I was suffering with slow boot times and went as far as reinstalling Windows XP and going through all the processes of getting my PC back to health again only to find it was still having slow boots. I suspected maybe a imminent hard drive failure, but then thinking that Avast was updated and had started the slow boots around the same time I uninstalled Avast to see what the boot time was like after.
The result was from the 5ish min boot up that it was, to a "Normal" 15-30 sec boot.
I have been a user of Avast for some 5 years and have been very happy up till now. Don't get me wrong I'm not complaining about the trouble free previous 5 years, but there just seems to be a problem with this latest version.
At the moment I've no A/V installed, I wouldn't recommend running without, but it seems I can't recommend this Version of Avast.
Hope this can be fixed quick
