Which antivirus to choose for windows7?

Question

Windows

Recently I picked up a virus that in all browsers replaced the start page with my own and changed the search engine, and I didn’t download anything, I just watched movies and sat on social networks. After that, I thought about installing an antivirus, but which one should I choose? My computer is not the most powerful - Intel Core i5 U520 1.07GHz, 2GB of RAM. Maybe there is a good, free antivirus, undemanding to the system?

Answer 1

Of course, I'm only for using my hands and head, but I'll give you advice.
The described actions of the "virus" are regulated by the work of browsers, and therefore are not subject to protection by antiviruses. Therefore, now no antivirus will give a guarantee of protection against such actions. My experience shows that it is.
If you really want to put something free. Install avast, there is imaginary browser protection from third-party plugins. There is also an outrageous application from Yandex, which does not allow you to change the default page. It itself is a virus, but antiviruses do not consider it as such.
