Hi All

I seem to have caught about:blank and it's causing me sleepless nights. I've followed some of the posts here and have downloaded many of the tools suggested; however specific advice to each poster seems to depend on the contents of their hijackthis log, so here's mine. All input gratefully received. BTW, I'm not sure when about:blank first arose, but Norton AV didn't catch it.

Regards

Nick

An update on this - what I think is happening is that whilst the machine still functions, processing time is being hogged by some process or processes associated with the virus. Running Windows system monitor shows a background (i.e. no user activity) usage of over 80%, occasionally spiking to 100% for several seconds, and then when the user tries to do anything it goes straight to 100%. What does work works extremely slowly, and what doesn't work just hangs up the machine. Sometimes attempts to launch something result in an error message stating there is insufficient RAM available - the machine has 256MB. The poor old PC just doesn't have enough time or resources to do what it needs to do. Comparing this with another machine, the processor usage is sub-10%. Both machines running Win 98 SE, similar h/w spec.

All input gratefully received.

Hiya,
Sorry about the response time. If you still require help could you post a fresh log because the infection may have morphed.

Hi Owen

Things got so bad that we had to take drastic action - which was to move everything from the broken machine (PC1) to the other machine (PC2). Although PC2 does not show signs of about:blank, it is, since the transfer, still running slowly and losing resources over time. I am unsure now as to whether this is some other form of infection, or just a problem associated with Norton Internet Security hogging resources. PC2 is a Dell Optiplex GX110 running at 667 MHz and with 512MB RAM. PC1 will now be the subject of a completely clean reinstallation with a larger HD - which it was in need of anyway, so the PC1 problem has effectively gone away but been replaced by performance problems on PC2. So anyway, here is a hijackthis log from PC2.

All input gratefully received.

Regards

Nick

More info - this looks more & more like a resource problem. On reboot the system resources free shows around 25% on Resource Meter, and drops thereafter, often falling to 1%, 2%, 3%... What is hogging resources and how do I analyse this and find a fix? I have to reboot hourly.
