How To Restore Network And LAN Configuration After Virus Infection
Dec 12, 2012
Some times I have got any computer thats infected by some virus and internet is not working. Booting Linux, Internet is working, but in Windows it is not. I am sure its virus problem, because IP, and others adjust are OK. Sometimes after scanning Windows with some antivirus system, internet works, but sometimes it doesnot. Well, is there any way to restore and repair damage caused by some virus or windows crushed, that are affected Internet? Now I have a computer that only things is affected is internet conexion. It doesnot work.
I repeate, is not a problem with LAN card, IP adress, so on..

My computer had a nasty virus which I think have since removed. The only problem is none of the programs in my program files are available. The folders are empty.I am at a bit of a loss here.If I search, I can find the programs so I know they are there somewhere!I am almost to the point where I want to scrub the hard drive and start from scratch. If I do this, how can I backup my program files that I have?Is there a way to drop them onto a back up hard drive, then just move them to the new fresh O.S.

Right about the time we got the virus out I started to get regular system freezes and BSODs at random times throughout the day. I'm not sure if it's something we did, if the virus messed something up, or if it's some unrelated issue. It's not the memory since I tested it last night and there weren't any errors.It can happen at any time. I haven't been playing any games and the only game I ever do play on this laptop is minecraft. I do play some Hulu and Netflix videos, but these crashes and lockups don't only occur when I'm watching a video. I can simply be browsing the web or working on my webpage and I will get the BSOD or the system will freeze.[CODE]

I have reformatted and installed a minimal version of Windows 7 but have yet to stop this thing from maintaining its hold on my network. After some 20 hours a day for nearly a month, it has taken its toll on my family. My son's new laptop for Xmas is now infected too. We will fix that very soon tho. Please guide me on how to proceed with this laptop for now. They have already wiped out my bank account once.

A client of mine (I'm an IT summer temp in a production facility) recently contracted the Windows 7 Recovery virus and contacted me to fix it. Having encountered the XP version recently and resolved the issue, I was able to easily remove the virus and associated rootkit. The difference this time was that unhide.exe failed to restore the start>all programs menu shortcuts, although it did manage to restore the folder structure. I read through and followed the instructions of another thread here: [URL]. Which did not resolve the issue. The output given by SystemLook is as follows:

As per a lot of other people on here, I'm having issues with connecting my desktop PC to my BigPond router. It will connect via wireless (have an installed D-Link DWA525 wireless card) but will not connect via LAN.I've changed the IP, DNS and Default gateways to the same as the other working PC's in the house, but still no luck. The mobo uses Realtek GBE Family PCI-E controllers, but for some reason it won't move off 10Mbps (even when I try to tell it to change this).I have tried new drivers, and have tried uninstalling drivers and letting windows install its own. None have worked. I've disabled V6, didn't work.My IPCONFIG ALL shows up the following: [code]

I have done things such as remove Bonjour, Stop services from Apple and Adobe, manually set my I.P. address, ping 127.0.0.1 with success, updated drivers, removed Microsoft office. Just trust me a HUGE list of things and none of them have worked. This all started when I had to restart my PC. My PC starts says the network is Unidentified, the repair tries to restart it, then suggest I restart my router, then says "Local area network is a invalid IP configuration."
We currently have 2 laptops (One with Vista the other with 7) and a desktop(XP) running on the network fine (Mine usually being the second desktop):
Windows 7 x32
4GB RAM
500GB HD
AMD Phenom II Black Edition 3.1Ghz
Nvidia 9800GT

I've had this problem since I bought a new desktop PC with windows 7 installed. Every once in a while my internet stops working (router+modem) and a yellow exclamation mark appears. When I use the windows solution utility I get two different messages:
a)either my wireless network connection does not have a valid IP
b) the default gateway is not available
I am using d-link dwa-127 wireless adapter since my computer does not have an integrated wifi card, and I have already removed norton, which could possibly be blocking my conncection. I have tried setting my IP manually, but it does not work.
At the beginning it all functioned normally, and even now it works, but it did not before. I also noticed that when it does not work it says 'Unidentified network', and when it does it says 'Smuc' (the ssid of our network). The internet as such is working this whole time, I always check it on my laptop with windows XP and an integrated WiFi card.

