My computer got rebooted like 4 times already?

This is getting on my nerves, within a week, my computer has had to be rebooted about 4 times due to viruses. It all started when i searched something for my game on google, then everythime i searched something, it would redirect me to another search engine. i caught something in the link that it redirected me to as "Find-quick-results" or something. anyways, since then, my computer would get a virus. the next day, i would reboot my computer, but the virus would come back... This is seriously getting on my nerves. please help?
