I'm trying to remove kaspersky antivirus free from my computer but I'm not able to - if I go to apps & features and try to remove it there, I'm receiving error as on screenshot below: I tried running kaspersky installer to remove it but when I choose 'uninstall' in installer window it shows similar error and just crashes, how could I remove it?
Try to remove it from Control Panel > Programs and Features, and follow the prompts.
See the documentation How to remove a Kaspersky Lab application.
If this does not work, try the Kaspersky Kavremover:
Kavremover is a free tool for removing Kaspersky Lab applications from your device safely and in full.
Have you considered 'overwriting' it with a new installation of Kaspersky? Post that just try unistalling it.
That would just install it once again on top of the existing version and perhaps fix any installation problems that is preventing you from uninstalling it.
I'm guessing you're doing this on admin rights.
Another option I could think of would be to use the Safe Mode and then uninstalling it from there.
