I got a virus a couple of days ago and had to re-install XP. Since the re-install, I've been getting tons of "Windows Install" pop ups while I'm online. Most of which occur when I click a link. Some of them come from no where, and they come in bunches. Each one goes away on their own after about 5 seconds during the "preparing to install" phase. I don't know what is causing it. I've never seen this happen before. Can anyone out there help me out?

Hi Joey -- Welcome to PCHF.
I'm going to refer this to the security team as you might still have some infection.

Please download HijackThis. It will create a directory folder for you in C\Program files. Run a scan and save the log file. Post the whole log file here. Do not fix anything since most of them listed there are harmless (some are system required). This program will help determine what,if any, spyware/malware is on your computer.
