About a week or two ago, my computer somehow picked up a virus called Windows Home Security 2012. I downloaded a trojan remover and it removed the virus from my computer, but I'm not sure if it wiped it out completely. I use both google chrome and firefox. Firefox keeps freezing, pages load painfully slow, and when I click on a link, I am usually redirected to a random site or the page will be a blank white screen. Firefox also keeps opening random tabs on it's own, which redirect to random sites as well. Google Chrome, on the other hand, just runs very slow. My computer is also saying that my automatic updates are turned off but they are really turned on. I am getting quite frustrated because I've posted about this problem on some other sites and have not gotten any help so I'm hoping I can get the problem solved here. I've scanned my entire computer with AVG, McAfee, Malwarebytes Anti Malware, and Super Anti SpyWare and none of them are picking up anything.

Hello and welcome.. Lets start here and see the logs.
If both AVG and McAfee are running live ,one has to be turned off.

This infection changes settings on your computer so that when you launch an executable, a file ending with .exe, it will instead launch the infection rather than the desired program. To fix this we must first download a Registry file that will fix these changes. From a clean computer, please download the following file and save it to a removable media such as a CD/DVD, external Drive, or USB flash drive.

FixNCR.reg

insert the removable device into the infected computer and open the folder the drive letter associated with it. You should now see the FixNCR.reg file that you had downloaded onto it. Double-click on the FixNCR.reg file to fix the Registry on your infected computer.



Next run RKill....
Download and Run RKill
  • Please download RKill by Grinler from one of the 4 links below and save it to your desktop.

    Link 1
    Link 2
    Link 3
    Link 4

  • Before we begin, you should disable your anti-malware softwares you have installed so they do not interfere RKill running as some anti-malware softwares detect RKill as malicious. Please refer to this page if you are not sure how.
  • Double-click on Rkill on your desktop to run it. (If you are using Windows Vista, please right-click on it and select Run As Administrator)
  • A black screen will appear and then disappear. Please do not worry, that is normal. This means that the tool has been successfully executed.
  • If nothing happens or if the tool does not run, please let me know in your next reply

Do not reboot your computer after running rkill as the malware programs will start again. Or if rebooting is required run it again.

^^

If you get an alert that Rkill is "infected", ignore it. The alert is just a fake warning given by the rogue software which tries to terminate programs that try to remove it. If you see such a warning, leave the warning on the screen and then run Rkill again. By not closing the warning, this sometimes allows you to bypass the malware's attempt to protect itself so that Rkill can perform its routine.


Try this with RKill.... download iExplore.exe or eXplorer.exe, which are renamed copies of rkill.com, and try them instead.

Do not reboot your computer after running rkill as the malware programs will start again.

Rerun MBAM (MalwareBytes) like this:

Open MBAM in normal mode and click Update tab, select Check for Updates,when done
click Scanner tab,select Quick scan and scan (normal mode).
After scan click Remove Selected, Post new scan log and Reboot into normal mode.

Please ask any needed questions,post logs and Let us know how the PC is running now.

Ok. Firefox is working fine now and is no longer redirecting me to other sites. However, my computer still says my automatic updates are turned off but they are on.

Excellent!!
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. To learn more about this risk, please read:

Ok. Everything was working just fine yesterday but now, firefox and google chrome are running painfully slow again. I'm not having any issues with either browser freezing but some sites run quite slow and some pages take forever to load up. Everything is up to date, firewall and automatic updates are on, etc. I'm not sure why they're still running so slow.

I recommend clearing the entire cache to ensure everything is cleaned out:

Change your DNS Servers:
  • Go to Posted Image > Run... and in the open box, type: cmd
  • Press OK or Hit Enter.
  • At the command prompt, type or copy/paste: ipconfig /flushdns
  • Hit Enter.
  • You will get a confirmation that the flush was successful.
  • Close the command box.
