hi. i have windows xp professional service pack 3 on my laptop. i have AT&T wireless internet. i continually get popups from norton antivirus (the newest one) concerning "an intrusion attempt by such & such ip address was blocked". i have researched the code of the os attack & it was cve-2008-4250. after further researching that code, i found that it was the w32 conficker worm. however, after using bit defender (full system scan), norton antivirus (full system scan), norton erase tool, & the w32 worm removal tool, none of those came up with anything. there were no threats on my computer, including no worms. now, the popups come up every so minutes now. i'm ready to pull my hair out. what else can i do if there is no worm? if i reinstall windows, will i receive these popups from my internet all over again? i prefer not reinstalling windows unless it has to be done. any help would be absolutely wonderful. thank you!

Hello, what is the pop up saying exactly.nay just be NAV doing it's job or even a False Positive.
What is your Operating System?

This may be a buried rootkit,

Please download Rootkit Unhooker from one of the following links and save it to your desktop.
Link 1 (.exe file)
Link 2 (zipped file)
Link 3 (.rar file)In order to use this tool if you downloaded from either of the second two links, you will need to extract the RKUnhookerLE.exe file using a program capable of extracing ZIP and RAR compressed files. If you don't have an extraction program, you can downlaod, install and use the free 7-zip utility.

  • Double-click on RKUnhookerLE.exe to start the program.
    Vista/Windows 7 users right-click and select Run As Administrator.
  • Click the Report tab, then click Scan.
  • Check Drivers, Stealth, and uncheck the rest.
  • Click OK.
  • Wait until it's finished and then go to File > Save Report.
  • Save the report to your Desktop.
  • Copy and paste the contents of the report into your next reply.
-- Note: You may get this warning...just ignore it, click OK and continue: "Rootkit Unhooker has detected a parasite inside itself! It is recommended to remove parasite, okay?".

. i continually get popups from norton antivirus (the newest one) concerning "an intrusion attempt by such & such ip address was blocked"

By that I take it you mean Norton Internet Security which includes firewall protection.

If your firewall provides an alert which indicates it has blocked access to a port or detected an intrusion attempt that does not necessarily mean your system has been compromised. These alert messages are a response to unrequested traffic from remote computers (an external host) to access a port on your computer.
Alerts are often classified by the network port they arrive on, and they allow the firewall to notify you in various ways about possible penetration and intrusion attempts on your computer. Even if the port is open, the alert message indicates that your firewall has blocked the attempt to access it.What are TCP and UDP ports
TCP/UDP Ports Explained
It is not unusual for a firewall and some anti-virus programs to provide numerous alerts regarding probing and intrustion attempts to access your computer. 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. Hackers use "port scanning", a popular reconnaissance technique, to search for vulnerable computers with open ports using IP addresses or a group of random IP address ranges so they can break in and install malicious programs. 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 Trojan. For more information about Port Scanning, please refer to Port Scanning Basic Techniques.

If the alerts become too annoying, you should be able to go into your firewall/anti-virus settings and lower or turn them off (Hide notification messages)
