This is a topic for development of ways to defeat the dreaded Google Redirect Virus, a powerful Virus that can bypass security tools and disable firewalls. It infects the core system, so all browsers are affected. I know this is a little off topic, but if you're googling to get some stuff for a scratch project (like sprites) or finding a forum topic easy, you'll really be annoyed. Also note you can possibly receive this from innocent sites, possibly even scratch or minecraft.net, so go warned.
Symptoms:
- Your browser slows to a crawl (Most obvious when typing)
- You go to shady sites when you search, such as happilli or added success, though the sites vary by user and by version of the virus
- Your desktop is changed randomly, possibly to something disturbing, scary or inappropriate for scratch
- You're blocked from accessing sites you like
- You get weird errors that are false (such as errors relating to files that have nothing to do with your browser)
There are likely more, but these are the ones I've seen and have happened to me.
A way to partially disable the virus is by frequently changing search engines, which confuses it and may stop it from properly functioning. Doing 5 searches a day on a search engine you don't normally use works for me.

Usually, MalwareBytes can get rid of viruses other anti-viruses can't get.

That's shown to be the most effective. Though tricking the virus is possible, it takes 5-10 minutes of work to trick it into deactivation so you can search freely well it's on your computer. Some data I've found shows it may infect your router, not your computer.
