I have a Dell PC running Windows XP, Service Pack 3. It has gotten very slow to start. When it boots up, it says: "1 program running." I think stopping it will speed things up, but I have no idea what it is, where it is or what will happen if I stop it. Also, I get a RUNDLL pop-up: "Error loading C:\Program Files\Common Files\Paretologic\UUS2\UUS.dll." What do you suggest regarding the mystery program running at startup and the error message?
The "1 program running" is most likely something left under a different user login that did not log out. Try this to stop the pop-up: Click Start, Accessories, System Tools, Scheduled Tasks and delete any tasks that references Paretologic.
For other startup issues, click Start, Run, type MSCONFIG and click OK. Click the Startup tab. These are the programs that start up automatically when you boot. Many of them are not necessary. Every PC will be different, so you will have to do some digging to find out what these programs are if you don't recognize them. Each can be prevented from automatically starting by unchecking it. Some other ideas: 1. Do a hard disk Defrag. 2. Make sure that the PC's fan is not caked with dust. If it is, a blast from a can of compressed air (available at any office supply store) should fix it.
I installed Microsoft Security Essentials. The icon on my desktop is AVG1120. Is this Microsoft Security Essentials? (I am using Windows Vista.)
No, it's not. It is the AVG Technologies free edition of their antivirus. If you have already uninstalled it, then just delete the desktop icon. Otherwise, go to Start, Control Panel, Programs, Programs and Features, Add Remove Programs to uninstall AVG. Antivirus programs don't play well with each other and only one should be installed.
