Did you resolve the problem with Windows Media Player that becomes red ? Because it comes from AVAST 6, when I uninstalled AVAST 6, Windows Media Player went to its normal colour.
And I had a problem with the search function of windows explorer : when I opened the search page, it staid blank.
I noticed another problem that was with all AVAST : it makes YouTube slow. The video "buffering" is slow and when the video is playing, it stops 5 - 10 seconds later. With KASPERSKY, the videos play perfectly. I am sure of that because I have a high connection 10 mb since november 2008 so I can watch youtube videos since this date ... and I already had AVAST and since november 2008, so since I can watch youtube videos there are problems when playing Youtube videos. And there are no problems with KASPERSKY now.
To be honnest, because of all these problems I uninstalled AVAST and I installed KASPERSKY but KASPERSKY is too heavy for my computer. So if all the problems with AVAST 6 could be resolved, it would be great. I didn't buy any licence for KASPERSKY yet, there are 27 days remaining before the free version stops, so it would be great if the problems could be resolved

I wanted to install AVAST 5 again, but I don't have the installer anymore and there will be certainly no infections updates anymore very soon.
Thank you very much in anticipation
