I used the trial version of SpySweeper 4.5 without any problems and therefore decided to purchase the full version. I am using SS solely as an on-demand scanner so I have disabled all features which load up on start-up. However, with this full version I am seeing my AV’s taking 60-90s longer to load on system bootup. This is seen with both VBA32 and KAV 6 , so is unlikely to be AV specific. Uninstalled SS, and everything is back to normal again. Webroot support suggested I use SS v 3.5 which works well without any slowdown of the AV’s loading up. BUT; 1. I am not too happy about using an older version when I presume the latest version has a number of improvements. 2. Has anyone else come across this problem with the latest version of SpySweeper and have you a different solution to the slow loading of AV’s ? It’s not a major problem but I would prefer to use the latest version of SpySweeper. Just heard again from support who have said that a new version is planned for end June/ beginning July which will fix a lot of the issues found with version 4.5.9 build 709. Let's hope the above is one of them!
