Guest Rama Posted April 16, 2009 Posted April 16, 2009 Windows XP Professional; HP-Compaq Computer. Downloaded the Malicious Removal Tool from Microsoft website after my computer started shutting down suddenly when it is scanned either by anti-virus or Ad-Aware software. However, instead of removing the virus or whatever, this tool too is shutting down the computer like Ad-Aware or Anti-virus software. By shutting down, I mean, the computer is suddenly switched-off (not normal shutting down) and my monitor goes to sleep. If I try to start the computer within 30 minutes, it will close half way through booting. This confirms, I think, that my computer harbors a virus. Can someone tell me how to get rid of this virus please? Thanks in advance. Quote

Guest Richard Urban Posted April 16, 2009 Posted April 16, 2009 What you explain is a case of over heating. When you scan you place the CPU and hard drive under extreme load which you normally do not have. The computer overheats and shuts down. Waiting half an hour allows it to cool sufficiently to restart. I have never heard of a viral or malware infection that shuts you down for 1/2 hour and then allows normal computer operation. -- Richard Urban Microsoft MVP Windows Desktop Experience "Rama" <Rama@discussions.microsoft.com> wrote in message news:8B823791-0ED3-4CDC-A5B6-7AA7CEE1DFF9@microsoft.com...<span style="color:blue"> > Windows XP Professional; HP-Compaq Computer. > > Downloaded the Malicious Removal Tool from Microsoft website after my > computer started shutting down suddenly when it is scanned either by > anti-virus or Ad-Aware software.

Guest Peter Foldes Posted April 16, 2009 Posted April 16, 2009 Rama I have to agree with Richard Urban on this one. You are overheating and I would check for blockage of the fans in the Power Supply and CPU (dust bunnies) or your computer is backed into a bad spot where it does not get ventilation or the fan exhaust is blocked by a wall or by dust or defective. -- Peter Please Reply to Newsgroup for the benefit of others Requests for assistance by email can not and will not be acknowledged.

Guest Rama Posted April 17, 2009 Posted April 17, 2009 Hi Richard, You give me hope! But as you say, if the computer is overheating, why does it not shut down when I continue to work for any long time. It prematurely shuts down only when I try to scan the computer with anti-virus, ad aware or windows malicious software removal tool. Computer should not be overheated (and in fact, not over heated) when I start the computer after 4 hours stoppage? Still when I tried to scan after renaming 'mrt' as 'rama.' More over, I tried to start the computer in 'safe mode' with networking, but it doesn't boot at all, never. I'm not able to boot the computer in safe mode. There must be some intelligent being, style_emoticons/, or script preventing such operations, I think. But I'm open to your suggestions. Thanks.

Guest Rama Posted April 17, 2009 Posted April 17, 2009 Hi Peter, The computer is placed under the table with sufficient ventilation, I think, and the room is air-conditioned. The temperature is a constant 25 C. Another development I forgot to mention is that the Ad-Aware program is not opening at all now and when I want to shut down, I get the message that Ad-Aware program is not responding and whether to end it 'now' or to 'wait.' All these seem to point towards a virus infection. But then I don't surf the Net. I visit about 10 to 15 websites on the whole. That is all my activity. These are all accounting firms from whom I download data and after working upload back to them. As you know, this is our peak tax season. Thanks for taking time to respond. I promise to try to scan again after resting the computer a few hours, and it is completely cooled down.

Guest Rama Posted April 17, 2009 Posted April 17, 2009 Hi, You've surmised correctly about the security status of the computer. No, I don't feel ashamed to say I don't know anything about computers. But time is a very crucial factor at this time of the year for us accountants. So, I'm thinking, why not I install Windows Vista as a second operating system and move my files / data to Vista and continue to work? I had serious problems with Windows XP SP3. It is not compatible with my accounting and tax preparation software. These programs go on crashing after few minutes of working, but that problem is not there with Vista OS. Do you think it will work? Thanks. "PA Bear [MS MVP]" wrote: <span style="color:blue"> > Is the machine fully patched at Windows Update? (I suspect it isn't.) > > 1.

Temperature (a power supply that was defective long before these problems started), a defective component that is slowly failing at a lower temperature each month, a mismounted heatsink, etc. I too can wildly speculate and double that number of suspect. And still you have no answers. What does the system (event) logs report? If a computer is from a more responsible manufacturer, execute its comprehensive hardware diagnostics. Diagnostics run without any OS - a perfect example of breaking the problem in half and viewing only one half a problem. A perfect example of eliminating complications from the other half. Do not fix anything based on wild speculation. For example, installing Vista on defective hardware would only result in defective hardware and a defective OS. If you think you are confused now, wait until you do that mistake. Doors are sticking all over the house. So do you fix all doors OR first see what is wrong - the crumbling foundation. The power supply 'system' (which is more than just a supply) is a computer's foundation. It can make everything else act defective. And you know nothing about that 'system' until measuring its numbers with a 3.5 digit multimeter. One minute to measure any one of purple, orange, red, and yellow wires from power supply where wires enter the nylon connector on motherboard. Those numbers will also report facts that will only be apparent to those with hardware knowledge. Numbers are best taken when computer is under maximum load. Maximum load means playing a complex video (ie a movie), while downloading from the internet, while playing sound loudly, while searching the hard drive, while playing a CD-Rom, while powering devices on USB ports, etc. Now those numbers define the power 'system' as good or bad definitively - without doubt. Once you have a definitive answer, then move on. Others have discussed temperature. But your computer must work just fine in a 100 degree F room. If temperature sensitive in a 70 degree room, then your problems are major. For example, does you BIOS measure CPU temperature? Comprehensive hardware diagnostics would report that number. Or (more likely) a component has been defective for so long that it once never worked at 100 degrees F and now does not work even at 70 degrees. Heat (ie hair dryer) is a diagnostic tool to find defective hardware. So many other solutions are available. Little tests that take minutes and answer without doubts. But first do above three. And again, do not try to fix anything until the problem is first identified. Quote

Guest Rama Posted April 18, 2009 Posted April 18, 2009 Hi westom, Very well said and most practical advice. I can follow some parts but my knowledge of computers is only skin deep. Thanks for taking time to show the right path to solve computer problems. Well, the good news is it looks like it is HEATING that shut down the computer. Because, I let the computer rest for 5 hours, then started it and put it in anti-virus scan. It has successfully completed the scan and there is no virus. Computer is clean. Now I've to see why the Ad-Aware is not opening. Thanks to you PA Bear, Richard and Peter for your guidance.

Months later, at 90 degrees. Eventually failing at 70 degrees. Using only observation, one might blame heat rather than use heat as a diagnostic to find the problem. Machine boots. Hairdryer on highest heat setting causes a system crash only when that selected IC is heated. Heat gets blamed for a hardware problem that even existed before the warranty expired - which is why burn-in testing executes comprehensive diagnostics even when room temperature is above 100 degrees F. Hairdryer is a diagnostic tool to find defective hardware. Yes, maybe it is heat. Same symptoms may be observed when power supply voltages are too low. It would take 30 minutes for failing electrolytics to cool sufficiently to properly filter. Nothing from that test was useful other than to confirm what others have been saying all along. Malware would not (typically) explain your failures. Insufficient facts conclude failure due to temperature. Quote
