Computer reboots every so often

[davidjoyce]

Hi,

I've a problem with my computer whereby it keeps rebooting every so often. A dialog appears saying that the system is shutting down and you have 60 seconds to save your work. I've attached the screenshot. So far my Norton anti-virus software, and my spyware software haven't found anything. I've also downloaded some checker for Microsoft but that too didn't find anything malicious. I'm aware of a msblaster virus that had similar behaviour, and I've followed the removal steps for that, but the computer still reboots.
So can anyone help me with this please as I am at an absolute loss on what to do? Thanks.

Also, I've attached the HijackThis output if this is of any use.

Welcome to Majorgeeks!

Note you said Norton Antivirus but all I see is McAfee!

Most people are under the very mistaken misconception that HijackThis is a scanning and detection tool. It is not! HijackThis is simply a tool that is used to identify browser hijackers and in some cases it will show entries for some malware that is for instance running at startup. A HijackThis log shows the following:

• a running process list with no reference to good or bad
• it lists the contents of a selected group of registry keys that is an an extremely small subset of the tens of thousands of keys that may exist. Again no reference to good or bad.
• and some of the above keys that are shown may show some non-Microsoft system services that are running. Again with no reference to good or bad.

The decision on what is good or bad is left a person with significant Windows and malware cleaning experience.

HijackThis does not come close to showing all malware that could be hiding on a PC. Anyone who has an infected computer and is relying on HijackThis without the benefit of running other scans such as Spybot, Windows Defender, BitDefender & Panda, CCleaner, etc. are more than likely still infected. In most cases, where there is one virus/trojan there are more.

The goal of this forum is to remove all malware, and this cannot be done properly by just seeing a HijackThis log especially when it is not even installed and run properly.


Please follow our standard cleaning procedures which are necessary for us to provide you support. Also there are steps included for installing, renaming, running, and posting HijackThis logs as attachments.

• Run ALL the steps in this Sticky thread READ & RUN ME FIRST Before Asking for Support
• Make sure you check version numbers and get all updates.
• Very Important: Make sure you tell us the results from running the tutorial...was anything found? Were you unable to complete any of the scans?...Were you unable to download any of the tools?...Did you do the on-line scans as suggested? etc.

• After doing ALL of the above you still have a problem make sure you have booted to normal mode and run the steps in the below link to properly use HijackThis and attach a log:

Downloading, Installing, and Running HijackThis

Make sure you also rename HijackThis.exe as suggested in the procedures. Use analyse.exe for the new name. This is very important due to some new infections going around.

• When you return to make your next post, make sure you attach the following logs and that you have run these scans in the following order too:
  • CounterSpy - only for Windows XP, 2K, & NT users
  • AVG Antispyware log - ONLY IF NEEDED you were not able to run CounterSpy. - only for Windows XP, 2K, & NT users
  • Bitdefender - from step 6
  • Panda Scan - from step 6
  • runkeys.txt - the log from GetRunKey.bat
  • newfiles.txt - the log from ShowNew.bat
  • HijackThis

NOTE: You can only attach 3 files in a single message so it will require that you use two messages to attach all of these logs!
