Computer affetced with malware - not able to install anti-malware bytes software also

[B-boy/StyLe/]

Hello,

 

Can you please post the detection log from MBAM to see what was detected?

 

Thanks!

Hi Georgi,

 

Attaching the detection log file.

MBAM_detection.txt

[B-boy/StyLe/]

Hmmm,

 

That's weird because I tried to remove the folder with FRST earlier and FRST claimed that there is no such folder on your system:

 

"C:\Drivers" => File/Directory not found.

 

Please make sure that you can view all hidden files.  Instructions on how to do this can be found here:

How to see hidden files in Windows

 

and then let me know if you can see such a folder => c:\drivers ?

 

 

Regards,

Georgi

[sreedeep007]

Hi Georgi,

 

Yes indeed that folder is present which is a hidden folder that contains some personal data.

[B-boy/StyLe/]

Hi,

 

Try to delete it manually and let me know about the results.

HI Georgi,

 

Does the Security Log says this folder contains virus? This is my personal folder and have data which I cant delete. So what can be done?

[B-boy/StyLe/]

Hello,

 

That's weird because the folder is usually created by a KeyLogger. Also the folder was hidden as well.

And yes, regarding the MBAM log the folder contains a lot of malicious files inside:

What is happening if you allow MBAM to delete the malicious entries? From you detection log it's a bit unclear. Run a new Threat Scan with MBAM and let it quarantine the malicious entries.

Then run a new scan with it and see if MBAM found anything and let me know about the results.

Hi Georgi,

 

I have quarantined all the entries found by MBAM and ran the scan again and could see that no malicious entries exits.

Hello,

 

 

I think that additional actions are needed anymore.

 

And here are my final recommendations to you:

 

 

Nicely done ! This is the end of our journey if you don't have any more questions.

Thank you for following my instructions perfectly.
I have some final words for you.
All Clean !
Your machine appears to be clean, please take the time to read below on how to secure the machine and take the necessary steps to keep it Clean.

 

 

 

STEP 1 CLEANUP

 

 

 

To remove all of the tools we used and the files and folders they created, please do the following:

 

 

Click on Start => now type in start menu search box: ComboFix /Uninstall into the run-box and click OK.
Note the space between the X and the /Uninstall, it needs to be there.

 

 

 

Download the following file => fixlist.txt and save it to the Desktop.
NOTE. It's important that both files, FRST and fixlist.txt are in the same location or the fix will not work.

Run FRST/FRST64 and press the Fix button just once and wait.
It's no needed to post the log this time.

 

 

 

Please download OTC.exe by OldTimer and save it to your desktop.
 

• Right-click the OTC.exe and choose Run as Administrator.
• Click on CleanUp! button.
• If you are prompted to Reboot during the cleanup, select Yes.
• The tool will delete itself once it finishes.

 

• Next please download Delfix.exe by Xplode and save it to your desktop.
• Please start it and check the box next to "Remove disinfection tools" and click on the run button.
• The tool will delete itself once it finishes.

 

Note: If any tool, file, log file or folder (belonging to the program we have used) hasn't been deleted, please delete it manually.

 

 

 

STEP 2 SECURITY ADVICES
 

 

Change all your passwords !


Since your computer was infected for peace of mind, I would however advise you that all your passwords be changed immediately including those for bank accounts, credit cards and home loans, PIN codes etc)!! (just in case).

If you're storing password in the browser to access websites than they are non encrypted well (only if you use Firefox with master password protection activated provide better security). So I strongly recommend to change as much password as possible. Many of the modern malware samples have backdoor abilities and can steal confidential information from the compromised computer. Also you should check for any suspicious transactions if such occur. If you find out that you have been victim to fraud contact your bank or the appropriate institution for assistance.

Use different passwords for all your accounts. Also don't use easy passwords such as your favorite teams, bands or pets because this will allow people to guess your password.
You can use PC Tools Password Generator to create random passwords and then install an application like KeePass Password Safe to store them for easy access.If you do Online Banikng please read this article: Online Banking Protection Against Identity Theft

 

 

Keep your antivirus software turned on and up-to-date

 

• Make sure your antivirus software is turned on and up-to-date.
• New viruses come out every minute, so it is essential that you have the latest signatures for your antivirus program to provide you with the best possible protection from malicious software.
  Note:
• You should only have one antivirus installed at a time. Having more than one antivirus program installed at once is likely to cause conflicts and may well decrease your overall protection as well as impairing the performance of your PC.
• You should scan your computer with an AntiSpyware program like Malwarebytes' Anti-Malware on a regular basis just as you would an antivirus software.
• Be sure to check for and download any definition updates prior to performing a scan.
• Also keep in mind that MBAM is not a replacement for antivirus software, it is meant to complement the protection provided by a full antivirus product and is designed to detect the threats that are missed by most antivirus software.

