PC Tune up is horible. The SUPPORT is worse. It scanned my computer and recommended some fixes. While performing fixes, it screwed up my network and my computer could not connect with my server or get internet access. After wasting 5 hours with (lack of) support, they said they would email instructions to get the log files and look for the fix AND..... it would be 3-5 days. OF COURSE, a refund takes up to 2 weeks. THEY break my computer and I am suppose to be OK being down with my small business. AND to top it off, I have yet to receive the email instructions. DO NOT waste time on AVG products.
