Avast Free Version 6.0.1

[christine74]

I have been using the free version of Avast for the last 2 years and haven't had any problems. I am presently using version 5.1.889 (with the latest engine and virus definitions) A few days ago I tried updating to version 6.0.1000 and once the update was completed , it rebooted for the changes to take effect . However my PC wouldn't start after this ( It would just stay paused at the opening Windows XP screen). Therefore I went to safe mode and uninstalled it. Does this have to do with the fact that I still have Service Pack 1 only on my system? Also can I still keep using my 5.1.889  version with the latest engine updates without having to install version 6?

Can't say with 100% certainty, but that could be considered a strong possibility, yes.

Also can I still keep using my 5.1.889  version with the latest engine updates without having to install version 6?   

Yes, you will still get definition updates.  I feel obligated to inform you that there is inherent risk to not keeping up-to-date with programs, especially your AV.  But you have already crossed way over that line still running ages-old SP1 for XP.

Hello and welcome to the forum christine74!

For avast! 6 you need XP with SP2 or higher. For the security of your PC you should update your XP to SP3 immediately!
