So last night, I downloaded on my Windows 10 PC what I thought was a Minecraft setup file from Kickasstorrents (a mirror site). When I opened it, a window came which said it needed to verify if I am a human and told me to click on a button 'Begin test' which was supposed to give me a password that I would have to submit in that window. I clicked the button and it took me to a webpage. I forgot the exact address but it had the word 'humantest' somewhere in it.
Soon the browser (Chrome) was closed automatically. When I reopened the browser, I found my homepage has been changed to a weird-looking search engine site. My default search engine has also been changed. Furthermore, an extension was installed, which I removed from Chrome promptly.
But there were more symptoms. Porn ads would pop up on my desktop every few seconds. Windows asking me to install some even weirder-looking programs would also come up. Then ta blank window would come up which had the title of something like 'News'.
I was frustrated, because I never installed such a virus (or malware) in my life. But I decided to try a system restore. I restored to a point created the day before.
After the restore was complete, all those ad popups and program installation windows were gone. The only thing that remained was the default search engines on Chrome and I changed that manually.
Is anybody familiar with such viruses/ malware? Is there any chance the virus is still lurking somewhere deep down in my computer and doing nasty things?
(I am reluctant to install an antivirus, because it sometimes uninstalls many Chrome extensions I installed manually (from crx files). Also, they tend to make many other programs dysfunctional as well.)
Thank you very much for taking your valuable time to read such a long post.