When i installed the windows, i had no errors, nothing whatsoever. But when i tried to go on the Internet 1st it gave me error that i am in Unidentified network, and i could see my step brothers PC on the network, and could go in that drive, copy/paste etc.. but i couldn't access Internet. I am constantly getting error with "Wrong IP Configuration."
I got no idea why i am getting this. in IPv4 properties i chose "Assign IPs by default" (or sth like that)
my network submask is 255.255.255.0,
and it assigns me submask of 255.255.0.0 , and i dont know why
Not sure about /flush or /renew in cmd, but i will try that today too..

I have been using Windows 7 beta (386) with no problems up until a few days ago.I've run into the The Network Adaptor "Local Area Connection" does not have a valid IP Configuration message. When I go to Network Sharing I see that I am connected to an Unidentified Network but unable to connect to the internet. This has happened all of a sudden.

The computer which has the problem is an Acer Aspire X3400, 64-bit operating system. I get the unidentified network no internet access thing come up when i click on the little symbol at the bottom which has the yellow warning triangle infront of it. I have tried disabling the connection and restoring it. Releasing the ip and renewing it. I have tried to update the driver (ethernet cable) but it says it is up to date. In the driver management there is a yellow triangle next to the USB network interface.

We set up three new terminals this week at the office; they're all running Win 7 Pro 32-bit. I set them all up simultaneously (literally sat at a desk and entered the same keystrokes at each of them), so I don't see any obvious reason that one is behaving differently from the other two. The essential problem is that the terminal doesn't see the Internet. Here are all the particulars that I think might be interesting, listed in no particular order:
- The terminal ran fine for several hours. Email access, Internet access, from 9 a.m. to 2 p.m. At that point, the user called me to show me a dialog box. I used System Restore to go back in time to 9 a.m. in case the user had somehow managed to do anything (though she's not an admin).
- IPv6 is disabled.
- The workplace uses Static IPs. The IP address is entered correctly in the IPv4 properties (x.x.x.213), but at cmd / ipconfig, I get this result: "Autoconfiguration IPv4 address: 169.254.95.187"
- In Network and Sharing Center, the network (which is only known as Unidentified Network) is set to type Public. When I reset it to type Work and reboot, it resets to type Public.

I was a bit of a loss and maybe it's because I have been out of the game for a long time but I came across a disturbing development. I call century link because my router was not connecting at the proper speed of 7 mbps. That problem was easily remedied over the phone but the lady said she could see several devices connected. This lost me a bit because I have a double router configuration. The Actiontech PK5000 i turned into nothing more that an internet modem. I disabled the DHCP and configured my Linksys E1200 for all the internal DHCP so there is only one cable going to the PK5000. I should technically speaking look like one user on there network with natural protection from the second router. I may be kidding myself or man I'm getting old but if someone can tell me how that works it would be fun to know and what would even be funner to know is how to stop it

Above is the error that comes up after I troubleshoot this issue. okay so to start off let me say the things I have done.
1. I have restarted my computer multiple times and restarted the modem and router.
2. I've checked my services to make sure that that weird code is not there and it was not.
This problem just came up recently and had no issues with it before and this computer has been running for over a year.

