Hi,I am getting messages from my anti-virus software to tell me that ''A recent attempt to attack my computer has been blocked'
These messages occur randomly when my web browser is online or sometimes offline.
The problem is my browser sometimes slows down, or stops working altogether and will not access any websites or reconnect.Also, there seems to be constant activity on my hard disc, even when my computer is idle.
Recently when I used ''netstat''I detected 2 ports open when I was not using the Internet.
I am running Windows Vista Home Premium edition.Service Pack 2
My Antivirus software is Nortons 360
Processor AMD Athlon and 2 GB Ram
I woulld appreciate any help.
best regards ''midigame''

Please download TFC (Temp File Cleaner) by Old Timer and save it to your desktop.
alternate download link
  • Save any unsaved work. TFC will close ALL open programs including your browser!
  • Double-click on TFC.exe to run it. If you are using Vista, right-click on the file and choose Run As Administrator.
  • Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
  • TFC will clear out all temp folders for all user accounts (temp, IE temp, Java, FF, Opera, Chrome, Safari), including Administrator, All Users, LocalService, NetworkService, and any other accounts in the user folder.
  • Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.
Note: It is normal for the computer to be slow to boot after running TFC cleaner the first time.

Please download Malwarebytes Anti-Malware (v1.46) and save it to your desktop.Download Link 1

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.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • 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.Please download Norman Malware Cleaner and save to your desktop.
alternate download link
  • Be sure to read all the information Norman provides on the same page.
  • Double-click on Norman_Malware_Cleaner.exe to start the program.
  • Read the End User License Agreement and click the Accept button to open the scanning window.
  • Click Start Scan to begin.
  • In some cases Norman Malware Cleaner may require that you restart the computer to completely remove an infection. If prompted, reboot and run the tool again to ensure that all infections are removed.
  • After the scan has finished, a log file a log file named NFix_date_time (i.e. NFix_2009-06-22_07-08-56.log) will be created on your desktop with the results.
  • Copy and paste the contents of that file in your next reply.
Note: For usb flash drives and/or other removable drives to scan, use the Add button to browse to the drives location, click on the drive to highlight and choose Ok.

Please perform a scan with Kaspersky Online Virus Scanner.
-- Requires free Java Runtime Environment (JRE) to be installed before scanning for malware as ActiveX is no longer being used.
-- This scan will not remove any detected file threats but it will show where they are located so they can be cleaned with other tools.
  • Vista users need to right-click the IE or FF Start Menu or Quick Launch Bar icons and Run As Administrator from the context menu.
  • Read the "Advantages - Requirements and Limitations" then press the Posted Image... button.
  • You will be prompted to install an application from Kaspersky. Click the Run button. It will start downloading and installing the scanner and virus definitions.
  • When the downloads have finished, you should see 'Database is updated. Ready to scan'. Click on the Posted Image... button.
  • Make sure these boxes are checked. By default, they should be. If not, please check them and click on the Posted Image... button afterwards:
    • Detect malicious programs of the following categories:
      Viruses, Worms, Trojan Horses, Rootkits
      Spyware, Adware, Dialers and other potentially dangerous programs
    • Scan compound files (doesn't apply to the File scan area):
      Archives
      Mail databases
  • Click on My Computer under the Scan section. OK any warnings from your protection programs.
  • The scan will take a while so be patient and do NOT use the computer while the scan is running. Keep all other programs and windows closed.
  • Once the scan is complete (the 'status' will show complete), click on View Scan Report and any infected objects will be shown.
  • Click on Save Report As... and change the Files of type to Text file (.txt)
  • Name the file KAVScan_ddmmyy (day, month, year) before clicking on the Save button and save it to your Desktop.
  • Copy and paste (Ctrl+C) the saved scan results from that file in your next reply.
-- Note: Some online scanners will detect existing anti-virus software and refuse to cooperate. You may have to disable the real-time protection components of your existing anti-virus and try running the scan again. If you do this, remember to turn them back on after you are finished.

It is not unusual for a firewall and similar security suites to provide numerous alerts regarding such attempted access. Botnets and Zombie computers scour the net, randomly scanning a block of IP addresses, searching for vulnerable ports - commonly probed ports and make repeated attempts to access them. Your firewall is doing its job by blocking this kind of traffic and alerting you about these intrusion attempts. However, not all unrequested traffic is malevolent. Even your ISP will send out regular checks to see if your computer is still there, so you may need to investigate an attempted intrusion. If your computer is sending out large amounts of data, that can indicate that your system may have a virus or a Trojan.

To check whether or not the port in question is open on your system you can use netstat from a command prompt to obtain Local/Foreign Addresses, PID and listening state.
  • netstat /? lists all available parameters that can be used.
  • netstat -a lists all active TCP connections and the TCP and UDP ports on which the computer is listening.
  • netstat -b lists all active TCP connections, Foreign Address, State and process ID (PID) for each connection.
  • netstat -n lists active TCP connections. Addresses and port numbers are expressed numerically and no attempt is made to determine names.
  • netstat -o lists active TCP connections and includes the process ID (PID) for each connection. You can find the application based on the PID on the Processes tab in Windows Task Manager. This parameter can be combined with -a, -n, and -p (example: netstat -ano).
You can use Process Monitor, an advanced monitoring tool for Windows that shows real-time file system, Registry and process/thread activity or various network traffic monitoring tools for troubleshooting and malware investigation.

Online Port Scan allows you to scan individual TCP ports to determine if the device is listening on that port. Shields Up is an online port scanning service used to alert the users of any ports that have been opened through firewalls or NAT routers. There are third party utilities that will allow you to manage, block, and view detailed listings of all TCP and UDP endpoints on your system, including local/remote addresses, state of TCP connections and the process that opened the port:Caution: If you're going to start blocking ports, be careful which ones you block or you may lose Internet connectivity. For a list of TCP/UDP ports and notes about them, please refer to:You can investigate IP addresses and gather additional information at:
