I can't access internet problem

Here it is. And about System restore, when that guy was installing my system (several years ago, back then I knew nothing abouth PCs), he disabled it, and I have no restore points now (I am felling so shamed now :)) ).

Those pings are rather high for a default gateway. You said that your connection worked in safe mode. Could you please follow this tutorial to trial and error what applications could be causing the issue. Please be advised that this is a pain and can be a long process however since there isn't a system restore point there is no other way of identifying what application is causing the issue

Troubleshoot Application Conflicts by Performing a Clean Startup

Make sure you uncheck any anti-virus software temporarily since this is a suspect as well

Also while you are troubleshooting could you please turn on system restore so that restore points are made. They do eat up Harddrive space but in desperate measures it can be a life saver and should never be turned off - System Restore Configuration - Enable or Disable

Hope This Helps,
Josh! :)

When I go to any site, in adress bar I get message that all cookies are blocked (screenshot), then when I go to 'Manage cookie blocking', this window pops out (screenshot), when I click to puzzle icon it shows me this box (screenshot), but I haven't any extension with similar icon (screenshot). Maybe this will help a little?

Thank you for providing that information. While it is possible for it to block the access it would not explain the other Browsers issue. As a process of elimination could you uncheck the 'Enabled' box on all extensions in Google Chrome and then test connectivity.

Many Thanks,
Josh! :)

I disabled all extensions and, as expected, no results (but cookies are not blocked any more), I tried Troubleshoot 'Application Conflicts by Performing a Clean Startup' but after first step I saw no results, and I stoped using that method (as said in tutorial). Now I suppose that problem is in programs that runs in Clean Startup, and don't runs in Safe Mode, if there are some. If there are no such programs, I'm afraid that maybe there is some kond of virus im my PC which antivirus programs can't recognize

. And thank you sooooo much for your help so fair :)

It is possible that a Virus could do this. Typically a clean boot won't disable the A/V however safe mode will. My only and last possible solution I can think of is that your Anti-Virus and firewall is causing this issue. What is your Anti-Virus? If you can could you temporarily uninstall this and then test? If it still doesn't work then the only other option I could suggest is a clean fresh install especially if you suspect your machine to have been compromised

I'm using AVG Internet Security 2012. Now I'm uninstalling it and then we will see what happens.

I uninstalled AVG, and and there was no changes, then I installed 'Malwarebytes Anti-Malware' and runned slow scan, it found some malware, I deleted it and reboot system, after that I ran scan again but it showed two infected files (sceenshot), I tried to delete it several times but i couldn't. Then I copied file location from log, but it couldn't find the file (screenshot of log, screenshot of error message). Then I tried to go to file location from Malwarebytes (screenshot) and it took me to Registry Editor (screenshot). Now I don't know what to do, any ideas? :)

Clean install I think

That is the only way you are going to know that your machine is free from malware. I can see if I can contact security specialist to try and help for you if you would like however there is no guarantee that it'll work.

For a clean install follow this tutorial - Clean Install Windows 7

Warning

Any personal files and programs will be erased upon a clean installation. Please backup your personal files before doing so

If you wish to backup your personal files I would follow this tutorial (I understand that you are able to boot into your machine however this method allows you to copy your personal files without the risk of copying any malware with it which could infect the new install) - Use Ubuntu Live CD to Backup Files from Your Dead Windows Computer

If you can make the disc on a different machine than the one suffering from the infection
