Hi everyone, this is my first post and I'm desperate, here. I think I'm infected with Malware and I can't find it or get it out! I have screen shotes of the two "ads" that are showing up, if someone wants to see them. Clearly they are designed to get you to try and click on them. They are both showing up all across the web when I visit other pages, too.
 

Here is what I've done, scans I've run:

CCleaner
Advance System Care
Spybot Search and Destroy
Super Antispyware
MalwareBytes
AVG Virus Scan
And maybe one or two more (I can't remember)

None of these are picking up anything.

I've done a system restore to the earliest point I could, and that didn't remove it.

I have a couple of programs that I tried to uninstall, but are still showing up in my programs too. I suspect they are malicious. I think I got them when I was streaming videos from a site I thought was safe.

Also, when I log in through my son's desktop and use either Firefox or IE, they don't show up. When I log in through my desktop and use IE they don't show up, but when I use Firefox, they do. I also created another user desktop and they tried through there and they don't show up on that new desktop, either.
 

I have also noticed that there are two files showing up on C: that seem strange.
 

Computer>OS (C:)>Program Files -- (which I've always noticed) and
Computer>OS (C:)>Program Files (x86) -- (which struck me as odd)

 

Any ideas? I don't want to have to take it in, but am afraid I might have to. I can't be without this computer for very long since I work at home.

 

Thanks, in advance, for any input you might have.
Julie

Welcome aboard p22002758.gif

 

If Firefox is the only program affected the fastest way to fix the issue would be to uninstall Firefox completely using this guide: http://kb.mozillazine.org/Uninstalling_Firefox and install fresh copy.

 

Also, uninstall Advance System Care.

Registry cleaners/optimizers are not recommended for several reasons:

  • Registry cleaners are extremely powerful applications that can damage the registry by using aggressive cleaning routines and cause your computer to become unbootable.

    The Windows registry is a central repository (database) for storing configuration data, user settings and machine-dependent settings, and options for the operating system. It contains information and settings for all hardware, software, users, and preferences. Whenever a user makes changes to settings, file associations, system policies, or installed software, the changes are reflected and stored in this repository. The registry is a crucial component because it is where Windows "remembers" all this information, how it works together, how Windows boots the system and what files it uses when it does. The registry is also a vulnerable subsystem, in that relatively small changes done incorrectly can render the system inoperable. For a more detailed explanation, read Understanding The Registry.
  • Not all registry cleaners are created equal. There are a number of them available but they do not all work entirely the same way. Each vendor uses different criteria as to what constitutes a "bad entry". One cleaner may find entries on your system that will not cause problems when removed, another may not find the same entries, and still another may want to remove entries required for a program to work.
  • Not all registry cleaners create a backup of the registry before making changes.  If the changes prevent the system from booting up, then there is no backup available to restore it in order to regain functionality. A backup of the registry is essential BEFORE making any changes to the registry.
  • Improperly removing registry entries can hamper malware disinfection and make the removal process more difficult if your computer becomes infected. For example, removing malware related registry entries before the infection is properly identified can contribute to system instability and even make the malware undetectable to removal tools.
  • The usefulness of cleaning the registry is highly overrated and can be dangerous. In most cases, using a cleaner to remove obsolete, invalid, and erroneous entries does not affect system performance but it can result in "unpredictable results".

Unless you have a particular problem that requires a registry edit to correct it, I would suggest you leave the registry alone. Using registry cleaning tools unnecessarily or incorrectly could lead to disastrous effects on your operating system such as preventing it from ever starting again. For routine use, the benefits to your computer are negligible while the potential risks are great.

Thanks! I'll try uninstalling/reinstalling Firefox now. I didn't realize that just a brower can be infected. I will also uninstall the Advance System Care. I appreciate the help. I will be back with an update. :)

If you have any pop-ups or ads while NOT using Firefox let me know and we'll run some more checks.

That seems to have done it. They are no longer showing up as I browse the net. I currently run AVG (free version). I haven't had a problem like this before now. Is it a good program? Is there something else I should use? How can I avoid this happening again in the future?

 

Thanks, again!
Julie

You have to be careful what you're installing.

AVG is fine.
