I have WinXP Home SP3 with all updates, and ZA Extreme Security with all updates. My system abruptly slowed to an extreme crawl; it was taking five minutes+ for a browser to open. I ran an ultra-deep scan using ZA, then Malwarebytes, Spybot, and Spyware Blaster. No problems found. I tried to identify something that fails consistently so I would have some kind of symptom to report, and found the following, which obviously aren't solid failures or I wouldn't be posting this message.
It happened that if I started either IE8 or Firefox browser, the task manager showed they took 99% of processor, and the LAN icon in the system tray froze with the left (send) part of the icon on solid.
I've been helped at bleeping computer before, so I went ahead and looked at the initial directions for gathering information - running Defogger, dds.scr, and GMER. While running GMER, the system froze completely (the mouse pointer would not move, and I couldn't switch tasks) and displayed the following message:
"Windows - Delayed Write Failed
Windows was unable to save all the data for the file \Device\HarddiskVolume1\$Extend\$UsnJrnl:$J. The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere."
I pressed the Power button to force power off. After rebooting I tried again and got GMER to finish ok with an ark.txt file. I'm probably premature running these tools, but I don't know if the system will be stable enough to let me run them successfully again. If you want to look at their results, I have the files they created.
