Is it possible?Or do you know of other ways on how I can remove it. I think the connection has been slowed down. Yesterday, when I download it has 80-100 kbps rate but now its only on 40-50kbps. What do I do with it.
Before reinstalling, I'd try one or more of the free spyware removal programs. I'm particularly fond of Spybot Search and Destroy which is a very well known and highly regarded free adware/spyware removal program.
I've also had good luck with the free version of Lavasoft Ad-Aware in the past.
It's important to stick with adware/spyware removal programs that are well established and have a good reputation because occasionally spyware/adware comes disguised as a removal program or a "system cleaner". A lot of these turn out to be just advertisements trying to sell you a sub-par product.
Hijackthis is another free product that can help but it takes a little more care to use. It can make things worse if used to aggressively.
The only sure way to get rid of virus/malware is to reinstall the operating system.
Don't count on being able to do it manually. And it may take longer than reinstalling.
In addition to anti-virus/reinstalling the OS, you may want to test your connection on another computer.
I've had my actual connection slow down a few times; I ended up having to call the ISP to get it fixed.
