What's wrong with my phones' internet?

[FranklinRose]

So in the past few days, my internet has been acting wierd. My webpages takes minutes to load and i'm not on advanced websites, just the mobile versions of it. The Google Play store takes forever to load. Instagram, twitter, facebook, and youtube take forever to load and buffer.

My friend told me that i might have a virus. She then told me that i would have to delete the task manager to make my phone run better.

I'm pretty sure that i do not have a virus, and that I actually need the task manager. Any help?

I have a T Mobile Samsung Exhibit 2 running android 2.3.6. I used the dolphin browser since June and uninstalled it this to be my friend said that it is the reason for my problems and to go back to the default browser, a choice i did not want to make.

Ps, I also understand that there is no such thing a program that CANNOT get a virus and i understand that programs have viruses because more people own that program, so more people can "tinker" with it.

Get your phone Scanned by a good antivirus it may have been infected by some spyware
or "factory" reset your phone
the process depends on your phone model
