OS: W7-SP1
I just uninstalled BDIS 2015. I can't be bothered with trying to troubleshoot the Quick Scan problem of hanging on 'winhttp.dll'. System sans also appear to be hanging. Their are two 'winhtttp.dll' files on the computer and both are dated 2010. I never had a scanning problem with hanging scans on my W7-SP1 computer using BD AV Free or BDIS 2014. However, their were some update problems with BDIS 2014.
In any case since I don't use the W7-SP1 computer for very much of anything and never had a malware problem when using BD AV Free alongside MBAM 1.75 Pro (now MBAM 2.0 Premium) on the W7-SP1 computer I just decided BDIS 2015 isn't worth the problem. It only cost me $19.95 for a two year license to BDIS 2014 so I will just chalk it up to a petty cash loss.
If the 'winhttp.dll' problem is ever solved before the next vesrion of BDIS is released I might reinstall BD 2015. In the meantime I will stick with BD AV Free on my W7-SP1 computer.
Maybe I got spoiled with BD W8 Security which is by far the best AV product I have ever used. It just keeps rolling along with low RAM usage protecting my three W8.1 updated computers. A great product. Too bad I can't say the same about BDIS 2015.
