Hi. I installed Avast 4 Home a few days ago, and I LOVE WebShield! But that same day, Windows Explorer started crashing on my system. ("Windows Explorer has encountered a problem and must shut down...") I've uninstalled Avast, and reinstalled AVG, but the problem persisted. Then, through reading this forum and doing some checking, I discovered that not only in the Avast screensaver still selectable (although I can't find the file, itself), but aswBoot.exe and aswRdr.sys were still on my computer, too. I've deleted aswBoot.exe, as another thread on this forum has indicated it was safe to do so, but have left aswRdr.sys in place until I get confirmation that it, too, is safe to delete. Windows Explorer still crashes.
A little background: I've been using Windows XP for all of two months. The computer I bought came with Norton Internet Security installed. When it gave me problems, I switched to AVG, then the recent WMF exploit prompted me to switch to Avast. I uninstalled each AV program, and restarted, before installing another, but I did so through Add/Remove Programs and looking for leftover folders in Programs and in Application Data, not through editing the registry (which sounds fairly intimidating) or through any special removal tools (which I've only become aware of since my Windows Explorer problem began). Is there any possibility that leftover bits of Norton or AVG could have conflicted with Avast and produced these crashes? My system ran very smoothly before Avast was installed, and I'm at a loss for any other way that the problem could have started.
I really don't want to have to resort to system restore. I've emailed Avast support, but haven't heard back yet. Any advice you could provide would be appreciated.
