At this moment of time, I'd agree that it's best to stay with v8. There's many bugs yet and some are annoying (such as the VPS ad bug). So stick with 8 for a while longer until the bugs are ironed out..
Alikhan, we are not aware of any important bugs in avast 2014 R2 release (9.0.2011). Any reports of such issues are welcome.
Of course, it's a software therefore there are always some bugs however we are talking about bugs that affect important functionality or wide audience...
I would agree that most of the bugs don't affect important functionality but the most irritating fact is that when the bugs are reported on the forum/feedback, there's no response from avast! at all.
For example, not receiving the VPS notifications was reported as a bug at BETA3, no one has commented on it.
The current release stops Outlook 2010 from receiving/sending emails.
The firewall is still not fully compatible with Java sites. I understand that it's been recoded but it puts alot of users off.
Since the new transparent proxy has come in, a lot of people can't browse the web. Not everyone is capable enough of fixing the issue. I've seen several people who can't browse the web due to it.
The paid version has got ads in it... seems like a cheap marketing trick. I'd understand in the free versions but the paid I think is unacceptable.
In this version, the RAM usage has gone very high.. it seems like there's a memory leak. It has gone up to 140mb idle. I know that it's still low on the CPU and I/O read but a jump from an average of 10 to 140 doesn't seem right...
The AOS plugin still has problems. Makes web browsing slow and in some cases impossible in Firefox and IE11. I don't even need to go into more depth with that.
Since the release of v9, the amount of false positives have increased significantly.
There's been a lot of errors with "offline" installations NOT working and the "online" installer working.. there's been no response of that. I myself have 3 laptops which don't install using the offline installer but work during the "online" installer. I suppose this has to do with the SFX.
Version 9.0.2011 causes videos to lag/stutter on Youtube while using the transparent proxy, reverting, fixes it. On some occasions, it would block the videos completely. Again, by disabling Avast, the issues were fixed.
I'd agree that the majority of the bugs would be fixed by a clean install but many novice users wouldn't know that. Even a simple "we're aware of the issue" or "fixing it" would let the users know. A lot of these issues have been spread around on the forum in several topics/posts. To end with a positive v9.0.2011 has fixed alot of the bugs but still there's room for improvement.
