I went to the Encyclopedia Dramatica page for Albert Einstein today, and once the page had loaded, my antivirus software told me it had found
in my system and would I like to clean it out? I told the software to do so, and it reported that all was now well.
Googling pdfjsc.H turns up nothing useful–just two uninformative hits where the file turns up in a list of files on someone’s system. I wonder if anyone here knows what it is. Did I come near disaster? Without antivirus software, would my laptop have started smoking or something?
Googling the second name gives this, which suggests that it is a file trying to exploit the vulnerability in Adobe Acrobat mentioned here (which contains links to upgrades containing security updates).
“xcvb.pdf”. The “[1]” usually just indicates that there was already a copy of that file there when some process tried to create another. Check the MD5 hash, though; that’s your best guide to whether it’s the same file or not. (Or, as a lazy man’s way out, just check the filesize, I suppose…)
Hmm… That scares me a bit, since the antivius program only found xcvb[1].pdf. This makes me wonder if there’s still a copy of xcvb.pdf lurking. I’ll have to check tomorrow when I get back to that computer.
