Id say its kind of like having a self inflicted gaping wound before you've figured out how your going to treat it.Spencer, I read this article about 24 hours ago and was disappointed that there was only one option. Now that most of the major vendors have SP AV products, has anyone done an indepth review of them?

What I noticed recently was that this didnt fix the problem at all, it generally made a bit more of a mess.

So, if you find that the Cache folder has an update in there (Usually 68Mb ) Navigate to: C:\Program Files\Sophos\Auto Update\cache\savxp and click Install Sophos Anti Virus, this will run you through a quick Win Installer and then update the program.

And now today, on a whim, I checked back to make sure the link I put in my reference document is functional and you've gone ahead and updated the whole thing. I'm just at the budgeting stage, but don't want to end up with a lemon just because it's cheaper...

Thank you for being on top of this and taking the time to keep the information accurate.

It's fair to suggest that Windows 10's built-in antivirus solution, Windows Defender, is the last free AV app you should trust to keep your system clean.

Not that it's overtly bad – although it does tail behind just about every third-party antivirus solution – but because it has a big target painted on it for attackers.

If you happen to work for those companies and have news for me, please get in touch and I can update this page (which I will review and update once a month). I know some of these vendors have a hard time selling AV for Share Point because they view it simply as a document repository.

Documents can of course contain malware but it's just not the most common vector. Yes we (Trend Micro) are later on supporting Share Point 2013 than we would like.

I found quite a neat little trick, whether or not the following technical processes are by design I dont know but I assure you this has worked for me loads of times.

Those locations are: C:\Program Files (x86)\Sophos\Auto Update -or- C:\Program Data\Sophos\Auto1If I restart the PC with this problem and boot into Safe Mode, log in then out, the bad file is automatically deleted, restart into normal Windows and try the install again.
