Downloaded 6.0 today after using 5.xxxxx for about 8-9 days, I had just started using Avast. After download it asked for restart, I hit restart, and computer (WinXP) just started recycling through Restart. Never completely booted-up, it would get to the Win XP log on window and after a few seconds it would shut-off and start booting-up again on and on and on…
I did a soft boot and uninstalled 6.0. Started-up fine.
Tried re-install of 6.0 and the problem started again. I re-installed 3 times w/ the same results. If I didn’t restart, I couldn’t reopen any browser Window once I closed the window I used to access the new download(got a double error message), and when I restarted after a complete shut-down the recycling started again
How did you install avast 6, update from avast 5 User Interface or clean install ?
Now you have been back and forth a few times it may be best to do a clean reinstall.
This assumes you are using free version:
Download the latest version of avast, 6.0.1000 http://files.avast.com/iavs5x/setup_av_free_eng.exe and save it to your HDD, somewhere you can find it again (if you didn’t save your last download). Use that when you reinstall.
Download the avast! Uninstall Utility, aswClear5.exe find it here and save it to your HDD (it has uninstall tools for both 5.x and 6.0.x).
Now uninstall your current installation of avast! (using add remove programs, if you can’t do that start from the next step), reboot.- 2. run the avast! Uninstall Utility from safe mode, first for 5.x if previously installed and then for 6.x, once complete reboot into normal mode.- 3. install the latest version, reboot.
Hi! I am having the same problem, although I have been using avast 5, and before it 4, for years instead of days. I think it has to do with the fact that I am running Windows XP SP1 on this system. I can not upgrade this computer to SP2 or higher because I have some older software, games, that can not run using Windows Media Player 9 or higher. They require version 8. I did not check the web site, which states that it only supports Windows XP SP2 or higher, until after I had allowed Avast! 5 to upgrade and found that windows could not start. I am surprised that Avast! 5 did not notify me of this new system requirement or warn me that my system did not meet the minimum requirements for Avast! 6 before it performed the upgrade. I have been looking around for the last version of Avast! 5 so that I can download and reinstall it on this system, but have not found it as yet. Hopefully a link can, and will, be provided.
I encountered the same problem when I tried to install Avast 6 on a fresh Win XP SP1 computer. So a word of caution to anyone with a PC that is still using XP with SP1 or older, don’t upgrade to Avast 6 as it will wreck havoc on your system. Stay with Avast 5 or update XP to SP2 first before installing Avast 6.

BTW, XP SP1 has been unsupported by MS for ages and XP SP2 since July 13, 2010. You are not getting hotfixes for critical Windows vulnerabilities. You seriously can’t rely on an AV or security suite to make up for this fact.
Working on SP1 from 2004 with same soft (except Firefox and Avast) - never got problems. Avast was exellent free antivirus which worked fine on old OS.
