Very slow computer....please help..
 

Out of the blue, my computer is really really slow. When the Internet Explorer is started up, system resources go up to 100%, when I close Explorer it goes down to 1%. I've tried getting rid of spyware, virus scan, defrag, but to no avail. This laptop on the same network is fine, so I don't know how this has happened. I've just ran Hijack This, and here are my results:

Can anyone help me? The problem appears to be with Norton I think, but I'm not sure...
Thanks

Re: Very slow computer....please help..
 

I've got the same problem.

It's caused by symproxysvc.exe hogging the CPU (that's Norton Firwall's HTTP proxy). I believe (but haven't yet checked) that it got updated by LiveUpdate.

I haven't had the chance to report it properly to Symantec yet (and as I'm running NIS 2002 I think it's no longer supported?), but I've temporarily got round it by disabling the firewall (I'm behind a router so not too worried).

Just wondering whether to dump it for something else.

Re: Very slow computer....please help..
 

I'm running 2002 too...

Re: Very slow computer....please help..
 

Disabling firewall has done the trick for me too... oh well, bye bye Norton by the looks of it!

Re: Very slow computer....please help..
 

but please get another f/w solution as soon as possible , otherwise you might pick a trojan up quicker than you might think :disturbd:

Re: Very slow computer....please help..
 

Indeed - get Zone Alarm (free) or something...

Re: Very slow computer....please help..
 

kerio is a good free choice :tu:

Re: Very slow computer....please help..
 

Also - how up to date is your anti-virus?

Re: Very slow computer....please help..
 

It's a home network so he's behind a router/NAT/hardware firewall

Re: Very slow computer....please help..
 

F-Secure and McAfee are both good imo

Re: Very slow computer....please help..
 

Would advise against Zonealarm. If it goes wrong it can truly **** your computer up good and proper. Use XP's firewall, does the trick and just as secured (try shields-up). If you ever have to un-install ZA make sure you read google/Zonelabs for the safe removal options. CG

Re: Very slow computer....please help..
 

good point :tu:

Re: Very slow computer....please help..
 

There is no way that the XP firewall is as secure as ZA Pro, XP blocks incoming port scans but cannot prevent anything nasty on your system trying to get out.

ZA Pro takes a bit of tweaking ( use Robin Walkers excellent advice) to get it set up. If it wasn't for the little blinking icon in the systray I would not even know it was there.
