I need some assistance. I have ran a couple of different programs on my computer and they have come up with zero for viruses, trojans, spyware, etc. BUT, my computer still boggs down, reboots itself after a mere 5 - 10 minutes!

So, I'm curious IF it's NOT a virus. What would cause my computer to just "reboot" by itself. And sometimes I get a message on the screen, a little box that says something like "WinNT system is shutting down now, you have 1 minute to save, etc" I am running WinXP Home.

Please Help!

Thanks!

:thumbsup: to BC mmof3bys,

That's a classic symptom of infection by the Blaster worm. We need you to tell us details about your computer including CPU type, RAM capacity, hard drive size, what version of windows, what anti-virus or anti-spyware you have and some details about your applications.

If the infection is serious you may need to seek expert help in the HJT forum. If that is necessary then please read the 'Preparation Guide' before posting to:
http://www.bleepingcomputer.com/forums/Hij...alysis-f22.html

For now you can stop the system from rebooting by clicking Start>run and typing shutdown -a. That should give you time to download and run the programs I'll list below:

Download the Trend Micro system cleaner from here:
Trend Micro System Cleaner
Printout the readme.txt file for specific instructions on how to run this utility.
Physically disconnect from the internet when told to shutdown anti-virus software.

Download McAfee AVERT Stinger utility and see instructions for use, from here:
Stinger

Is your Anti-virus program current and updated? If not you can download a free anti-virus program here (US Link): AVG Free
When you have downloaded and installed it you need to go online to register it and update it. (It will probably prompt you to do this.)
Once you have installed AVG uninstall your old Anti-Virus software because you should only have one running on your system.

Do you have any anti-spyware installed? If not download and update all of the following:Reboot your computer in Safe Mode and run Stinger, the anti-virus scan and anti-spyware scans there.
If you are not sure how to boot in Safe Mode there is a tutorial here: Safe Mode


Make a note of what you download as you should inform the HJT team if you end up going there.

Let us know what happens. :flowers:

It is also possible that the cpu is overheating.

I ran "Stinger" and it came up with the following:
C://windows/sys32/i
Found the W32/sdbot.worm! ftp virus!!!
And it deleted it! (GREAT!)

I ran it also in Safe Mode and it found nothing.

For some reason I could not get the Trend Micro System Cleaner to work/run.

Although my computer seems a little better since it is now rid of that "worm" it is still re-booting on it's own!

I'll try a few more suggestions and see what happens, thanks everyone for your input!
I appreciate all I can get.. keep them coming!

Did you follow the readme instructions carefully? You need to download a Trend Micro pattern file for System Cleaner to use - did you do that?

Did you download and run ALL the anti-spyware programs I suggested?

Once you have done that try some online anti-virus scans and anti-trojan scans:

Online trojan scanner: http://www.windowsecurity.com/trojanscan/

Here are some links to free online Anti-Virus scans. They do take some time to load and run and in some cases you can only use Internet Explorer, with ActiveX enabled, to access them but they are an excellent support for your existing anti-virus program. Choose a couple of these:

Panda Active Scan online - http://www.pandasoftware.com/activescan/
Internet Explorer only. Requires email address. Requires Active-X components to be installed. Approx 12MB download.

BitDefender online scan - http://www.bitdefender.com/scan/licence.php
Internet Explorer only. Must agree to a EULA. Need to allow installation of an Active X component.Some of the options are not clearly explained.

McAfee online scan - http://www.pcpitstop.com/freescan/

Security Advisor (?) - http://www3.ca.com/securityadvisor/virusinfo/scan.aspx

Trend Micro Housecall - http://uk.trendmicro-europe.com/enterprise...call_launch.php
(European version, supports Netscape, Mozilla, Firefox and Opera)
or http://housecall.antivirus.com/ (IE only)

Kaspersky - http://www.kaspersky.com/scanforvirus
Link to 'Online Scan' at the top rhs of the page. Requires IE and Active-X components.
"does not scan RAM, boot sectors and MBRs, so it cannot detect malicious code located in these areas."
