I am a ESET Nod32 Antivirus user. Please note that although I refer to ESET Smart Security below, the software I am using is ESET Nod32 Antivirus. Since buying a new computer (with Windows 7 as the OS) last week, I have been having problems uploading large files to various web sites, such as Box.net, Dropbox.com, etc... (I use these sites to share files with clients). The files appear to upload instantly (the upload meter shows it at 100% within a split second of starting the upload), but it appears that the file never actually uploads. I tried uploading a 25MB file to Box.net, but—after an hour—it still hadn't uploaded. I did some quick research on Google and I see that there is apparently an issue with ESET Smart Security and Windows 7 that is pretty similar to the problem I am having. The suggested fix for that problem was to uninstall Smart Security. Even though I am using ESET Nod32 Antivirus, I decided to try it. Sure enough, as soon as I uninstalled the program and did a restart. Files are now uploading just fine. I'm in between a rock and a hard place here. I can't really go without an antivirus app on my PC. But I also can't sacrifice the ability to upload larger files, since this is an important part of my business. Does anyone know of any workarounds for this issue? If not, what security/antivirus product can you recommend in lieu of ESET Nod32?
