HP Advisor will not uninstall, causing laptop to be slow?

My Windows 7 Presario CQ62 Notebook PC recently became very slow. Programs take longer to load and frreze, and my internet connection seems like it's been halved. I've tried cleaning out my cache and cookies, scanning for viruses and malware, and even using CHKDSK to no avail. I think my problem might be stemming from the HP Advisor program, but I'm having problems uninstalling it. The uninstall progress bar will stop a little over halfway through at the "gathering required information" stage and stay there for about 10-20 minutes before an error message reading "Error 1316 A network error occured while attempting to read from the file C:\\Windows\Installer\HP Advisor.msi" Any advice on how to get rid of it? I've tried using the regular Windows uninstaller, Iobit uninstaller, and CCleaner and all have this problem. If you need any more information, let me know. And thanks in advance.

Iobit uninstaller,

You have just given one of the main reasons that you are having problems.
Uninstall ALL IObit programs, including Advanced System Care, and any other part of their programs.

Your system should work much better after this -

If you do need an Unstaller program then GOOGLE Revo Free uninstaller -

Thank You -

Ok done. But what about HP Advisor? Also, any advice on some good computer maintenance programs?

Ok scratch that, it said the uninstall was successful but Advanced System Care still appears on my list of programs and won't go away. Also, I'm trying to delete the excess files from the Iobit folder and windows tells me they're in use by another program. And my comp is still going slow.
