Nav virus

The Nav virus, or Nav.exe virus, is a backdoor Trojan that's installed by the RBOT-IV worm and is typically the first thing that an RBOT-IV worm installs on any PC that Nav virus infects. This is accomplished through an Internet Relay Chat or IRC-based backdoor that allows a remote criminal to upload the file to your computer via an IRC server, while ignoring your firewall and other network security programs. Because Nav.exe virus's primary function is to install other forms of malicious software and conceal Nav virus' true nature, there may be few signs of a Nav virus infection on your PC, other than some suspiciously-altered system settings and unusual memory usage. You should use a competent anti-malware program to detect and delete Nav virus and any related infections, such as RBOT-IV worms. SpywareRemove.com malware researchers recommend that you do this as soon as possible, once you suspect a Nav virus infection, since Nav virus and RBOT-IV are both capable of installing high-level PC threats, including rogue security programs, keyloggers and RATs.

Keeping the Nav virus and Its Self-Duplicating Comrades Out of Your PC

Nav virus infections are almost always accompanied by RBOT-IV worm infection, with the two programs working hand-in-hand to create vulnerabilities on your PC to install other PC threats. You may be able to notice the presence of one or both of these infections by noting firewall or network settings that have been changed to allow the Nav virus and related infections to be installed. Detecting Nav virus's memory processes, NAV.exe, in Windows Task Manager is also possible, although a Nav virus may try to pretend to be a normal system process.

SpywareRemove.com malware experts also note that Nav virus, despite Nav virus' name, isn't related to Norton Antivirus (a legitimate PC security brand that often uses NAV as an abbreviation for its software). Nav virus has also been known to masquerade in the form of a fake Windows update; if you have trouble differentiating between a legitimate program and a Nav virus, you should use an up-to-date anti-malware program to do the detective work for you.

Since the Nav.exe virus's RBOT-IV worms (also known as W32/Sdbot.worm.gen.w worms) can infect new computers over local networks and through portable storage drives, you should be especially careful to avoid spreading a RBOT-IV infection through this means. Standard Autorun-based vulnerabilities will allow RBOT-IV worms and Nav.exe viruses to infect new computers without consent or even visible signs of this activity when it's happening.

Counting Out the Nav.exe Virus's Potential Cohorts

Most Windows PCs are vulnerable to Nav.exe Virus attacks, which may install some or all of the following types of malicious software:

• Remote Administration Tools that let criminals use your PC for DDoS crimes or spambot attacks.
• Keyloggers and other forms of spyware that record private information, such as account passwords, and send that data back to criminals so that it can be used for fraud and account break-ins.
• Rogue programs that pretend to be anti-virus scanners, anti-spyware products or file cleaners. These programs can interfere with your PC and create inaccurate warning messages, but their primary goal is to steal money via fraudulent software registration processes.

Nav.exe virus and RBOT-IV worms are especially noted for being affiliated with spyware and spambots, but may also install other forms of harmful software. Since the Nav Viruses has been known to use fake Microsoft update pop-ups to install Nav.exe virus' payload, you should be especially watchful against unusual or suspicious Windows update alerts.
