Sounds similar to the problem I experienced, see forum item

I found after I manually removed 4.8 and did a clean install it all now appears quite stable.

but my registration details were in myavast 4.8 ..and in avast website only they told me to install 5 without uninstalling 4.8

Needless to say if they told you that they were wrong. No matter which you put back you need to uninstall any others and get rid of all folders and files under the folder Alwil Software.

They weren't wrong as the 5.0 installers a) retains information about your registration and uninstalls 4.8, check the avast! 5.0 FAQ - General - http://support.avast.com/index.php?_m=knowledgebase&_a=viewarticle&kbarticleid=455&nav=0.

No matter if you have to do a clean install for whatever reason there is a way to convert your old license key (you would obviously have to have retained the email with that in it).
- avast! 5 Pro license convert from 4.8 Pro license. Try http://www.avast.com/resend-license.php now, fill in the form giving your email and 4.8 Pro License key and they will send the new license file to you (presumably it will check you have a legit 4.8 Pro license first).

It took my 4.8 license. But after another crash or two, I went back to 4.8
