Thank you in advance to anyone who is willing and able to guide me through a possible virus. As the title states, my computer has begun acting strangely and I fear it is infected.
Normally, my start up page is Google, when I use my Chrome browser, however, after searching and downloading a movie, things began to get weird. My computer is acting generally slow, and suddenly my start up browser has changed to Yahoo. I fear these are signs of a virus and I would like to take care of this situation before things get worse.
I am fairly inexperienced with virus removal, and I am not sure how to best approach such a vague situation. I ran a Trend Micro Titanium internet Security, but no threats appeared. I would like to go for a general thorough examination of my computer.
I am using a Windows 8 Operating system.
Thank you again.
