TomHD Posted February 2, 2015 Posted February 2, 2015 Hello All, Last week we were placed on a blocklist The CBL I unblocked us but we were soon blocked again! Virus or malware! I have installed the latest SEPM and deployed the clients across the network. I left it to run over the weekend and it found some Trojans. According to the blocklist page, the problem was last detected over 2 days ago. Can I assume that the problem has been removed? And would this mean I am safe to unblock us? Many thanks, TomHD.
jjohnsoncantell Posted February 19, 2015 Posted February 19, 2015 we were on this list also recently. If you're confident you've cleared the infection then you can request to unblock yourself. I did this yet we had the same trojan bought back in on a laptop that was being used at home so we were blocked again. Make 100% sure you're clear before unblocking. Check your ip on this site too IP Address Lookup as the chances are you may be blocked on some of those too.
RobD Posted February 19, 2015 Posted February 19, 2015 We had a similar issue, the best thing we did was block port 25 on traffic out of our firewall on every IP except our Exchange servers.
