there is little we can do to help.
What does this popup look like? Where on the screen does it popup? (eg bottom right hand corner near the clock?)
Does it popup ''only'' when your screen saver is on, or at other times as well? What other times?
Does this start as soon as you turn the computer on and Windows has loaded? If not, when does it start?
Do you use a firewall? If so, is it configured to alert you everytime a hacker attempts to access your computer?
What do you use to protect your PC from viruses, spyware and adware?
What are the specs of your computer, and what ISP connection do you have, eg dialup, broadband?
What processes are running in the background? Right click the Taskbar, and select ''Task manager'', then click the Processes tab. Go here;
to check what each process does.
What programs are loaded at startup? Goto Start > Run and type in ''msconfig'', (without the quotes), and check the Startup tab.
I'm running Windows XP. Every ten or fifteen minutes a program pops up in the background, for about 1/2 a second, then disappears. It disrupts my screensaver. I have no idea what this is, or why it pops up. I thought it was an Outlook automatic mail download but I disabled everything I know of with Outlook and this problem still persists. Can anyone offer any help?
