Virus

My internet explorer seems to be bogging down lately when I have a few browsers open. When it gets real bad I run my security scan and eliminate anything that could be slowing down the process. Almost every time,my computer returns to normal speed and all is well... at least for a little while. Try running a virus scan, if you have one. If not, I recommend that you look to invest in one.

I think u should use good antivirus.I think AVG will help u to solve this
