I am running Windows Vista on a laptop, but then I noticed that peerguardian had started blocking something before I opened up any kind of p2p program or internet browser. It is blocking something called "ZlKon Exploits" constantly. I googled this and eventually made it another post that suggested first running super-antispyware, next running malwarebytes anti malware, then combofix, and one other. I read on your site not to run combofix without guidance, but I did try to run both the first two programs. Super-Anti only asked for UAC permission and then that "stopped working" box came up. Next, the malwarebytes seemed to install but when I click "Finish" with "Start" and "Update" checked it simply does nothing. I go to a school, and we're required to run one of the worse McAfee version I've ever seen, so I only expect problems with subsequent scans. Hmm... I also have two external hard drives that I can use to back up all of my data, but my concern is of course saving the infection, and I would appreciate some guidance here. Thank you so much! I hope to hear from you soon. Ciao for now.
