Help,

I have been unable to access the internet through any browser (IE, Firefox, safari) and my anti-virus (trend micro) can not update.

I was using the internet yesterday and my laptop (dell that is using XP) closed because the battery ran out of juice. When I plugged it in again and restarted, I could not get a "connection". I get signals and they appear to be fine.

I restored to different points multiple times.

I was able to "connect" twice. Only breifly after a restore and after installing a MS security update, but than nothing.

I was also able to "connect" once using a ether net cord, but then after less than a minute, blocked.

TrendMicro is logging the blocking of access messages something to do with webcam and ie explorer changes. I never saw these before and don't have access or remember exactly at the moment.

I am able to access the internet now through an ethernet cord in safe mode.

I do not know what to do. I feel like it could be a progressive issue, because before entering safe mode this time. I was unable to open any programs through the start menu because I would get a message saying that not enough memory please close down programs even if I did not have any open.

Any help appreciated.

Thanks!

Before we start fixing anything you should print out these instructions or copy them to a NotePad file so they will be accessible. Some steps will require you to disconnect from the Internet or use Safe Mode and you will not have access to this page.

Please download DrWeb-CureIt and save it to your desktop. DO NOT perform a scan yet.

Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with Dr.Web CureIt as follows:
  • Double-click on drweb-cureit.exe to open the program and click Start. (There is no need to update if you just downloaded the most current version
  • Read the Virus check by DrWeb scanner prompt and click Ok where asked to Start scan now? Allow the setup.exe to load if asked by any of your security programs.
  • The Express scan will automatically begin.
    (This is a short scan of files currently running in memory, boot sectors, and targeted folders).
  • If prompted to dowload the Full version Free Trial, ignore and click the X to close the window.
  • If an infected object is found, you will be prompted to move anything that cannot be cured. Click Yes to All.
  • When complete, click Select All, then choose Cure > Move incurable.
    (This will move any detected files to the C:\Documents and Settings\userprofile\DoctorWeb\Quarantine folder if they can't be cured)
  • Now put a check next to Complete scan to scan all local disks and removable media.
  • In the top menu, click Settings > Change settings, and UNcheck "Heuristic analysis" under the "Scanning" tab, then click Ok.
  • Back at the main window, click the green arrow "Start Scanning" button on the right under the Dr.Web logo.
  • When the scan is complete, a message will be displayed at the bottom indicating if any viruses were found.
  • Click "Yes to all" if asked to cure or move the file(s) and select "Move incurable".
  • In the top menu, click file and choose save report list.
  • Save the DrWeb.csv report to your desktop.
  • Exit Dr.Web Cureit when done.
  • Important! Reboot your computer because it could be possible that files in use will be moved/deleted during reboot.
  • After reboot, post the contents of the log from Dr.Web in your next reply. (You can use Notepad to open the DrWeb.cvs report)

Log on as an administrator, go Start > Run and type: "cmd". In the window that appears type: "netsh winsock reset". When the program is finished, you will receive the message: "Successfully reset the Winsock Catalog. You must restart the machine in order to complete the reset." Close the command box and reboot your computer.

Go Start > Run > type: "cmd" In the window that appears type: "ipconfig /flushdns". Close the command box.

Go Start > Control Panel > Network Connections. Right click on your default connection, usually Local Area Connection or Dial-up Connection if you are using Dial-up, and and choose Properties. Double-click on the Internet Protocol (TCP/IP) item. Select the radio button that says "Obtain DNS servers automatically". Reboot.

Warning: Some Internet Service Providers need specific DNS settings. You need to make sure that you know if such DNS settings are required before you make this change.
