Hello MHutch,

 

hope you had a good weekend.

 

Yes, it was a good one. Thank you for asking. That was very kind of your part. I hope that you had a nice weekend too! :)

 

I also sent you 20 Euros via PayPal - Thanks for all your help.

 

Thank you and cheers! beer11.gif
 

 

Here is the Checkup Log - not sure why it still says Java is not up to date.

 

Don't worry. This is a glitch in SecurityCheck. An update of the tool should fix it.

 

 

Before I let you go I'd like to scan your machine with ESET OnlineScan
 

  • Please download and the run exe from the link below:
    ESET OnlineScan
  • Check esetAcceptTerms.png
  • Click the esetStart.png button.
  • Accept any security warnings from your browser.
  • Check the option beside: Enable detection of potentially unwanted applications
  • Now click on Advanced Settings and make sure that the option Remove found threats is NOT checked, and select the following:
    • Scan archives
    • Scan for potentially unsafe applications
    • Enable Anti-Stealth Technology
    • Click on the Change button and select only Operating memory and drive C:\

fhSji42.png

 

  • Push the Start button.
  • ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
  • When the scan completes, push esetListThreats.png
  • Push esetExport.png, and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
  • Push the esetBack.png button.
  • Push esetFinish.png

 

Let me know for any remaining issues.

 

 

Regards,

Georgi

Nicely done Mark ! :bananas: This is the end of our journey if you don't have any more questions.
Thank you for following my instructions perfectly. smile.png
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:

 

  • 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...then you can add Secure Login to prevent Java and other exploits when log-in.

 

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 Password Generator - Norton Identity Safe 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

 

  • Install an antivirus program of your choice and make sure that you keep it updated
  • 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.
  • Note: You should scan your computer with an antimalware 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.

 

 

Be prepared for CryptoLocker and similar threats:
 

 

The ascension of Crypto-Ransomware and what you need to know to protect yourself

 

 

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 these lockers.

 

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.

 

It's a good idea to have Sandboxie installed and to run your browser inside a sandbox.

 

You may want to check Malwarebytes Anti-Exploit and add install it to be safe when surfing the net. It work with the most popular browsers and it is very effective. See the article here.

 

HitmanPro.Alert.CryptoGuard provides similar protection but it failed in the latest test here. However the tool is still under development and will be improved a lot in the future so you can keep an eye on it and its progress.

 

Note: However keep in mind that HitmanPro.Alert is not fully compatible with Malwarebytes' Anti-Exploit and you should choose only one between both of them.

 

EMET is another great tool which should lock the computer against exploits but it can be too confusing to use for home users. However you can take a look at it if you want.
 
Remember that having more than one "real-time" 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.

 

If these kind of programs are difficult for you to use then you can use a standard user account 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.

 

 

 

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, .cmd or .vbs 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.
  • You may want to install unchecky to prevent adware bundled into many free programs to install.

 

 

Tweak your browsers
 

MOZILLA FIREFOX

 

To prevent further infections be sure to install the following add-ons 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.
 
Do not add to many filters subscriptions because it will slow down your browser startup time.

You can take a look at NoScript as well but 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.

 

You can download it from here
You can find the optimal settings here
A tutorial on how to use it can be found here

 

 

Ad-Muncher is now free so you can give it a try as well.

 

 

 

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 9/10/11 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 MVPS HOSTS.

Also you can change your DNS settings 8.26.56.26 and 8.20.247.20 to use Comodo Secure DNS for free (to prevent phishing attacks). Sometime the DNS servers may be overloaded by the traffic coming from other networks and then you will lose internet connection. Then you can switch back to your ISP DNS settings again or to try other services like OpenDNS

 

 

 

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 and Windows Scripting Host:
 
 
It's a good idea to disable the Autorun functionality using the following tool to prevent spreading of the infections from USB flash drives.

 

If you don't use any script files then you can go ahead and disable Windows Scripting Host using the tool provided by Symantec - NoScript.exe. Simple download and run it and click on the Disable button and reboot the computer. If you need to run any js. or vbs scripts at a later stage you should run NoScript again and select Enable, then reboot the computer.
 

 

 
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 ! :)

 

Regards,

Georgi
