Good afternoon everyone, A short time ago, a Sirefef Trojan was detected during an SAS quick scan on my computer. Somehow, the C:\WINDOWS\SYSTEM 32\DRIVERS\ipsec.sys file was deleted (either by the trojan itself or during the removal from quarantine process I did with SAS). I subsequently had no Internet access and spent $123 to get my computer back up and running. My question: Is there a way to COPY the ipsec.sys file to a USB flash drive and re-install the file if a similar adverse event should occur in the future? (I do not have a 2nd computer to use either). Thank you for your time and any information!
