Glary Utilities almost delete all essential software that I have been used for long days. After download when I clean registry it may be deleted some important registry and soon after Kaspersky blocked all my essential softs. i.e. Adobe reader Pro, Microsoft office, IObit uninstaller, Internet download manager, Wifi Adapter, Photoshop etc. Then I uninstalled Glary Utilities and again reinstalled all my importent softs from backup. Now pc runs as usual.
Now you have me thinking.. Did this happen to me? Two weeks ago I installed Glary and noticed a variety of programs being flagged and blocked by my AV, almost like they were EXE injected. The assumption from some of the malware experts was that something was being nasty and injecting into legitimate programs. But now I am wondering if Glary is up to something? After this happened I formatted all of the machines and left Glary off this time around. Note - MULTIPLE AV's I tested flagged random programs/executables as malicious after this happened. I had written all of this off as source unknown, but it sounds identical to your issue.
