Hi Asyn - my mistake - I did in fact have the 2393 version. For some reason Revo Uninstaller is showing the old version - that's where I took it from . Additionally , I am still getting a slowdown , here and there - but not like before . A question - can I download an old version of Avast Free from somewhere , from like a few months ago , when I had no problems , and install over the current 2393 ?
