TROJ_AGENT.BCPC is a Trojan downloader that installs adware (software that floods your PC with pop-up advertisements) without your consent. Because TROJ_AGENT.BCPC places some of its files in the default folder for your printer's spool, you may also experience your printer printing out long pages of gibberish; this symptom is also characteristic of similar PC threats like Trojan.Milicenso and TROJ_PONMOCOP. For the sake of your computer and your (undoubtedly expensive) printer cartridges, SpywareRemove.com malware experts recommend that you find and delete TROJ_AGENT.BCPC with anti-malware scans from suitable security programs. These scans should also be sufficiently thorough that they can catch TROJ_AGENT.BCPC's payload, which may be reconfigured to include other PC threats besides adware.

How TROJ_AGENT.BCPC Slunk Over to Your Printer

At the time of this writing, TROJ_AGENT.BCPC's infection vectors are all various forms of malicious sites, including forums and sites that exploit Google search algorithms to inflate their ranking. SpywareRemove.com malware researchers recommend that you be particularly cautious when downloading archive files like .zip, which is one of TROJ_AGENT.BCPC's preferred file types. A manual download may not always be necessary; drive-by-download exploits may also install TROJ_AGENT.BCPC without your permission.

There are only two traits that are associated with TROJ_AGENT.BCPC's attacks as symptomatic of its presence, although these characteristics are highly-visible:

  • Random characters printing from your printer, seemingly indefinitely. This is caused by files that TROJ_AGENT.BCPC or its payload, ADW_EOREZO, has placed in your printer's spool folder; the resulting code is printed out by your printer automatically. Removing the files will allow your printer to behave normally once again. Shutting off your printer until TROJ_AGENT.BCPC is deleted is a recommended bandaid fix to prevent you from wasting excessive paper and ink.
  • Pop-up advertisements, potentially with malicious content, that are displayed by ADW_EOREZO. ADW_EOREZO is installed automatically by TROJ_AGENT.BCPC and will launch itself without your consent. However, TROJ_AGENT.BCPC may be reconfigured to include other PC threats for installation in the future.

Firing This Agent of Paper Waste

As a mid-level PC threat that installs other forms of hostile software, TROJ_AGENT.BCPC should be removed via anti-malware scans that can also delete any other software, like ADW_EOREZO, that TROJ_AGENT.BCPC has installed. Assuming that TROJ_AGENT.BCPC is removed properly, there shouldn't be any risk of permanent damage to your computer, including your printer. Operating systems that are vulnerable to infection by TROJ_AGENT.BCPC include Windows 2K, Windows Server 2003 and Windows XP.

Having good browser security settings is encouraged by SpywareRemove.com malware analysts as one way to prevent your PC from being infected by TROJ_AGENT.BCPC. This includes scanning files before you download them, disabling exploitable features (like Flash and Java) for suspicious sites and taking care to acquire software updates only from reliable sources.
