My Dell Inspiron 9300 has been hit with some malware. I followed a few of the posts on www.bleepingcomputer.com because I found a few posts that were very similar to my problem. I went and downloaded Spybot and Malwarebytes' Anti-malware. I updated and used Spybot as the forum directed. Spybot found many infected files and registry keys. I finished up the process involved with Spybot but when I repeated my scans to make sure the problems were gone they would re-appear in the next scan even though I was told by Spybot that the problems had been dealt with. I then tried Malwarebytes' Anti-Malware. After updating and scanning, 35 infected/untrusted items were found and dealt with. I scanned again after rebooting and this time only 2 items were detected as infected. So I have 2 repeating little devils, which is much better than the old 35 infected items. My 2 repeating offenders are Trojan.Vundo and Malware.Trace

The post at this link http://www.bleepingcomputer.com/forums/lof...hp/t129477.html
is very similar to my problem but I need some 1 on 1 help so I can carry out the same instructions given to user mg99t but for my specific system config. I have found this site very useful over the past 2 days and I have already partially solved the problem by simply reading over this great site. My computer is already behaving better but I want to make sure I finish off the Trojan.Vundo and Malware.Trace for good. Bleepingcomputer.com is definately worth donating some money too and I already intend to make a donation in the near future.
I take instructions quite well and I use Windows XP Home Edition.

Your MBAM log indicates you are using an older version of MBAM with an outdated database. Please download and install the most current version (1.32) from here.
You may have to reboot after updating in order to overwrite any "in use" protection module files.

Afterwards, please update the database through the program's interface ((preferable way)) or manually download the updates and just double-click on mbam-rules.exe to install. Then perform a new Quick Scan in normal mode and check all items found for removal. Don't forgot to reboot afterwards. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. When done, click the Logs tab and copy/paste the contents of the new report in your next reply.

The first time I used MBAM, before I posted, I was not able to use the internet on my infected machine. So I had to burn the mbam-rules.exe onto a CD so I could get the updates on my infected machine. However, the link I used from the other post I was reading may have been too old or my update file never setup even though I had thought it did. I didn't want to go on the internet with the infected PC but I managed to now get the MBAM to update. I got a new trojan while on the net with my infected machine called Artemis but my McAfee said it was now quarantined. So if you see some new threats in this next report, they could have jumped on my machine when I quickly connected to get the MBAM update or they could have been overlooked by my outdated version of MBAM. I keep my infected PC unhooked from any internet and I turn my McAfee Real Time scanning off when using MBAM. Just wanted to keep you filled in on the details.
Here is my up to date MBAM log.

Now rescan again with MBAM but this time perform a Full Scan in normal mode and check all items found for removal. Don't forgot to check for database updates through the program's interface (preferable way) before scanning and to reboot afterwards. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. When done, click the Logs tab and copy/paste the contents of the new report in your next reply.

My McAfee has been running really slow lately. But my latest McAfee update seems to have smoothed things out in that department.
Spyware programs aren't picking up anything anymore. I'll keep updating anti-spyware and scanning from now on.

Thanks for solving my computer problem.

You're welcome.

If there are no more problems or signs of infection, you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista Users can refer to these links: Create a New Restore Point and Disk Cleanup.

Tips to protect yourself against malware and reduce the potential for re-infection:Avoid gaming sites, pirated software, cracking tools, keygens, and peer-to-peer (P2P) file sharing programs. They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and malicious Flash ads that install viruses, Trojans and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users. The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications. Read P2P Software User Advisories and Risks of File-Sharing Technology.

Keeping Autorun enabled on USB and other removable drives has become a significant security risk due to the increasing number of malware variants that can infect them and transfer the infection to your computer. When is AUTORUN.INF really an AUTORUN.INF?. For more information on this risk, please read USB-Based Malware Attacks and Please disable Autorun asap!.
