I've now gotten the Internet Security 2013 virus twice. It was MrSEC.com both times, by the way, and even if I try to avoid the site, a lot of reputable sports sites link there. The last one was on a link off the USA Today sports home page!
I have my home computer locked down with Spyware Blaster and scan with Malware Bytes and I know I've been to MrSEC.com accidently since they've been infected without any problem. So something that I have configured at home (probably by Spyware Blaster) blocks it.
The problem I have is that my company doesn't give me admin rights or let me install software so I can't run Spyware Blaster on my work computer. Yes, coming in through a basic user account, the Trojan rogue can break things, but the internet settings are locked such that I can't get in to block it.
I was wondering if anyone knew what setting Spyware Blaster changes to block it because I could temporarily request an "admin login" that would let me change them but not install a SW package.
