Computer Worm Infections
NetProAZ specializes in the detection, removal of and protection against worm computer infections. Worm infection removal is included in our virus removal package and our pc optimization package (recommended). We also offer DIY downloads for removing your own worm infections as well.
Worm Computer Infections
This variant is a self-replicating and expanding application. Very well known for it's ability to spread via nodes or weak network security structures. Typically worms do not alter or disrupt as they pass, but the more recent, re-written versions do just this.
Worms that are not simply 'passing through' a computer, or typically a network, are carrying code that is referred to as a 'payload'. A payload is exactly what one might guess; It has a package to deliver or task to accomplish. The two most common payload worm types we have personally seen are relatively smile variations that, via multiple formats, create alternate identities or utilize the host's own identity, and replicate themselves' by publishing to your entire contact list, and the second is a more involved backdoor hidden user concept that is becoming more rare as time passes and security measures increase.
We have seen more worms in office network environments than home or desktop machines over the years; Typically causing more disruption than damage in most cases. Either way, it's a malicious application.
Worms typically enter through exploits in operating systems, outdated or end-of-life applications, bundles, previously created back doors, email replication, and the most common we see currently is, outdated IM and similar communication software exploits.
Keeping your entire computer and network up-to-date and current lowers the % of malicious application entry to nearly null, excluding current exploit attacks and accidental email or bundled release, of course.
In addition, paying attention to what you are doing and being realistically cautious always helps in every situation. Don't open emails and attachments from senders you don't know or 'OK' scripts or downloads that you didn't initiate or download recklessly in questionable environments, specifically file sharing sites and peer-to-peer networks. Being careful, paying attention and thinking before you click goes a long way towards ensuring your system's security and integrity.
" The key to worm avoidance is properly established networks, administrative boundaries and email identity and user account security structure, accompanied by a fully updated and patched system, including all software and helper applications. "

Other Computer Infection Types
Adware
This is a type of software or application that typically plays, displays, monitors or pops-up items that would be ethically defined as “above and beyond acceptable advertising or monitoring methods or practices.”
Malware
Is basically short for malicious software and includes all categories or sub-categories of software or applications that quite simply have a negative intention or deceptive/destructive outcome.
Spyware
This software or application obtains information from a user's system or network without that user's knowledge or consent.
Rogue
This application type typically poses as a valid piece of protection software that generates pop-ups and fake errors / scans / reports that are designed to fool and scare the end user into downloading a desired piece of software. These are the most common any annoying of the bunch and probably have the highest rate of success, monetarily speaking.
Trojan
This term is derived from the trojan horse story in Greek mythology and it's purpose and intention is just that. Not only does a trojan install itself in an isolated location, but it typically generates multiple, executable locations and registry entries as well. These trojans are typically referred to as hoppers or downloaders. Either way, a trojan's goal is always the same, with some coded variation and technique differences only. That goal is to allow access to your system or network so that a user or other malicious software/application(s) may now enter at will.
Replicant
This is one of the hardest variations or infection strains to remove and requires the exact steps be taken, in order, and the correct tools be utilized to even have a chance at removal. These variants typically begin with the prefix win32* and replicate at an uncontrollable rate by infecting all .exe and system files as they are utilized by any user or system privilege level.
Root Kit
These applications are also extremely hard to remove in most cases and typically require advanced knowledge of system structure and usage as manual steps are often required to remove specific elements of the architecture. Root kits are most commonly bundled with another application that requires your 'approval' to install. By utilizing this methodology, they are much harder to detect and have a much more diverse range of control and damage potentials. They are also self concealing, or completely stealth in nature, often utilizing multiple points of control, entry or user and privilege manipulation.
Hijacker
This software application typically takes control of your primary browsing interface, system desktop or both. This a a very noticeable and bothersome infection type that involves popups, redirects and similar or structural and esthetic changes to your desktop layout that cater to the infection's intentions.
Pop-Up
I think everyone has experience a pop-up at one time or another. This is one of the oldest, and yet still utilized, application types. Pop-ups are often released while you are browsing and typically timed or have a release methodology. The more recent versions of this infection type involve connection and disturbances even while you are not actively using a browser and have basically evolved into the rogue classification due to it's continued rate of success.
Riskware
Riskware is a broad category that most potential or would-be threats are thrown into, to put it quite simply. This also parallels or includes popular industry acronyms such as; PUA, PUP, etc. Sometimes this reference or database category is utilized when a protection software locates a coding pattern that seems malicious or follows another variation's structure but it hasn't been assigned as a threat just yet.
