and thanks in advance for any help / feed back
Ok a few years ago just at the start or windows XP pre SP1 I got badley infected with sassa virus and count down timers that deleted the ntldr file from the root of c drive, it caused all sorts of problems at the time spread over the whole network on every machine / server.
At the time I cleared down every machine re formated every drive and cleaned each machine one by one to clear this nasty off every machine,
That was years ago and since then we have had sp 1,2,3 for windows XP
I still suffer with a very strange side effect from the days of being infected, which is all my machine on my network vary in speed / how fast they feel when clicking in windows, even freshly installed machines with very little software and no anti virus software still feel as if they speed up and slow down, sometime they feel real fast other times they just feel real sluggish ?? for no reason
and it all seems to go back to the time of being infected years ago, It may not be related ??
It almost feel sluggish like a remote admin program has slowed down the machines at times, though I have wiped and reinstalled windows many times,
1) could anything have been left behind even after trying most new antivirus programs / rootkit / etc. ?
2) could it be related to my internet connection quality, can this slow down and speed up the feel of windows ? I am on a 50meg Virgin service but the DNS can be very slow at times (Slow webpage)
3) In the past other people have said check your mains supply ??? but I don't feel this holds mauch water as the PC power supplies are designed to work from 90v - 260v !
4) I know sp1 slowed down and did many major changes to XP and I can only imagine SP2, 3 followed similar, could it be from sp1 this issue has ocoured ?
Its hard to describe but sometime I turn on my machines and they fly in speed and other times they do not for no reason that is apparent ? I have tried every type of antivirus/rootkit and so on and nothing is ever found,
This has been going on many years now and I would love to get to the bottom of it,
I also notice it on my window 7 machine, sometime fast sometimes slow, Its comon on all machines in my home, and I know someone will say it the mains power, but I have done test and all looks good
Could this be some clever nasty or maybe my internet provider causing a sluggish feel with my networked machines ??
Any help will be very much appreciated
Even tonight my machine feels much faster in every way than it did the last time I used it ?? its crazy why is this?
even when it feels slow NO services are being used in task manager i.e. idel is at 99% and this has no antivirus as I have just installed windows and all updates ??
