First of all, it is one of the worst experiences that I have to write these into a 90's style forum page instead of receiving a decent support!
First thing I experience after installing Avast was random annoying Internet disconnection, which happens to be fixed only after restarting my device, but only sometimes! I tried to shut down shields (which I shouldn't) however it never became a solution.
Secondly, Avast installed an unnecessary browser into my computer which I don't use and will never use, that pops up any time.
Any solution?
