I have been using the free version of Ewido for months. I also have subscriptions to McAFee VirusScan and Webroot Spysweeper. Suddenly, tonight, McAFee detected an alledged Trojan: New Malware.z in the Ewido program files: guard.sys. I need to know if guard.sys is a normal program file for Ewido. If it is, is there any possibility that it could become contaminated bya trojan? After Mcafee detected this, I quanrantined the file and then uninstalled Ewido, deleted all other Ewido files I could find, ran CCleaner, and then downloaded a fresh install of Ewido. McAFee found the alledged trojan again. I sent the guard.sys file to Virus Total, and none of the other scanners dectected any trojan. Does anyone know if this is a new incompatibility between Ewido and McAFee? I am hoping that this is just a false positive for McAFee, but I worry that I might miss a real threat if I just ignore it. Anyone else have this issue come up? I cannot find any info about New Malware.z in the McAfee knowledge base.
