Have delayed installing 8.0 due to problems reported here. Any problems with your install?
I'm running Win XP Pro SP2. I had not planned to upgrade because I seemed to recall reading about some users having problems with 8.0. But, when I received a notice today from AVG that 7.5 will no longer be supported after May 31, 2008, I decided to go ahead with the upgrade.
I did not remove 7.5 before installing 8.0; this decision was made after reading on grisoft.com that installing 8.0 will remove any previous versions of AVG. At one point, the installation appeared to have encountered a problem. Sorry, but I did not make note of the exact wording of that message. Whatever it was, it did not prevent a continuation of installation; as I recall, I had to click OK on some prompt related to the message and then the installation proceeded to completion. Again, sorry about the vagueness of this info; I know it's not very helpful.
Once the installation finished, I was prompted to restart my computer. I also still had to get updates for AVG; it's main panel warned me that I needed to get updates; this appears to be a one-time catch-up. I have confirmed that AVG is monitoring my email. I use both Outlook and Outlook Express and it is inserting the notice at the bottom of incoming messages that no virus was found in the message.
I read the other thread you posted and I can say, in spite of the large download file, version 8.0 is not behaving like bloatware. In fact, I noticed improved performance over 7.5. Applications (not just Word and Excel) are launching faster. By the way, Add or Remove Programs panel shows AVG Free 8.0 weighing in at 26.69MB.
If I encounter any problems in the next few days, I post back with details.
Edit: After the installation, an old folder named Grisoft and two sub-folders remained in my Program Files folder, but they were empty. I deleted the folders. I then ran CCleaner's registry scan. It found 10 items, some of those were AVG; no surprise there; that's what registry cleaners are for, right?
