Безопасен ли mediafire.com?

For some reason, I keep getting a malicious pop-up that tries to download iLivid every time I click on the download button. The pop-up somehow manages to bypass AdBlock, which is a real pain in the neck. I scanned my computer with Avira, Bitdefender, and Qihoo 360, and none of them detected anything. Sometimes it even gets to the point where new tabs open right after I click the download button, and most of the websites I am directed to all have red WOT ratings.

site is useful, i use it as a last resort backup, but download links are pepperred with spam. the spam in question appears to contain some driveby virus pages. really mediafire behavs like 2 different sites, one legitimate and clean in interface design when one is uploading and one coverd in spam and filled with pop ups when one downloads files from it.

The site itself is amazing, but I would not trust ANYTHING on here, if your life depended on it. The pop-ups are INSANE, and I have actually received a "Worm" and several "Trojans" as courtesy of shifty people bombing download links. Watch yourself, and make sure you have every form of Ad Block/Ad Block Plus for Firefox, and Malwarebytes for your computer if using Internet Explorer before coming ANYWHERE NEAR THIS SITE. Trust me, it'll save you a hard drive or three. :/
