I was looking through the coding for a .pif virus that came in email and winnet.dll is one of the files it calls.
you cant open internet explorer without it
My Antivirus found it as infected and took it to the virus vault (AVG) , because it couldn't heal it! And then some of my programs couldn't start (Scype,Yahoo Messenger,Download Master,Internet Explorer and other)
ewido will erase this problem

Aufpassen beim Dateinamen!
a very common piece of spyware..usually comes bundled with game software but is in other software as well
It runs some standerd internet connection that is linked to IE browsers. It's a favorite target for viruses and spyware cause it's the 1st file that it goes though. I lost mine cause my AVG anti-virus system killed a virus but also killed my WININET.dll file cause it was "infected". I'm looking for a way to reinstall the file, but for now I suffer. T_T

Best practices for resolving winnet issues

The following programs have also been shown useful for a deeper analysis: Security Task Manager examines the active winnet process on your computer and clearly tells you what it is doing. Malwarebytes' well-known anti-malware tool tells you if the winnet.dll on your computer displays annoying ads, slowing it down. This type of unwanted adware program is not considered by some antivirus software to be a virus and is therefore not marked for cleanup.

A clean and tidy computer is the key requirement for avoiding PC trouble. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
