I have a laptop running Windows XP 32-bit. It was infected and the McAfee anti-virus I had installed was not removing the virus. Yesterday, I uninstalled McAfee and installed the latest version of Avast (v7 )-free version. I got a memory exception at the end of the install which i momentarily ignored. On rebooting the machine, I got the Blue Screen of Death. I rebooted the machine again, and cleaned the system with Avast.
However, I have the following symptoms:
1) There is a yellow triangle with an exclamation on the avast icon in the taskbar constantly.
2) More importantly I am not able to register my installation of Avast.: The registration page never shows up. The page has a spinner for a few seconds and then closes.
I also have a desktop running XP 32-bit that was also infected. I did the exact same thing on that machine too. I did not get a memory exception or the BSOD. It shows neither of the symptoms 1 or 2. I am able to register on that machine.
Could some one please help me debug this issue? My laptop contains crucial information and is absolutely essential for my work and I am very nervous about this.
