Windows 7 Pro slow after sleep

Question

Hi Guys.
This is driving me mad! I have a Lenovo Thinkcentre Edge 71 1577G1G running Windows 7 Pro and every day it starts Ok from sleep but after about 3 minutes its starts to go slow and will not do anything hardly for around 30 minutes, all this time the hard
drive is whirring away and sounds very busy. I have uninstalled Norton which made no difference and there is loads of space. CPU usage in Task Manager is low at around 0-10% but it still won't do anything. It is also slow to respond if left for around 1 hour,
although sleep is set at 2 hours. I have set everything to max performance and removed Lenovo's power saving as I read somewhere this can cause conflict issues all to no avail.
Any ideas please?

Answer 1

I can tell you this. Norton Internet security is certainly not willing to play nice and hasn't been doing so for quite a while, but because of Norton's aggressive monitoring, I surely cant tell if it is reacting to something that shouldn't be on the system
or being merely overly aggressive, but I suspect the latter.
Secondly, I seem that windows firewall is running and it shouldn't be, because by default, it should have been turned off, the moment Norton or any other third party Antivirus was installed. I suspect that the combination of Windows firewall and NIS, is
probably leading to some conflict and playing a role in slowing performance.

I suggest you remove Norton, install, update and run a complete scan with Microsoft Security essentials. When done scanning with MSE, Download, install, update and do a complete scan of your system with Malwarebytes free, for good measure.
Note: You can keep MBAM and occasionally use it as a "second opinion" scanner. Remove any and all found, reboot and repeat the scans until nothing is found.
Norton Removal Tool.
