A friend of mine used my pc and now CWS is on my system. I bought Spy Sweeper and found two installed cws programs on my system. I removed them with spy sweeper but instantaneously showed back up. So i treid it in safe mode, found the same two "things" on my system but could not get rid of them. Very hard to surf the web. So I read the Mozilla's Firefox was a good browser for this kinda stuff. Well I installed it and it works great. My question to you is how do I get it off my system? Does this attach itself to files. Do I have to format my harddrive?
