Here is screen shoot of my problem.

Any ideas how to fix that? It’s really anyoing (and scary). I don’t know what can it do to me.
If someone can give me instructions to try to remove that, whatever it is.
Attach your basic logs. (MBAM, FRST and aswMBR…!!)
Instructions: https://forum.avast.com/index.php?topic=53253.0
Monitoring.
Ok, I followed instructions, did MBAM, found something, applied fix for that, restarted computer, but still same problem on startup.
Then i did following 2 scans. Logs are attached here.
Good job, now wait for Valinorum, he’ll guide you.
Ok, thanks

Ok… What can I say…
Except that you are AMAZING!
Did as you instructed, pc rebooted, no more problem - problem SOLVED. Everything works fine and smooth.
I really appreciate for helping me and thank you ! If you could only see my face when i realised that there is no longer malware here:)
I attached Fixlog that you required.
And if i may ask you three questions related to this.
One more time,
Thank you very very much,
Best regards,
Gnulkciwtne.
Please, read the prevention part and see if it answers your queries. If you have questions, ask me. Perusing your logs, I see no infection currently present in your system. Unless you are having any issue(s), the machine appears to be Malware-free as we speak.
Removal of Tools and Quarantined Files
Despite the tools we have used are clean, they are powerful removal tools and made in a way so that they carry out any commands given to them without (most cases) asking for a confirmation. In the hands of an inept person, they can make the machine un-bootable – a scenario we do not wish to see. Also, we need to remove the quarantined files/folders from your system as a dormant malware can be as bad as an active one if given the proper environment. I shall now give you the guidelines to remove the tools and the quarantined files from your system.
[*]Cleanup with Delfix
Please download DelFix by Xplode to your Desktop.
Download Link
[*]Double-click to run the program;
[list][*]Note: Windows Vista/7/8 users right-click and choose Run as administrator[*]Make sure that all the boxes are checked;
[*]Click Run;
[*]A log will be opened after the operation is finished;
[*]Copy and Paste it in your next reply[/list]
Prevention and Future Guidelines
Prevention is better than cure – goes the old saying. As much as we love to see you visit our site, we do not want to see you having your PC infected by malwares again.
[*]Keep Windows up-to-date.
It is extremely important that you keep your operating system (Windows) updated when updates are made available. It is set to alert you, so be sure not to ignore these notices and to allow the updates to install. Many of these are critical security packages which could very possibly be the difference between your picking up a future infiltration and simply passing right by it unharmed.
[*]Run antivirus software and keep it up-to-date, too.
Antivirus software is your safety net if all other protections fail. The first line of defense is smart computing, of course, but everyone needs a backup. Once they’re installed, check periodically to ensure they have been successfully updating as well. An out-of-date antivirus is not a happy antivirus!
[*]Keep your web browser plugins and other programs updated also.
This tip is rarely shared by technicians and its importance is not widely recognized, but it’s absolutely critical. Programs such as Java, Adobe Flash Player and Adobe Reader, Internet Explorer, and myriad other such web-exposed items are deeply vulnerable to attack, which can quickly lead to a hopelessly infected system no matter what protection you currently have installed. The reason is that these programs are ubiquitous, but are also not perfect and are extremely complex… and as such, security vulnerabilities are discovered and exploited by hackers hoping to gain control over your machine. By performing every update for these programs as soon as it’s made available, you will greatly reduce your exposure to dangerous internet threats.
A great way to do this is to install the Filehippo Update Checker and run it regularly. Also, try not to ignore any notifications you receive regarding updates to programs already installed on your PC.
No scripts is an excellent security device too. I like it but it is not for everyone because it requires you to take action if you want to see some things (pop ups, banners etc.) on sites you visit.
Download NoSript by Giorgio Maone.
Note: Sometimes you will get a site telling you that you need to install Java when actually all you need to do is enable the site through the no script icon down on the right hand side of your computer.
[*]Watch out for new threat named CryptoLocker
CryptoLocker is a new type ransomware family malware that encrypts your important files and asks for a ransom to decrypt them. At the moment of posting this reply there are no tools that can undo the havoc this malware causes. We can help you to remove the malware from your system but the files that was encrypted cannot be recovered without the decryption key. So, I ask for your forbearance and practice constant vigilance. Please read the following article to acknowledge yourself about the safety measures.
How to prevent your computer from becoming infected by CryptoLocker.
[*]And last of all, surf smart.
It doesn’t matter how well the autopilot system works if the pilot keeps flying the plane into mountain ranges. Don’t forget that no matter how much you have protecting yourself, your security ultimately begins and ends with you. Don’t visit dangerous or questionable web sites, avoid suspicious links on Facebook and emails/email attachments you’re unsure about, and just generally keep your wits about you, and you’ll be much safer. Also, avoid illegal downloads, cracks, “warez”, and all other too-good-to-be-true internet offerings: they’re typically laden with malware. Be smart and you can avoid most threats lurking about the darker corners of the internet! And for even more tips, see our article, How Did I Get Infected in the First Place?

Ok, i carefully read your instructions to protect my self, and will do that, step by step.
Just that no-script plugin is designed for mozzila, and i’m using chrome, so i found a plugin named “ScriptSafe”.
I attached log that you requested, so you could see if everything is ok.
best regards,
Gnulkciwtne.
It will work too. Surf safely.
