Sophos Antivirus on Windows 7 RC (Build 7100)

As you may be aware, Windows 7 has a number of beta products and applications that you can download to help protect your Windows 7 RC system.

Dwight Silverman: Getting the Windows 7 RC? You’ll need protection

Sophos is our corporate AV supplier, so it was important that I maintain similar protection on my Windows 7 RC laptop system.

Sophos is not listed amongst the Windows 7 antivirus partners, however, I can happily report that Sophos 7.6.7 (designed for Vista) works great for me on my x86 version of Windows 7 RC. It also worked great on a Virtual Machine running the x64 version of Windows 7 Beta. Pictures shown here are from the x86 version of Windows 7 running on a mid spec laptop.

As you can see in Figure 3, the only snag with running this in Windows 7 is that is doesn’t report its status in the correct format, however, I’m watching the space for a new version of Sophos to be fully functional very soon.

Figure 4 shows that whilst Windows 7 acknowledges the fact that Sophos does not report status correctly to it, the application itself is fully functioning.

I know some of you reading this will be asking why I don’t simply pick a free alternative, such as Avast! or AVG… I have considered going that way, but Sophos works great, and why fix it if it doesn’t seem to be broken!

I do hope the lab team at Sophos fix that status issue very soon, as it is the only minor flaw.

I cannot give enough superlatives for this new operating system, it is the most stable RC I’ve ever had the pleasure to use, and works a treat on my mid spec laptop (new in 2005).


P.S. please let me know if you are successfully using Sophos on Windows 7 RC :-)

    I’ve actually noticed it is much more CPU intensive than it was with even the beta. There’s something in the realtime scan that needs to be tweaked. Doesn’t kill the machine, but there are times when I have definitely noticed a lag.

    I am testing Windows 7 RC 7100, As Soon as I installed sophos 7.6 (updated to 7.6.8) it prevents IE 8 from starting correctly upon looking at my sophos log, I found out the scanner keeps trying to scan ieapfltr.dat every second I TRY to launch IE 8, I know this is sophos, because I completely reinstalled the OS and it started again after installing Sophos. I have added the file the authorized list for suspicious files etc. However it still takes anywhere from 2 - 12 clicks for IE8 to launch, What is going on ? By the way I am using Sophos Firewall as my Kerio Winroute prevent me accessing everything but IE8, What is the deal with Windows 7 and IE8?

    I have had the same problem with IE8 (x86 and x64 versions) and Sophos. Open the Internet Options Control Panel, then go to the Advanced tab, and finally click on Reset. You can choose to delete personal settings if you wish. This should take care of the issue. This will disable all add-ons. You should now be able to open IE, and re-enable all add-ons except for the Sophos one, though I re-enabled it and it seems fine now.

    Each time i install and use Sophos in Win 7 any application I try and use the pc immediately crashes. It workd well on my XP and Vista laptops but is disastrous on my brand new desktop.
    I have tried several different attempts at making it (newly d/l endpoint8 for win7 ) work but each time I attempt to use any appliation the computer stops and then on restart wants to carry out a repair, but fails to succeed. Any help in this would be greatly appreciated.
