i don't understand why so much antivirus had this type of problems in xp
this is really old, all the tricks should be known now 
You make a really valid point µT6, Win XP SP3 must be the most "Patched" operating system there is !!! About 12 years of weekly/monthly security updates. It should be bullet proof, ...
I've setup a XP machine at home which was my mum's, which she totally got scammed by a hoax caller claiming to be from Microsoft. She is 80 and did what the guy said, he threatened; "Give me your credit card details or I will wipe your computer !"
She was so confused only just been online a month that she said, "no" to credit card details, but followed the instructions which he gave. I really don't know why she didn't just hangup, but was just tired I think.
I've been looking it over and all the drivers were wiped, plus the operating system. I want the DVD writer to work, which will happen.
Anyway getting back to good ol' Kaspersky, and Windows in general, when I reinstalled XP I was just blown away how complex things had gotten with Anti-Virus software in the few years I haven't been using it.
I've always used Avast! free Home edition as the resident AV, and a on demand scanner, Malwarebytes-Antimalware, which is very excellent for free.
I think it was about 5 years back i bought a license or three for Kaspersky and got so pissed with their Australia/New Zealand office that they shut down the office for a week due to my complaints.
To install the bloody thing you have to un-install every little security App, program, basically make it a clean install, or it wouldn't work, which probably caused this recent ceasing of function which locked users out of the Web.
Anyway it's a crok of xxxx. I'd think at least 50% of my time was doing updates for Kaspersky, configuring it, re-installing other detection programs, installing HOSTS files, it just goes on, and on, so i spat the dummy on the Forum and had it closed down, as I said about 5 years ago.
I believe that you work with Windows commercially fixing systems (?), you would understand what I'm saying.
So this recent, "Oh i'll just setup XP for a laugh" was crazy. Avast! is too complex, everything robs your time with security updates.
Therefore your normal Joe doesn't do anything, there's Malware attacking Win computers day and night worldwide and no one can give a xxxx.
Eugene Kaspersky thinks he's the world's leading expert in securing windows comps' and he earns millions of $$$'s stooging just as much as hackers, giving a false sense of security to customers who in Menotu's quoted article got shafted without any connectivity as the Security is so complex.
Kaspersky sent out a buggy signature update Monday night that largely paralysed countless computers running XP. The bug apparently made web protection so strict that the Kaspersky products quietly blocked almost all internal and external network connection attempts. The virus scanner also pushed CPU utilisation to 100 per cent as soon as a user opened a browser.
The company did release a fixed update just two hours later – but that wasn't particularly helpful for the computers that couldn't download it because of the strict blocking. It seems users weren't completely cut off, though, with many saying that they could still load Google and Yahoo.
It just is not Cricket, with Hackers on one side, and AV companies on the other, the consumer is a sitting duck, Billions of $$$'s get scammed regularly.
Windows should be taken offline; it's a menace to the world's function, and of every country and person on this planet, and I'm not kidding around.
