Even when I try to open MS Excel it opens a popup, that's troubling for me.

If kaspersky cant certify a Microsoft software that has been scanned during installation and multiple times later is clean and needs to query the user each time then that AV is not for me.

Thats the reason i shifted to less intrusive and more clever security suite. OTOH kaspersky is known to be better at catching rootkits and new types of malware but i dont visit warez sites, so for the time being i will stick with Eset.
