I wouldn't. I know better freeware. Typically when techies have never heard of something, there's good reason for it.
Not trying to start anything,but how do you know it's no good if you have never heard of it? I've used ASC for almost two years and swear by it,along with Smart Defrag.
No self-proclaimed "techie" should overlook Iobit,imho. Their software does a good job,yet is safe enough for casual users. The registry cleaner alone is reason to use ASC.
why Iobit ? Fast , very fast for me , and cheap ( FREE ! ) and you cant get cheaper then that ... for what they do to help me keep my PC clean I would willingly pay for summat as EASY TO USE , TRUSTWORTHY AND FAST ...
P.S. Glad I helped with the OP. Thanks Mike, you made my day.
