Windows XP, a Sony Vaio laptop not more than 1.5 years old (Intel Dual Core, etc.). Mostly use Firefox browser, but also Safari and IE, on occasion.
For about a month now, I'm being awakened in the early morning hours by the sound of the computer 'running' or 'ramping up'. Like the fan is on high. When I open the lid and open task manager, I see that many of the processes (almost all of them) are pulling down about four times what they usually show from the central processor. Let's say under 'normal' circumstances a process might use up 5,490 KB of hte CP, but shows 23,000KB at 6AM. ALL of the processes look like that at 6AM. I don't get it.
I have a VIPRE (Counterspy Anti-Spy and Anti-Virus) scan scheduled for 1AM. I run AdAware when the mood strikes, usually every few days. I uninstalled SpyBot after reading reviews and concluding it was too ineffective in its current iteration. I have Windows updates set to automatic. I download all security updates when asked to do so by Hewlett Packard (for printer), Adobe Flash, etc. Other than VIPRE, I have nothing scheduled for 6AM. Even if I did, why would that make all the processes 'ramp up' like that?
Once it starts, the only way I can get this beast to stop is to shut it off, which I do. Then, when I turn it back on, the processes look normal again. The other thing I notice, is that when I reboot the computer, I get a warning message that 'no firewall is turned on' for a brief few seconds. Then the warning goes away as the computer reboots. I checked the settings and a firewall IS turned on, of course.
Question: Is someone else using my computer at that hour? I looked at the start=up menu and saw a remote assistance icon. I checked properties under 'my computer' to ensure that the 'allow remote assistance' settings are unchecked, and they are.
Any ideas on what to look for? Maybe I should 'turn off' the computer every night, instead of letting it go into hibernate. I don't like to do that because of hte extra time it takes to boot up again in the morning. Plus I believe I was told at one time that that wasn't necessarily 'good' for the computer (to shut it off every night).
