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.

You may have installed the Yahoo Toolbar without knowing it or accidentially changed your startup page without realizing it.

Many toolbars, Add-ons, screensavers, and weather monitoring programs come bundled with other software (often without the knowledge of the user) and can be the source of various issues and problems to include Adware/browser hijacking. Even if advised of a toolbar or Add-on, many folks do not know that it is optional and NOT necessary to install in order to operate the program. Toolbars and Add-ons can usually be removed via Add/Remove Programs or the Programs and Features in Vista/Windows 7/8, so always check there first.

If the program is not listed in Add/Remove or Programs and Features, the next place to check is your browser Add-ons.
