Hi.

I play World of Warcraft and my account got hacked. That got resolved, however since then at random intervals my PC either freezes and I have to press the restart button on the base unit, or it just switches off completely. When it switches off, there is no warning. It's literally as if it's been switched off at the power socket.

No error messages come up prior the the freezes and power offs.

I use Windows XP with SP3. The fans are fine and the CPU is nice and relatively cool. I've run Norton Internet Security 2010 in regular and Safe Mode and so far it only found a few suspicious cookies which have now been removed.

The only other thing I've noticed (not sure if this helps) is that if I right click on a picture to save and I hit the save button, the window with IE open comes to a stop for a while as if it's having a think about it. This has never happened before.

Thanks in advance for any help you can give.

Crashes (BSOD), unexpected shutdowns, sudden freezing, random restarting, and booting problems during or after running anti-malware scanners can be symptomatic of a variety of things to include problems encountered with certain types of files (.exe, .dll, .sys, .cab, archived, compressed, packed, etc) that are being scanned. Crashes can also be symptomatic of hardware/software issues, overheating caused by a failed processor fan, bad memory (RAM), failing or underpowered power supply, CPU overheating, motherboard, video card, faulty or unsigned device drivers, CMOS battery going bad, BIOS and firmware problems, dirty hardware components, programs hanging or unresponsive in the background, and even malware. Even legitimate programs like CD Emulators (Daemon Tools, Alchohol 120%, Astroburn, AnyDVD) can trigger crashes, various stop error messages and system hangs so you may or may not be dealing with multiple issues which are not all malware related. Troubleshooting for these kinds of issues can be arduous and time consuming. There are no shortcuts.

When Windows XP detects a problem from which it cannot recover, it displays Stop Error Messages which contain specific information that can help diagnose and resolve the problem detected by the Windows kernel. An error message can be related to a broad number of problems such as driver conflicts, hardware issues, read/write errors, and software malfunctions and malware. In Windows XP, the default setting is for the computer to reboot automatically when a fatal error or crash occurs. You may not see the error code because the computer reboots too fast.

An easier 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 the Automatic Restart on System Failure in Windows XP, go to Start > Run and type: sysdm.cpl
Click Ok to open System Properties.

Alternatively you can 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 manually for the changes to take effect.
This can also be done in the Windows Advanced Options Menu as shown here here by pressing the F8 key repeatedly like you would do for entering safe mode.

-- Vista users can refer to these instructions: How To Disable the Automatic Restart on System Failure in Windows Vista.

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 to include file(s) that may be involved which will allow you to better trace your problem. Write down the full error code and the names of any files/drivers listed, then provide that information in your next reply so we can assist you with investigating the cause. Without that specific information, we would only be guessing rather than troubleshooting.

I've purchased a new PC. Windows 7 based. I've installed most of the programs I normally use and this one is now shutting itself off automatically! I've followed the instruction on how to switch off the auto-restart so I can get a BSOD report for you, hoever no BSOD appears. The screen freezes, then the PC restarts.

I've had the wiring in the house checked out, it's fine. I've removed all peripherals bar the mouse and keyboard, and it's still rebooting at random intervals, no matter with I'm watching a movie, listening to music, playing WoW or just browsing the net.

Is there anything else I can do to get info for you?

Hello,

Now that you have posted a log here: http://www.bleepingcomputer.com/forums/t/326041/possible-malware-infection/ you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a MRT Team member, nor should you ask for help elsewhere. Doing so can result in system changes which may not show in the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the MRT Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the MRT Team members are EXTREMELY busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the MRT Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRT Team member is already assisting you and not open the thread to respond.

Please be patient. It may take several days to get a response but your log will be reviewed and answered as soon as possible. I advise checking your topic once a day for responses as the e-mail notification system is unreliable.

To avoid confusion, I am closing this topic. Good luck with your log.

Orange Blossom :thumbsup:
