It's not that hard to run the programme manually later. As others have said, be very careful what you add to your boot menu. I don't see any way that it could possibly "hijack" your computer, but maybe some setting that made it start with boot-up and try to run a scan was what did it. I had a one-year free licence to the pro version from another site and when the year was up, it simply reverted to the free version. Simple concept, but some ungrateful people seem to think they should get better than free. I'll let it revert to the free version in six months and will use the pro version until then.
No one is forcing you to use it if you don't like the deal.
If you don't think you're getting enough for what it costs you (which is zero, remember), then don't download and install it. I don't understand why some people are complaining about the 6-month free licence for ASC6Pro. They couldn't pay me enough to try their stuff again.
I uninstalled Wise Care 365 and other software from the same company. They didn't even bother to send a "thanks for your e-mail" auto-reply. I contacted Wise Care and calmly and politely described what happened and asked for suggestions. It literally took out about half of the shortcuts in my Start menu, no exaggeration, and I have a LOT of installed programmes, so it was a lot of shortcuts it removed. #18, but why would it remove shortcuts for programmes that were still installed? These weren't orphaned shortcuts that no longer connected to anything, they were working, valid shortcuts.
