I have a Dell, Windows XP service pack 3

After i log in my computer freezes
At first when the problem started these blank black windows poped up with just a ( _ ) blinking and the name of the window was like symant.exe I think. There were like 7-9 of them and I just closed them. But now after i log in, all the normal things load up like my registry cleaner and other programs at start up but the whole screen freezes, I can move my mouse though and use ctrl alt del to run firefox but thats it. I can't access my desktop icons or the start button. I have to use safe mode to do that. Sometimes my computer will also runs at CPU usage 100.

Can internet explorer be the problem? I don't even use it but I can't seem to get rid of it when i try.

Any more info that I can provide?

I don't trust registry cleaners as they often cause more harm than good.

Try running this scan, you can copy if over from another computer on a CD or pen drive if you need to.

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)

The power of accurate observation is commonly called cynicism by those who haven't got it.

—George Bernard Shaw
