Hi there,
my name is Marius and I will assist you with your malware related problems.

Before we move on, please read the following points carefully.

  • First, read my instructions completely. If there is anything that you do not understand kindly ask before proceeding.
  • Perform everything in the correct order. Sometimes one step requires the previous one.
  • If you have any problems while following my instructions, Stop there and tell me the exact nature of your problem.
  • Do not run any other scans without instruction or add/remove software unless I tell you to do so. This would change the output of our tools and could be confusing for me.
  • Post all logfiles as a reply rather than as an attachment unless I specifically ask you. If you can not post all logfiles in one reply, feel free to use more posts.
  • If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.
  • Stay with me. I will give you some advice about prevention after the cleanup process. Absence of symptoms does not always mean the computer is clean.
  • My first language is not english. So please do not use slang or idioms. It could be hard for me to read. Thanks for your understanding.

 
 
 
Scan with aswMBR

Please download aswMBR ( 4.5MB ) to your desktop.
  • Double click the aswMBR.exe icon, and click Run.
  • There will be a short delay before the next dialog box comes up. Please just wait a minute or two.
  • When asked if you'd like to "download the latest Avast! virus definitions", click Yes.
  • Typically this is about a 100MB download so depending on your connection speed it can take a short while to download and become ready.
  • Click the Scan button to start the scan once the update has finished downloading
  • On completion of the scan, click the save log button, save it to your desktop, then copy and paste it in your next reply.


Note: There will also be a file on your desktop named MBR.dat do not delete this for now. It is an actual backup of the MBR (master boot record).

Recommendations: How to protect yourself

  • System Updates
    Please ensure to have automatic updates activated in your control panel.
    For further information and a tutorial, see this Microsoft Support article.
  • Protection
    What you need is one (not more) virus scanner with background protection. Additionally I recommend a special malware scanner to run on demand weekly.
    Personally I am using avast! Antivirus Free Edition and Malwarebytes Anti-Malware. They offer good protection for free.
    • To keep your browser free of advertising, you may install the Adblock Plus browser extension.
      It will filter unwanted advertising out of the website´s content.
    • To protect yourself from accidentally visiting malicious web sites, install the Web of Trust (WOT) browser extension.
      It will display a green (safe), yellow (unknown) or red (potentially dangerous) icon for a visited website within your browser.
      In addition, before accessing a dangerous classified web site, a warning screen is displayed.

    [*]Up to date Software
    Keep your Windows and your third party software up to date. The easiest way to get infected is an outdated windows, followed by: browser(s) (including add-ons and plug-ins), Adobe Flash Player and Adobe Reader, Java Runtime Environment, your antivirus program and so on. These links may help you to check:

    [*]Backup
    Hardware issues, malware, fire, lightning strike: There is a long list of different ways to loose all your data. Back up your files regularly. Use the windows internal backup function or a third party tool and save your data onto an external hard drive, cloud storage, optical media like CDs or DVDs or (if available) a professional network backup system. [*]Behaviour
    The commonest error when using a computer is "error 80" - what means that the error is located about 80cm in front of the monitor. This is a common joke between IT support technicians but it shows that all the safety mechanisms won´t help if you aren´t careful enough.

    • While surfing the internet, don´t click on anything you don´t know. In the worst case, it infects your system with malware.
    • Watch your step in social networks! Many cyber criminals use them to spread malware, mine personal pata (to be sold to advertising companies, for example) or simply do damage to other users. Even if a received hyperlink within a message seems to be coming from one of your friends, have a closer look. In addition, don´t click everything.
    • When installing software, have a look to each of the setup windows and uncheck any additional toolbars or free programs that may be offered additionally. Most of today´s setup procedures contain potentially unwanted programs so keep them off your system.
    • 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 wide variety 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.
