Win32.Enistery is a generic identification for unspecified malware threats. In many cases, Win32.Enistery has been reported to be a false positive from harmless temporary files and not a true infection. Deleting Win32.Enistery is unlikely to harm your system and may help it, but this threat identification will usually come back after being deleted. It's recommended that you use multiple anti-malware scanners to try to detect the Win32.Enistery infection, and use the scan results along with evidence of malware symptoms to decide whether or not a serious anti-malware solution is necessary.
Win32.Enistery Can Be the Potential Threat – Or Not!
Since mid-2010, the most common occurrence of Win32.Enistery has been through temporary files created by various legitimate anti-malware scanning products. These products will sometimes leave behind small files as traces of their scanning work; such files are almost always deleted automatically after a reasonable period of time. You will not ordinarily see temporary files without altering your hidden files settings, and these files will usually be left in cluttered locations that make finding them tedious work even if you can see them.
Genuine anti-malware products don't use temporary files for malicious purposes, but these files may still show up as Win32.Enistery infections. If you trust your scanning products and are sure there aren't any other complicating factors involved, then it's usually safe to ignore the Win32.Enistery infection.
Don't Let Your Guard Down Just Yet
In some cases, Win32.Enistery may represent an actual threat that hasn't been fully identified. If you notice unusual system behavior symptomatic of malware infections, or see multiple legitimate scanning programs providing Win32.Enistery infection results, the infection may be true malware.
Removing Win32.Enistery has so far been indicated as a difficult task in most cases; you should rely on Safe Mode and thoroughly updated anti-virus scanning products to do the job for you rather than attempting it on your own. After each deletion attempt, reboot your computer and repeat the scans – if you see the Win32.Enistery infection appears again then Win32.Enistery was never fully deleted in the first place.
Given the broad nature of this infection identification, even reliable application may fail at deleting Win32.Enistery. If this is the case for you, you may want to consider getting more specific help from technical forums and customer service professionals that should be able to offer solutions to your Win32.Enistery problem that are tailored to your situation.
