If/When the program gets too heavy on resourses when it starts to miss lots of samples (more compared to other AVs) when the Virus , Partners or Support team are becoming slow or when it seems they have gone on quite a long holiday when the AV vendor (the company) has no strategy for future development and it seems to be going nowhere , when there is no innovation when there seems to be lots of small issues : this is when I change antivirus and the AV company
I really support this idea, a future strategy/plan tends to show the people working there enjoy what they are doing, they want the product to evolve and succeed, whether it is for money or protecting the user, they are still enthusiastic in their creation.
Does not stop malware infection....one of it's main functions. Heavy on resources is another big no, no too. Really there were a lot of reasons there to move on, but number one would be lack of preventing malware.
I stopped using AV's and the main reason is that they use too much resources. Furthermore, I think I can decide whether a file is safe or not. And if I really want to play around, I still have an option of virtualisation or backing up an image.
If the AV cannot be activated on multiple partitions then this is the "Kiss of Death" as far as using it.
I voted other as I have dropped 3 products this year for the same reason. Just plain too buggy to use. BSODs, blocked network connections when they shouldn't, GUI crashes, etc. I am tired of all of the poorly written software that cause me more problems than they solve. Every time they start to get it stable and working somewhat well it is time for next year's version and it starts all over again. I feel like a permanent beta tester for these companies.
i like light very light on my computer, and i like it never slow the internet , i like it to be good detection and find any virus in my computer , thats why i use comodo internet security now
