Good day. Let me start by letting you know that I have absolutely no computer expertise whatsoever - explanations of what to do will need to be simple. Sorry for what is going to be long posting, but I'd like to give complete background so that you can properly help me.

Yesterday I was on MySpace before noon ~ this is the only site I had visited that is out of the norm for me. I'm pretty boring and regular with what I visit...and I do not download or click 'yes' on just any old box that pops up. Having said that, I absolutely did not download anything yesterday until well after the problem first cropped up. My protection settings are medium-high, and I was running AVG 8.0 (free).

The problem: I began having trouble with some of my webpages freezing. It would seem to load, the little green bar at the bottom would be all green, I could see the web page, but the scroll bar would not move, neither the 'back' nor 'refresh' button would work, and I could not close or "x" out of IE. (I was using IE 7, my OS is Window XP, with Service Pack 3. I downloaded and am now using IE8.) In fact, I could do nothing at all except hit the power button on my laptop.

The first time I assumed it was the site I was visiting, so when I got back online I went to a different site. It seemed slow to me, as did several other sites, and then the same freezing thing happened on another site. This was the second time I had to power off and then power back on.

On the power on I noticed that a small window popped up. It was C:\Program Files\Common. The contents were: helper.dll and helper.sig. I had not seen this before and was concerned enough to google it. I found lots and lots of information, most of which I didn't understand. I understood enough to know that I had a problem and that it might be hard to fix.

Per some of the sites that I read, I downloaded Ad-Aware Free and ran it. It didn't find anything. (My AVG hadn't found anything either, even after I made sure it was updated.) I then downloaded Malwarebytes' Anti-Malware (free) and ran it. I kept a copy of the log it produced, showing me that I had 19 infected files - 15 of those are now in "Quarantine" and 4 were "deleted upon reboot". After the reboot, the "Common" folder was still on my C:drive; following a the advice of one the sites I had read earlier, I deleted the empty folder. (not the Common Files folder, just the Common folder) I ran a second Malwarebytes scan after deleting the folder and it found zero infected files.

I downloaded the Ad-Aware and the Malwarebytes through CNet. I also downloaded and ran HijackThis, keeping a copy of the log, because from my reading about this issue it seems that you might ask to see this info. I cleaned up my computer some by using "Add/remove" programs to remove items I was absolutely sure I could ~ extras that came with my computer that I had never used. I also just finished a "degrag" of my computer.

My concerns: Is it likely I'm still infected with something? Can I safely visint my banking and other password protected & sensitive information sites? What can I do to make sure this doesn't happen again? I thought I was safe by using AGV, but it never noticed anything. How often should I run the Ad-Aware and the Malwarebytes?

Many, many thanks for any information you can give me.

Sorry it took so long to reply...the scan took some time.

As far as how my laptop is running....it's fine now ~ haven't noticed any issues with slowness and no freezing. I'm just concerned about my passwords being stolen from this point forward. I am scared to go to my banking sites now.

No problem we all have other things to do.
Now 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.

I have done as you suggested - it was very quickly done.

Is there anything else I should do? Am I safe now?

Thank you very, very for your patient help ~ you directions are clear and precise. :thumbsup: I was very tempted to do this: :flowers: .... but I can't afford to! LOL.
