How Did You Get Worm.Chernobyl6.a?
Wondering how Worm.Chernobyl6.a ended up on your PC? If you’re infected with Worm.Chernobyl6.a or other badware, perhaps you were using…
- Freeware or shareware: Did you download and install shareware or freeware? These low-cost or free software applications may come bundled with spyware, adware, or programs like Worm.Chernobyl6.a. Sometimes adware is attached to the free software to “pay” developers for the cost of creating the software, and more often spyware is secretly attached to free software to harm your computer and steal your personal and financial information.
- Peer-to-peer software: Do you use a peer-to-peer (P2P) program or other application with a shared network? When you use these applications, you put your system at risk for unknowingly downloading an infected file, including applications like Worm.Chernobyl6.a.

I recommend you use Firefox web browser, if you don’t already.
Understanding Worm.Chernobyl6.a
If you’re infected with Worm.Chernobyl6.a, you should know what you’re fighting. I’ll explain some definitions related to Worm.Chernobyl6.a.
Worm.Chernobyl6.a May Be Rogue Anti-Spyware
Rogue anti-spyware refers to anti-spyware/antivirus software of questionable value. Rogue anti-spyware may not be proven to protect your computer from spyware, may popup fake alerts or create many false positives about your PC being infected, or may use scare tactics to try to get you to purchase the application. Rogue anti-spyware software may be installed by a Trojan, come bundled with other software, or install itself through web browser security holes. While it is fairly rare, some rogue anti-spyware is created and distributed by known spyware or adware companies, and the rogue anti-spyware may install spyware or adware itself.
Often when you’re infected with rogue anti-spyware like Worm.Chernobyl6.a, you’ll see a false popup security alert like this:

Rogue Anti-Spyware Tactics
Typically, rogue anti-spyware such as Worm.Chernobyl6.a has one or more of the qualities listed below, which is why rogue anti-spyware is considered anti-spyware software of questionable value.
- False positives/fake alerts: Rogue anti-spyware may produce a large number of false positives or use fake alerts, noting that your computer is infected with spyware parasites or other threats that do not really exist.
- Copycat looks: Rogue anti-spyware may copy the look and feel of other legitimate or rogue anti-spyware applications. Often, rogue anti-spyware applications may appear as close clones of other rogue anti-spyware software.
- High pressure marketing: Rogue anti-spyware may use scare tactics or other aggressive advertising and marketing tactics to try to trick you into buying the rogue anti-spyware application. Often, rogue anti-spyware may produce false positives and fake alerts about your computer being infected.
- Poor detection/scan reporting: Rogue anti-spyware may produce poor reports when it scans your PC. For example, rogue anti-spyware may say your computer is infected 11 parasites, but not specify which spyware parasites or what type of parasites. Rogue anti-spyware may also report that your PC is infected with SafeAndClean, but not tell you which related files, DLLS, etc. were found on your computer.
- Weak scanning/detection: Rogue anti-spyware may not only poorly report on computer infection, but rogue antispyware may also poorly scan your PC. Rogue anti-spyware may skip over important folders and files of your computer that should be scanned to detect spyware.
Did Worm.Chernobyl6.a use these tactics to trick you into buying Worm.Chernobyl6.a?
Worm.Chernobyl6.a May Be a Worm
Worms are virus-like badware with destructive codes. Worms are able to mutate, or replace their own code by automatically, which makes worms very dangerous, difficult to find, and hard to delete. Similar to viruses, worms can spread to the other computers by secretly and automatically emailing themselves to other Internet users in your address book. The main difference between worms and viruses is that a worm wil replace your computer files rather than simply inserting their code into your files.