 

 

Install HIPS based software if needed (or use Limited Account with UAC enabled)

 

I usually recommend to users to install HIPS based software but this type software is only effective in the right hands since it require from the users to take the right decisions.

 

HIPS based software controls what an application is allowed to do and not allowed to do.
It monitors what each application tries to do, how it use the internet and give you the ability to block any suspicious activity occurring on your computer.
In my opinion the best way to prevent an unknown malware from gaining access is to use some HIPS programs (like COMODO Firewall, PrivateFirewall, Online Armor etc.) to control the access rights of legitimate applications, although this would only be advisable for experienced users. (so if you don't feel comfortable using such software then you can skip this advice)

 

However, you should be aware though that (if you install Comodo Firewall and not the whole package Comodo Internet Security) this is not an replacement for a standard antivirus application. It's a great tool to add another layer of protection to your existent antivirus application. Also note that if you have an antivirus installed then you should install Comodo Firewall (and not Comodo Internet Security to avoid conflicts).

 

It takes some time and knowledge to configure it for individual purposes but once done, you should not have a problems with it.
There are so many reviews on YouTube and blogs about all these programs.
Keep in mind to choose carefully in order to avoid conflicts or instability caused by incompatible security programs.
Also having more than one "real-time" program can be a drain on your PC's efficiency so please refrain doing so.

More information about HIPS can be found here: What is Host Intrusion Prevention System (HIPS) and how does it work?

 

If you like Comodo you should choose for yourself which version of Comodo you will use 5 or 7. Personally I stick to version 5 at least for now.

 

If these kind of programs are difficult for you to use then you can use limited user account (LUA) with UAC enabled. If you need administrative privileges to perform some tasks, then you can use Run As or log on as the administrator account for that specific task.

 

 

Be prepared for CryptoLocker:

 

 

CryptoLocker Ransomware Information Guide and FAQ

Since the prevention is better than cure you can use gpedit built-in Windows or CryptoPrevent (described in the first link) to secure the PC against this locker.

Another way is to use Comodo Firewall and to add all local disks to Protected Files and Folders

You may want to check HitmanPro.Alert.CryptoGuard and add install it to be safe when surfing the net.

 

 

Practice Safe Internet


One of the main reasons people get infected in the first place is that they are not practicing Safe Internet. You practice Safe Internet when you educate yourself on how to properly use the Internet through the use of security tools and good practice. Knowing how you can get infected and what types of files and sites to avoid will be the most crucial step in keeping your computer malware free. The reality is that the majority of people who are infected with malware are ones who click on things they shouldn't be clicking on. Whether these things are files or sites it doesn't really matter. If something is out to get you, and you click on it, it most likely will.  Below are a list of simple precautions to take to keep your computer clean and running securely:
 

