Welcome to BC hiroshi
See BC's list of
Freeware Replacements For Common Commercial Apps. There are several free
online anti-virus scans listed which you can perform. I would also recommend that you download and scan with
SUPERAntiSpyware Free in "
Safe Mode".
Please update the defintions before performing a scan. If you encounter any problems while downloading the updates, manually download them from here and unzip into the program's folder.In Windows XP, the
default setting is for the computer to reboot automatically when a fatal error occurs. You should be able to see the error by looking in the
Event Log. Read "
How To Use the Event Viewer Applet".
An alternative is to turn off the automatic reboot feature so you can actually see the error code/STOP Message when it happens -
this is also known as the Blue Screen Of Death (BSOD).To change the recovery settings and
Disable Automatic Rebooting, go to Start > Run and type:
sysdm.cplClick Ok or just press
WINKEY + Pause/Break keys to bring up System Properties.
- Go to the Advanced tab and under "Startup and Recovery", click on the "Settings" button and go to "System failure".
- Make sure "Write an event to the system log" is checked and that "Automatically restart" is UNchecked.
- Click "OK" and reboot for the changes to take effect.
Doing this won't cure your problem but instead of crashing and restarting you will get a blue diagnostic screen with an
error code and other information that will allow you to better trace your problem. You can use Google to search the error code or use the links below to investigate and troubleshoot.

Safe Mode" is a troubleshooting mode designed to start Windows with
minimal drivers and
running processes to diagnose problems with your computer. This means some of the programs that normally run when Windows starts will not run.
The Windows operating system
protects files when they are being accessed by an application or a program. Malware writers create programs that can insert itself and hide in these protected areas when the files are being used. Using "Safe Mode" reduces the number of modules requesting files to only the essentials to make your computer functional. This in turn
reduces the number of hiding places for malware, making it easier to find and delete the offending files when performing scans with anti-virus and anti-malware tools. In most cases, performing your scans in "Safe Mode" speeds up the scanning process.
"
Safe Mode With Networking" gives you the additional capability to access your LAN if you are on a network and that includes Internet access. This is useful since you can run on-line anti-malware and anti-virus scans, download drivers, etc. if you need to.