I am running Windows 7 x64 Ultimate on my desktop (home) and Windows 7 x64 Pro on my laptops. I bring my personal laptop to work which I use for emails and browsing. There is sensitive information that I would not like to share for obvious reasons. I am running into a problem making sure the information is not in "shared" mode while at work.
Work has their own network, which I am unable to connect to because the Sys Admin is lazy and will won't provide me a VPN connection directly to the system. So what I have done is use the public WiFi that we make available to our customers and connect through my own VPN off the public WiFi system. I want to make sure that I am not inadvertently sharing documents or other information doing so. When I connect to the network at work I use the "Public" setting.
What makes it more difficult is I have a similar situation at home, in which we have one internet connection through a router coming in and several people use the system. The location of the router is actually upstairs where I do not have access to, I use a Netgear WNR2000 v2 (I rent out rooms in my house), so I am forced to connect to the router wireless.
I personally am not a gamer, but one of the tenants is. I almost always use my VPN service at home to connect, but I am unsure if this is the correct set-up. I don't want to share my printers, video, etc. with everyone in the house. I am using Norton 360 for protection with Firewalls and Anti-virus software. I connect through Golden Frog VPN service for security.
I am going to connect my desktop Gigabit switch with my devices but again want my system secure, but not limited because of my situation. It is safe using the router for access and then creating this "sub-network" for my devices (for the router I am the admin)? Is there a better method or suggestion that one might have. I would really appreciate the input for this complicated matter. Should I change my workgroup for home and work? Currently its the default WORKGROUP domain for both.

I am running a small home network with 2 pc one on windows 7 and one on xp but the funny thing is that even if the second one is off this process starts by itself.I am running Windows 7 Professional x64, Windows media player 12?

I am on a windows 7 home premium, 64 bit Asus a53u. This is a friends computer. His USB, SD card, and webcam quit working 2 weeks ago and he came to me to fix it. He had a root kit in his registry, and a bunch of trojans.happili and generic trojans and another root kit. I can not get one of the viruses to uninstall (don't have sufficient permissions to get rid of it. Hiding in the ask toolbar updater) but it shouldn't be a problem because its been quarentined and is no longer running (sob was using 100% of the CPU). So I the drivers will not install. Period. I can download and install the realteak 2.0 but the drivers in the device manager will not install. I believe I got an error 0000027 (can't figure out where I got that from) Also I am not willing to spend any money on software. Hes not paying me and is not willing to reimburse either.

Need a little advice. Still dealing with the nasty infection. I have done a clean install where i wiped my hard drive for about 4 hours.
I am still dealing with the infection when i place a blank disk in the drive it will type into the start menu. I am a little unsure if it would be suitable to reinstall again and flash my bios or get hackthis logs done.
If i should flash my bios how do i do this?

my netgear wireless modem and wireless network were renamed and all the passwords reset. Hard reset to recover. I am still getting browsers redirected daily. All three browsers each will give message that setting have been changed when opened. IE will say search setting have been corrupted and mandate Bing. Internet Options will be reset to custom levels without a reboot. I have installed AVG 2012 paid. No scan from various scanners will show an infected file except some cookies. AVG rescue disk scan found 13 password protected files that were renamed. Broke AVG and required a reinstall. Password protected files were back by the end of the day. AVG says there should be NO password protected files in their sub-directories during a rescue scan. Their solution is a wipe and reinstall.What is the safest process of doing the HD wipe and reinstall? Just plugging the thumb drive in got me all this grief. Is reinstalling files from the DVD the same process? If i try to access my old files am i opening myself to reinfection?

After several days with a very patient and through BleepingComputer Volunteer, I believe my computer is malware-free. However, my computer itself still seems to be having issues. None of these issues occurred prior to the infection. My logs appear clean, but these issues remain:Mouse cursor "stutters" at times.Windows flickerStartup and shutdown take excessively long at times, others it is very fastShortcut icons (but not regular icons) have some sort of "blank" icon in front of them.Here is a link to the malware removal threadMalware Removal ThreadAttached as well is a picture of the icon situation.

So, I'm trying to get an online game working, thinking they had issues. Come to find out, neither my firewall nor updater has been working since January.Here's the link to my original thread, where Gringo helped me get rid of the infection:I dug around and found a registry file to get the firewall working, but I'm stumped on the Updater.
