Overl Categorized as:
Worm
Worms are generally considered to be a subset of viruses, but have key differences. Unlike a virus, a worm is a computer program that replicates, but does not infect other files. Instead, a worm installs itself on a computer and then looks for a way to spread to other computers.
From a user’s perspective, there are noticeable differences. The longer a virus goes undetected, the more files it will infect on the victim computer. By contrast, there is just a single instance of the worm code on the computer.
Like viruses, worms are often subdivided according to the methods they use to infect a system. E-mail worms are distributed as attachments to e-mail messages. IM worms are attached to messages sent with instant messaging programs (such as IRC or ICQ). P2P (peer-to-peer) worms use file-sharing networks to spread. Network worms spread directly over the LAN (Local Area Network) or across the Internet, often exploiting a specific vulnerability.
DoS
A DoS (Denial of Service) attack is designed to disrupt or stop the normal running of a Web site, server, or other network resource. Hackers or malware writers resort to various ways to achieve this. A DoS attack can commonly result in a server being flooded with more network traffic than it is capable of processing. This hinders or prevents the server’s normal operation and sometimes causes its complete failure.
Unlike a DoS attack, a DDoS attack employs multiple PCs. The hacker or malware writer normally uses one infected computer - “master” - to centrally coordinate the attack across other, so-called “zombie”, computers. Typically, the malware writer gains control of both master and zombie computers by exploiting a weakness in an application or the operating system on those computers, in order to install a trojan or other malicious code.
How Did My PC Get Infected with Overl?
The following are the most likely reasons why your computer got infected with Overl:
- Your operating system and Web browser's security settings are too lax.
- You are not following safe Internet surfing and PC practices.
Downloading and Installing Freeware or Shareware
Small-charge or free software applications may come bundled with spyware, adware, or programs like Overl. Sometimes adware is attached to free software to enable the developers to cover the overhead involved in created the software. Spyware frequently piggybacks on free software into your computer to damage it and steal valuable private information.
Using Peer-to-Peer Software
The use of peer-to-peer (P2P) programs or other applications using a shared network exposes your system to the risk of unwittingly downloading infected files, including malicious programs like Overl.
Visiting Questionable Web Sites
When you visit sites with dubious or objectionable content, trojans-including Overl-, spyware, and adware, may well be automatically downloaded and installed onto your computer.
