HEUR_PDFEXP.E Description

HEUR_PDFEXP.E is a general identifier for PC threats that disguise themselves in the form of PDFs to exploit JavaScript-based vulnerabilities and install malicious software onto your PC. Although SpywareRemove.com malware experts are still analyzing HEUR_PDFEXP.E's current payloads, HEUR_PDFEXP.E attacks have been found to originate from PDFs that are named to reference recent US political events such as the presidential campaign between President Obama and challenger Mitt Romney. Accordingly, since that informative document may very well be HEUR_PDFEXP.E or a similar PC threat in disguise, a high level of paranoia is recommended whenever you're using general web searches to find political information.

HEUR_PDFEXP.E: Just One of Many New PDFs That Hope to Turn Your PC into a Warzone

HEUR_PDFEXP.E is an example of criminals using current events as marketing tools for their own malware. Recent investigations into exploitation of common keywords related to the US presidential elections (such as 'Obama,' 'Romney' or 'election') have uncovered a multitude of malicious websites that present themselves as political news sources while displaying hostile or irrelevant content. In some cases, as many as one out of every five of these malicious URLs were guilty of being mere spam, but the vast bulk of such websites were used for malicious software-related attacks like HEUR_PDFEXP.E.

These websites host HEUR_PDFEXP.E and similar PC threats (HEUR_PDFEXP.C, HEUR_PDFEXP.A, HEUR_PDFEXP.B, etc.) with file names that reference tax policy contrasts and other political news relevant to the US presidential elections. However, anyone who tries to open these PDF documents will be attacked by embedded JavaScript exploits that install hostile software. To protect your PC from HEUR_PDFEXP.E and related dangers, SpywareRemove.com malware researchers encourage you to avoid downloads from sites that aren't trustworthy and scan files with anti-malware software prior to opening them.

Why US Political Antics are a Concern for the World at Large

Interestingly enough, while HEUR_PDFEXP.E and related attacks are (as expected) mostly racking up victims in the United States, residents of other countries have also been victimized by these attacks. SpywareRemove.com malware research team has noted a minority of victims in Australia, Japan, the UK, Canada and even Poland. Overall, while HEUR_PDFEXP.E and other corrupt PDFs are a major factor in this malware-based exploitation of politics, attacks that use identical social engineering tricks include a colorful range of adware, worms and Trojans.

As is often relevant, scanning any files before you download or open them should be considered an excellent defense against HEUR_PDFEXP.E and its fellows. If you've launched HEUR_PDFEXP.E or another type of malicious file due to these misleading circumstances, SpywareRemove.com malware researchers only can suggest that you use anti-malware products to disinfect your PC and get rid of both HEUR_PDFEXP.E and the other software that HEUR_PDFEXP.E is certain to have installed.
