Well like the title explains my internet just stops working every few minutes and then magicly fixes itself en works just fine, only to be repeated. I did get a message from AVG that I got 3 trojan virusses after some obscure download but it said it removed them all. When I did a full, slow scan of the entire computer all it could find were some tracking cookies. The same when I tried Ad-Aware. These are the only virus and spyware scanners I have by the way (all the free versions). I also have ZoneAlarm. When I run a connection test with MSN messenger it tells me there's a problem with my DNS, it can't resolve IP-adresses. If I try again a random amount of time later it's fixed.
Does anyone have any idea what's causing this?

***UPDATE***
I installed Spybot - search and destroy and ran a scan. It found some malware and spyware and successfully removed it all but no improvement in the problem.

Please download Malwarebytes Anti-Malware (v1.39) and save it to your desktop.
alternate download link 1
alternate download link 2

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

-- If Malwarebytes Anti-Malware results in any error messages, please refer to Fixes for common problems and Error Codes. Some issues with errors can be related to malware infection but others are not.

-- Some types of malware will disable Malwarebytes Anti-Malware and other security tools. If MBAM will not install, try renaming it first.
  • Right-click on the mbam-setup.exe file file and rename it to mysetup.exe.
  • Double-click on mysetup.exe to start the installation.
  • If that did not work, then try renaming and changing the file extension. <- click this link if you do not see the file extension
  • Right-click on the mbam-setup.exe file, rename it to mysetup and change the .exe extension to .scr, .com, .pif, or .bat.
  • Then double-click on mysetup.scr (or whatever extension you renamed it) to begin installation.
If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files.
  • Right-click on mbam.exe, rename it to myscan.exe.
  • Double-click on myscan.exe to launch the program.
  • If that did not work, then try renaming and change the .exe extension in the same way as noted above.
  • Double-click on myscan.scr (or whatever extension you renamed it) to launch the program.
If using Windows Vista, refer to How to Change a File Extension in Windows Vista.

Now rescan again with Malwarebytes Anti-Malware but this time perform a Full Scan in normal mode and check all items found for removal. Don't forgot to check for database definition updates through the program's interface (preferable method) before scanning and to reboot afterwards. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. When done, click the Logs tab and copy/paste the contents of the new report in your next reply.

Please download and scan with Dr.Web CureIt - alternate download link.
Follow these instructions for performing a scan in "safe mode".
If you cannot boot into safe mode or complete a scan, then try doing it in normal mode. Be aware, this scan could take a long time to complete.
-- Post the log in your next reply. If you can't find the log, try to write down what was detected/removed before exiting Dr.WebCureIt so you can provide that information.

Malwarebytes Anti-Malware couldn't find anything as stated in the log but Dr.Web CureIt did. It found and removed 2 trojan horses which probably were the problem since I'm having a stable connection for a while now. One more question, should I remove some of the programs like Malwarebytes and Dr.Web CureIt because they might interfere or would you advice me to keep them?
Here's the log:

I would keep and continue to use MBAM. I recommend taking advantage of the Malwarebytes Anti-Malware Protection Module which uses advanced heuristic scanning technology to monitor your system and provide real-time protection to prevent the installation of most new malware. This technology monitors every process and stops malicious processes before they can infect your computer. The database that defines the heuristics is updated as often as there is something to add to it. Enabling the Protection Module feature requires reqistration and purchase of a license key that includes free lifetime upgrades and support. After activation, Malwarebytes can be set to update itself and schedule scans automatically on a daily basis. The Protection Module is not intrusive as it utilizes few system resources and should not conflict with other scanners or anti-virus programs.

Dr.Web CureIt is frequently updated and can always be downloaded again to use as a stand-alone scanner.

Please download Rooter.exe and save to your desktop.
alternate download link
  • Double-click on Rooter.exe to start the tool. If using Vista, right-click and Run as Administrator...
  • Click the Scan button to begin.
  • Once the scan is complete, Notepad will open with a report named Rooter_#.txt (where # is the number assigned to the report).
  • A folder will be created at the %systemdrive% (usually, C:\Rooter$) where the log will be saved.
  • Rooter will automatically close. If it doesn't, just press the Close button.
  • Copy and paste the contents of Rooter_#.txt in your next reply.
Important: Before performing an ARK scan: Before performing an ARK scan it is recommended to do the following to ensure more accurate results and avoid common issues that may cause false detections.
  • Disconnect from the Internet or physically unplug you Internet cable connection.
  • Clean out your temporary files.
  • Close all open programs, scheduling/updating tasks and background processes that might activate during the scan including the screensaver.
  • Temporarily disable your anti-virus and real-time anti-spyware protection.
  • After starting the scan, do not use the computer until the scan has completed.
  • When finished, re-enable your anti-virus/anti-malware (or reboot) and then you can reconnect to the Internet.

You're welcome.

If there are no more problems or signs of infection, you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been backed up, renamed and saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista users can refer to these links: Create a New Restore Point in Vista and Disk Cleanup in Vista.

Tips to protect yourself against malware and reduce the potential for re-infection:Ľ Keep Windows and Internet Explorer current with all critical updates from Microsoft which will patch many of the security holes through which attackers can gain access to your computer. If you're not sure how to do this, see Microsoft Update helps keep your computer current.

Ľ Avoid gaming sites, porn 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 sm÷rgňsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Malicious worms, backdoor Trojans IRCBots, and rootkits spread across P2P file sharing networks, gaming, porn and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and malicious Flash ads that install viruses, Trojans, and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users. The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications.Ľ Keeping Autorun enabled on USB (pen, thumb, jump) and other removable drives has become a significant security risk due to the increasing number of malware variants that can infect them and transfer the infection to your computer. To learn more about this risk, please read:Many security experts recommend you disable Autorun asap as a method of prevention. Microsoft recommends doing the same.

...Disabling Autorun functionality can help protect customers from attack vectors that involve the execution of arbitrary code by Autorun when inserting a CD-ROM device, USB device, network shares, or other media containing a file system with an Autorun.inf file...

Microsoft Security Advisory (967940): Update for Windows Autorun
