Question:I found a process named 4u.exe running on my computer. Should I worry about it?
Answer:Yes you should! 4u.exe is a backdoor program that allows an attacker to remotely access and control your computer.
You probably got this program from some other infected computer via email. You should delete it as soon as possible.
If you saved passwords (in ANY form!) on your computer consider them known by someone else. So after removing 4u.exe you should change all those passwords.
