I'm going to move this back, at-least for the time being, since I don't see any malware there -- and treat it as a "performance" issue.
Please answer any questions below which you have not already answered -- also can you describe the "error" sound you hear?
Review item 6 in the list below with particular attention.
And do you see any repeating error messages in the Event Viewer (run:
eventvwr.msc) and look at both the system and applications logs.
For any repeating error, double click it to read the description, and use the double-paper copy icon to copy it to a reply here. Just do a select few of these.
Look in particular for "Disk" errors in the system log which might indicate bad blocks on the drive.
PERFORMANCE QUESTIONS:
0 > when did the problem seem to be begin?
1 > is it very slow to boot up?
2 > do programs open slowly?
3 > does the same behavior occur both on and off the internet. Or with no connection at all?
4 > does it matter how long the system has been on, and does a restart improve things?
Slow performance issues can often be due to overheating, so if the system is faster after it has been shutdown for a while and then restarted -- that would be especially suspect. To check for possible problems here, shutdown, open the case and blow out any accumulated dust. Then turn it
on and check to see that the fan is working. Sometimes it helps to physically clean the fan.
If a laptop, check to see that the vent is clear of dust and verify the fan is working. Temps and fan speed can usually be monitored with
SpeedFan (except on Dell desktops), a free utility.
5 > if you do a ctrl-alt-del, do any processes show excess cpu usage, other than System Idle Process?
6 > If you open the Device Manager (run
devmgmt.msc) and select the entry for IDE ATA/Atapi and select the Primary IDE > Advanced Settings, does it say the "
current transfer mode" is Ultra DMA or PIO?
If it says PIO or even just DMA (rather than “ULTRA” DMA, first ensure "Use DMA if Available” is selected, then select the driver tab and uninstall the driver and reboot. Then check again.
Alternately you can run the script on this page >>

COMMIT CHARGE
Do ctrl-alt-del to open up the task manager. Select the "performance" tab. Let me know what you see under:
Physical Memory Total: this is your total installed ram -- "physical" memory
Available: this is the amt of real "physical" memory presently uncommitted
Commit Charge Total: this is the combination of total physical and virtual memory currently in use
Limit: this is the total physical and virtual memory available
Peak: this is the most you have had in use in this session
