Why is my PC Randomly Shutting Down + Booting up!?

Question

Note: I have ALOT of viruses. Because before I never had any antivirus software (not I do)

There's this virus that my antivirus program says requires rebooting in order to get rid of it. But even when I reboot it, it's still there.

I think the virus that won't go away is called hwclock.exe or something like that...

Answer 1

this is not a virus, this is a trojan, or spyware. Immediately get free SpyBot and Ad-Aware from download.com. Download, install and run Ad-Aware first, then SpyBot. Remove anything either one of them finds. Keep the updated after this, and run them often, daily if you are on the internet a lot.

You don't have to reformat your hard drive, but do a disk cleanup after running the adware and spyware. Click on Start, Programs, Accessories, System Tools and Disk Cleanup. Remove everything it finds. After that you should be in good shape.

Answer 2

Do these step and use your AV program when called on to scan with it. Make sure your AV program is updated.

TEMPORARILY SHOW HIDDEN FILES AND FOLDERS.

1. Click Start, and then click Control Panel.

2. Click Appearance and Themes, and then click Folder Options.

3. On the View tab, under Hidden files and folders, click "Show hidden files and folders", and clear(uncheck) the "Hide protected operating system files" check box.

IMPORTANT: Files are hidden by Windows for a very good reason. It is not wise to experiment with these files. Unfortunately, to successfully remove modern spyware we must turn this protection off temporarily. Please turn the protection back on when you have finished cleaning your system.


EMPTY INTERNET EXPLORER BROWSER CACHE:

1. On the Internet Explorer Tools menu, click Internet Options.

2. On the General tab, in the Temporary Internet Files section, click the Delete Files button. Select the Delete all offline content check box in the confirmation dialogue box that appears, click OK. Click OK again.

RESTART IN SAFE MODE:

To do this you need to hold down or repeatedly tap the F8 key while the computer is booting (when the computer is displaying a black screen with white text). When the boot menu appears, use your keyboard arrows to select "Safe Mode."

Safe Mode can look quite ugly. The color may look bad, and all of your desktop icons will be very large. This is normal.



START THE SCAN WITH YOUR ANTI-VIRUS OR ANTI-SPYWARE PROGRAM.


When the scan and removal are completed REBOOT COMPUTER. This will restart you in normal mode. DON'T FORGET TO RESET HIDDEN FILES AND FOLDERS.


NEW RESTORE POINT.

The RESTORE POINTS may be infected with the Malware and cannot be used.

HERE'S HOW:

1. Click Start, and then click Control Panel.

2. Click Performance and Maintenance, click System, and then click on the System Restore tab.

3. Select the Turn Off System Restore check box, click Apply, then restart your computer.

4. Return to the System Restore Tab and turn System Restore back on.


TO SET A NEW RESTORE POINT:

1. Click the Start button.

2. Point to Programs, then navigate to Accessories, then System Tools, then click System Restore.

3. Choose Create a restore point, and then click Next.

4. In the Restore point description box, type a name for your restore point, and then click Next.

5. Click OK.

NOTE: If you are using Windows XP Service Pack 2 (SP2) and are unable to access the Internet after removing Malware, there is a command that may fix the problem. It works by resetting the winsock catalogue. Click on Start, then Run and type CMD in the box. Click OK. Type "netsh winsock reset" (no quotes)into the DOS window that appears.

I suggest that you try to carryout system restore to a day previous to the day when there was no virus or any problems. It may be a few weeks or months back. You have to decide the date. Detailed instructions are posted at http://fixit.in/systemrestore.html
The problem is likely to be solved. Then,You insatll a standard antivirus soft ware such as Norton, AVG , Avast ( free antivirus software and Ad-aware, Ewido ( free spyware removers). You can download free softwares at

Update and run your Anti-Virus program. Don't have one? You can run a free online scan from Trendmicro. When I have tested it it takes some time to run it but it may be time well spent if it can fix any problems.

Download, update and run Spybot---http://www.safer-networking.org/ . Don't forget to use the Immunize feature.

Download, update and run Adaware---http://www.lavasoftusa.com/software/adaware/products/select_your_product.php
