Hello,

I wasn't sure if I should put this under malware or vista...

For a couple months my computer has been extremely slow to do anything 70% of the time, including simple things like open a folder, play an mp3, open control panel, etc. It has occasionally had periods (several days in a row) where it will run really loud for 5 seconds before shutting down and restarting on its own. When it does this it does it consistently every 45 minutes. Then it will go a week or so without doing that all on its own. (I have been good about keeping the vents clean and blowing out the interior).

But last week, sister in law came in from Miss., and used facebook a great deal(that's the only change we can think of), which we've never used, and the computer went nuts. Now it freezes anywhere from 30 seconds to 10 minutes after starting in normal mode. The power button has to be held down to shut it off and then pushed again to start again. It starts and runs fine in safe mode with networking, no problems. But starting up in normal mode now, it consistently has a problem starting either 4 or 5 times in a row, each progressively worse, with windows wanting to do a startup repair on the last one, before finally starting successfully in normal mode, only to freeze shortly thereafter. It will freeze whether we're doing anything or not.

I have Trendmicro antivirus and their help site told me to run Hijackthis which I did and then it suggested posting that log in one of these forums. I've read several posts in several different forums, and don't want to do anything else until you tell me where to start. My suspicions are malware, a posible upgrade from TM, something Vista related, something having to do with addons, or something processor or memory related. But really I don't have a clue.

My computer is a Gateway GM5478 with Vista Home Premium, straight off the shelf from Best Buy 2 years ago. No hardware modifications or upgrades except the additon of one more dvd drive which best buy did before I brought it home the first time.

Intel Core2 Quad processor Q6600, each core 2.4 ghz, 2x4mb L2 cache, 1066 mhz fsb.

Nvidea GEforce 8500gt with 256 mb.

500gb SATA II.

Dual channel 2048mb DDR2.

Vista service pack 2.

32 bit op system.

Under device mgr, the only yellow ! is under system devices, "consumer IR devices".

Any help someone can give would be VERY VERY appreciated! :) Thank you, Joe

mse antivirus (uninstall present one) http://www.microsoft.com/security_essentials/
superantispyware http://majorgeeks.com/SUPERAntiSpyware_d5116.html
malwarebytes http://majorgeeks.com/download.php?det=5756

I used ccleaner, SAS, and malwarebytes. They found a few things, but didn't fix the problem. The computer did run about 20 minutes before freezing up, which is a little longer than it had been doing lately, but not close to a fix. Any ideas? Thank you again.

Since my computer is running fine in safe mode with networking, is there a way to troubleshoot other programs while in safe mode? I want to rule out my trendmicro antivirus software.

With the information you have provided I believe you will need help from the malware removal team. I would like you to start a new thread and post a DDS log HERE and include a link to this thread. Please make sure that you read the information about getting started before you start your thread.

It would be helpful if you post a note here once you have completed the steps in the guide and have started your topic in malware removal. Good luck and be patient. Help is on the way!

Reference: http://www.bleepingcomputer.com/forums/topic370568.html/page__p__2075923#entry2075923

Now that your malware log is properly posted, 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 Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the logs 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 Malware Removal 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 Malware Removal Team members are very 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 Malware Removal 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 Malware Removal Team member is already assisting you and not open the thread to respond.

To avoid confusion, I am closing this topic.

Louis
