... Let me tell you what's happening in quite a few words: every second boot, XP reaches the desktop, resident progs. start to load,..., and there it is, XP is frozen, I get the hourglass when pointing the cursor at the task bar... just got to cold reboot and it should boot ok. I point at Kaspersky Antivirus Personal Pro because the problem started to show up right after I installed it. Antiviral ToolKit Pro was installed before (previous XP install) and worked flawlessly. When I uninstall KAV Personal Pro, and reinstall AVP everything's ok ! To be sure, I put back KAV and here we go again: XP freezes at the very near end of loading the desktop ! I must mention though that sometimes, after 10 or 15 minutes, XP show me it is not frozen anymore !!! But it's rare ! Is it KAV itself, or a parameter whithin it ? Please, help me find out ! Thanx.
