Hi All!

I have a Sony laptop, VGN-FS760W, running Windows XP Home, SP3 (Sony OEM). I've upgraded the RAM to 2GB, and recently upgraded the hard drive to 250MB.

The problem is that the computer has become very slow when doing any Internet activity. Ursing either IE 6.0.290 or Firefox 3.0.6, will hang after about 8-12 minutes of activity. Once it hangs, it will usually recover if I wait another 8 minutes or so.

While the browser is hung, I can still ping sites by URL, and they do respond quickly.

The problem seems to be worse with a wireless connection, but also does happen with a wired connection. I have tried three different wireless routers, and each one behaves the same, so I'm pretty sure that the router hardware is not the source of the problem.

When I close either IE or Firefox, an instance of the iexplore.exe or firefox.exe process is usually left running. If so, it must be manually killed. Sometimes the process will not die, and restart is necessary.

When I try to restart or shutdown, it usually takes a very long time to do so. Often I must simply power off without properly shutting down.

When I restart, Safe Mode w/Networking will usually be better, and sometimes I can restart into normal Windows mode. Other times I have to start with "Last Known Good." There seems to be no pattern as to which startup mode works best, though Safe Mode is usually the one that will work.

I'm running Windows Defender, and Avast! antivirus, and Spybot S&D.

I have cleared all IE and FireFox history, cookies, etc. I've run Windows Disk Cleanup, and Disk Defragmenter.

I am no longer using Verizon FIOS, nor any Symantec product, though I notice some entries from both in the HiJackThis log. I formerly had Norton Internet Security installed, but I removed it. There is likely some remnants of Symantec files on the system, since it's difficult to uninstall it all.

One other problem, possibly unrelated but definitely annoying, is that my cursor is moved from time to time. It acts as if I have pressed the left mouse button, which then moves the cursor to another place on the screen. No other keystrokes nor any evidence of "remote control" has been noticed.

I've searched through the event viewer, and found an entry that is suspect: dcomscm.exe. I'm not sure why that would be in the logs, since I don't (think!) I have SQL running. There is a software package that Sony initially installs on the system that has to do with SQL, but I'm not sure about what it is or does.

I've just removed GoogleUpdater.exe and GoogleUpdate.exe. I've also just installed ZoneAlarm. Previously I was using the firewall that comes with XP.

Since removing GoogleUpdater.exe and GoogleUpdate.exe, the system seems better, though only with FireFox. IE Still hangs.

Thanks in advance for your help!

Verizon FIOS, google says it might have had McAfee?

And you had norton's also, both take special uninstallers to remove all the components.

We can't analyze HJT logs in this forum

We are here to sort out problems like yours where software may be clouding the picture, but we need to eliminate malware from the equation.

No. Try not. Do... or do not. There is no try.
