I believe a got virus. My computer began giving me the bluescreen constantly, so I managed to quarantine many viruses. The bluescreen problem continued to occur, but not as frequently. Now, just after turning on the computer, I get the black screen with a cursor I cannot move. If I push ctrl+alt+del, the computer restarts. I haven't made any progress on the black screen. I have a Toshiba laptop with Windows Vista. Please help!!!

I would fix the virus problem first before attempting to log into yahoo messenger. If you have a virus you need to quarantine it. If you have a anti-virus make sure it's up to date. Run the a scan on your pc and do a window's update. The anti-virus should be able to quarantine the virus or give you an option to do so.

search the quarantine folder, and you will find your file, usually the quarantine folder is hidden, this mean you must check the hidden folder search

Symantec/Norton AntiVirus (SAV for Windows, NAV for Mac OS X) is a virus protection program distributed by the Symantec Corporation, offering effective protection features, including infected file quarantine, online virus protection updates, and an automatic scheduler. SAV/NAV is designed to start running as soon as your computer's operating system starts. It runs in the background, checking all vulnerable files for possible infection by malevolent programs called viruses and worms. SAV/NAV does this by looking for the identifying signatures of these worms and viruses and comparing them to known viruses for which it has files. When it detects an infected file, it notifies you and manages the infection according to your preferences.

it may be due to virus is running. You can kill the process from task manager or tuneup task manager. After killing the process you will able to quarantine the virus file. Best of luck .

I have a westell 6100 modem also- The light your are talking about always blinks- it blinks as long as the internet is working (it is sending and transmitting data)

Blinking light means that firmware on your DSL modem just got updated. The modem is pinging the Networ/Computer connected to it. If you open your Modem Page 192.168.1.1 you will see the difference, unless you never have done it before.

How about go to windows Task manager and go to processes. Look for Kragg.exe. Dellete it. It is a virus that go infected the boot sector. Go first to F8 or safe mode. Then control alt dellete so you can go to task manager. If you are not sure of this kragg.exe virus, you may scan your computer with your antivirus while in safe mode. Maybe your antivirus will quarantine the kragg.exe virus.
