Title says it all. If I go to the thread for LCPDFR:

The download is listed as suspicious by your own site. I click to find out more and more than half the files appear to be infected, click to see the results on the virustotal page and it says it is filled with trojans, adware and other malware...

Have you guys been hacked...? There's no way it's ALL false positives...

LCPDFR utilizes significant memory resources to achieve its functionality. It's important to note that even popular anti-virus software, such as McAfee, can produce numerous false positives.

Most antivirus software does NOT like it when anything injects itself into another .exe, which is what LCPDFR and LSPDFR do to function, so that is why they both are sometimes detected as a virus. More specifically ragepluginhook is affected by this but it can also happen to .dlls like lcpdfr and lspdfr
