I am running Windows XP Professional, and up to recently was using AOL and the McAfee Security that was bundled with it. I attempted to switch over to Kaspersky Internet Security 2010 (uninstalled McAfee), and I was able to install it but could not activate the trial license. I kept getting an error message "Activation server unavailable" even though I was online and was able to properly load webpages (including the Kaspersky homepage).
Suspecting a virus, I booted up on Safe Mode and ran gmer.net, which found no rootkits. I then ran MalwareBytes, which found about 6 infections and cleaned them. I cleaned my registry, and then attempted to activate Kaspersky again, to no avail. I tried to run the eSet online scanner, but it wouldn't run.
I booted up again on Safe Mode and uninstalled Kaspersky Internet Security 2010. I then ran Kaspersky's Virus Removal Tool, which found 6 more infections and cleaned them. I then tried to run eSet's online scanner, which finally ran and found 3 more infections.
Since I uninstalled the existing Kaspersky IS 2010 program in my computer, I now went to re-install the program. It downloaded properly, and unpacked, but after the "Preparing to Install" Windows Installer window pops up, it disappears and nothing happens. The installation seems to simply abort.
I am running out of ideas, and any help would be greatly appreciated. How do I find out if I am still infected, and what the infection is?