• If you receive an attachment from someone you do not know, DO NOT OPEN IT! Simple as that.  Opening attachments from people you do not know is a very common method for viruses or worms to infect your computer.
• .exe, .com, .bat, .pif, .scr or .cmd do not open the attachment unless you know for a fact that it is clean.  For the casual computer user, you will almost never receive a valid attachment of this type.
• If you receive an attachment from someone you know, and it looks suspicious, then it probably is.  The email could be from someone you know infected with a malware that is trying to infect everyone in their address book.
• If you are browsing the Internet and a popup appears saying that you are infected, ignore it!. These are, as far as I am concerned, scams that are being used to scare you into purchasing a piece of software. For an example of these types of popups, or Foistware, you should read this article:
  Foistware, And how to avoid it. There are also programs that disguise themselves as Anti-Spyware or security products but are instead scams.  For a list of these types of programs we recommend you visit this link: About Malwares, Rogues, Scarewares, SmitfraudFix
• Another tactic to fool you on the web is when a site displays a popup that looks like a normal Windows message  or alert. When you click on them, though, they instead bring you to another site that is trying to push a product on you.  We suggest that you close these windows by clicking on the X instead of the OK button. Alternatively, you can check to see if it's a real alert by right-clicking on the window.  If there is a menu that comes up saying Add to Favorites... you know it's a fake.
• Do not go to adult sites. I know this may bother some of you, but the fact is that a large amount of malware is pushed through these types of sites. I am not saying all adult sites do this, but a lot do.
• When using an Instant Messaging program be cautious about clicking on links people send to you. It is not uncommon for infections to send a message to everyone in the infected person's contact list that contains a link to an infection. Instead when you receive a message that contains a link, message back to the person asking if it is legit before you click on it.
• Stay away from Warez and Crack sites! In addition to the obvious copyright issues, the downloads from these sites are typically overrun with infections. Avoid using cracks and unknown programs from sources you don't trust. There are MANY alternative open-source applications. Malware writers just love cracks and keygens, and will often attach malicious code into them. By using cracks and/or keygens, you are asking for problems. So my advice is - stay away from them!
• Be careful of what you download off of web sites and Peer-2-Peer networks. Some sites disguise malware as legitimate software to trick you into installing them and Peer-2-Peer networks are crawling with it. If you want to download a piece of software a from a site, and are not sure if they are legitimate, you can use McAfee Siteadvisor to look up info on the site. Note: skip this advice if your antivirus have a Web Guard.
• DO NOT INSTALL any software without first reading the End User License Agreement, otherwise known as the EULA. A tactic that some developers use is to offer their software for free, but have spyware and other programs you do not want bundled with it. This is where they make their money. By reading the agreement there is a good chance you can spot this and not install the software.

 

 

Tweak your browsers
 
 
MOZILLA FIREFOX


To prevent further infections be sure to install the following add-ons NoScript and AdBlock Plus

 

Adblock Plus hides all those annoying (and potentially dangerous) advertisements on websites that try and tempt you to buy or download something. AdBlock not only speeds up your browsing and makes it easier on your eyes, but also makes it safer.

 

Adblock Plus can be found here.

 

NoScript is only for advanced users as it blocks all the interactive parts of a webpage, such as login options. Obviously you wouldn’t want to block your ability to log on to your internet banking or your webmail, but thankfully you can tell NoScript to allow certain websites and block others. This is very useful to ensure that the website you’re visiting is not trying to tempt you to interact with another, more dangerous website.

 

NoScript can be found here
 

 

Google Chrome

 
If you like Google Chrome there are many similar extensions for this browser as well. Since I am not a Google Chrome user I can't tell you which of them are good and how they work. You should find out by yourself.

However Google Chrome can block a lot of unknown malware because of his sandbox.Beware of the fact that Google Chrome doesn't provide master password protection for your saved in the browser passwords. Check this out: Google Chrome security flaw offers unrestricted password access

 

 

For Internet Explorer 9/10 read the articles below:
 

Security and privacy features in Internet Explorer 9

Enhanced Protected Mode
Use Tracking Protection in Internet Explorer

Security in Internet Explorer 10

 

Immunize your browsers with SpywareBlaster 5 and Spybot Search and Destroy 1.6

Also MBAM acquired the following software Malwarebytes Anti-Exploit and it should work with the most popular browsers. Beware the product is in beta stage.

Changelog can be seen here and known issues here.

 

 
Make the extensions for known file types visible:
 

Be wary of files with a double extension such as jpg.exe. As a default setting, Windows often hides common file extensions, meaning that a program like image.jpg.exe will appear to you as simply image.jpg. Double extensions exploit this by hiding the second, dangerous extension and reassuring you with the first one.Check this out - Show or hide file name extensions.

 

 

Disable Autorun:

 

It's a good idea to disable the autorun functionality using the following tool to prevent spreading of the infections from USB flash drives.

 

 

Create an image of your system (you can use the built-in Windows software as well if you prefer)

 

• Now when your pc is malware free it is a good idea to do a backup of all important files just in case something happens it.
• Macrium Reflect is very good choice that enables you to create an image of your system drive which can be restored in case of problems.
• The download link is here.
• The tutorial on how to create an system image can be found here.
• The tutorial on how to restore an system image can be found here.
• Be sure to read the tutorial first.

 

 

Follow this list and your potential for being infected again will reduce dramatically.

Safe Surfing!
