I am facing some problems to remove the virus Mybrowserbar.com.
I tried to remove the virus in several ways, but there is no use.
In google I found the webpage mygoodpc.com regarding this virus. In that webpage, some instructions are there to remove the virus by using various Virus Removal Tools. I followed all the instructions in that webpage, but unfortunately can't download those Tools. May be Mybrowserbar.com virus blocking the downloads. Give me suggestions to remove the virus completely from my PC.
