Hi all, hope you can help.

I've got a major trojan that ended up on my computer. When I start up my computer, there are errors related to a specific kernal error 1257 (or 1259, not sure which, I'll check again later) so there's a registry problem. Everytime I open a folder, the comp slows down. Sometimes I cannot open "My Computer" at all. I cannot copy or paste anything without the computer slowing down to a stop. Task Manager doesn't show anything unusual, or anything taking up CPU speed. I am eventually forced to restart the computer, and again the same thing happens. A .sys file was missing on the computer, not sure which, but it came up when I was trying to reinstall/repair Windows, which I eventually did, albeit with errors during the repair phase involving missing files need for reinstall. Registry repair tools have fixed the registry, then after reboot everything is screwy again. McAfee isn't detecting any viruses at all, and TrendMicro's online house call thing doesn't run long enough to scan well since the comp slows down too far for it to finish.

I can't back anything up. I can't System Restore. Repairing Windows did nothing. The computer is painfully slow and not working well.

So... what can I do? What is the problem specifically? What are our options? Can the data be saved if we take it to a techie?

Thank, please help... we have so much important info on our computer that we'd hate to lose it.

Some types of malware can result in a system so badly damaged that a Repair Install will NOT help!. Reinstalling Windows without first wiping the entire hard drive with a repartition and/or format will not remove the infection. The reinstall will only overwrite the Windows files. Any malware on the system will still be there afterwards. Starting over, reformatting the drive and performing a clean install of the OS removes everything and is the safest action. Please read "When should I re-format?" and "Reformatting the computer or troubleshooting; which is best?".

Should you decide not to follow that advice, I can give you instructions on how to post a HijackThis log so your system can be checked for malware.

If you choose to reformat and perform a clean install, but need to salvage you data, another option is to remove your hard drive and install a new one. Then you could make the old one a "slave" drive. That way you should be able to access it and salvage some of your data files.

Thank you for the reply. The problem is that I cannot even transfer any data within the computer, how will I be able to do it after I install a new one?

Also, if I partition the drive, will the new, clean partition be able to grab the data from the infected partition?
