System Restore HELP!!!!?

Ok I downloaded Trend Micro PC cillin a few days ago because my old antivirus (McAfee) was expired. My computer was running slow BEFORE I downloaded Trend Micro and after I did my first scan, it removed some spyware and a trojan virus. I had to uninstall McAfee before I downloaded Micro because the programs conflicted. Well my computer was still running slow after the first scan with Micro, so I decided to do a system restore to an earlier day. This worked and my computer is running smoother. The problem is that I have to reinstall Micro and it wont let me because I have to remove McAfee, but everytime I try to remove McAfee, it won't let me because ''some components are missing'' so now I have no protection! Is there a way to unistall the remaining components of McAfee and be able to reinstall Micro? PLEASE HELP!!!!

After you install and run CCleaner then reboot and run cleaner again to make sure you got all files then try to install your antivirus.

System Restore HELP!!!!?antispyware

try downloading the components but i dont know where ._.
you can reinstall mcafee then uninstall the right way with add/remove or install avg free or avast, both good, but would recommend the paid versions of either.
ok what you have done is confuse your computer.. and what you need to do is go back to system restore and go back to the day you put in trendmicro pc. personally i would have gotten avg free edition.. you can find it at www.grisoft.com
you could try doing a system search )Start%26gt; Search%26gt; All Files And Folders%26gt; type in McAfee .click search. Let it run and right click on any files found . Sometimes a pop up might say that the files cannot be found. Don't worry about those they were deleted with in another file. After your done empty the recycle bin and reboot your computer.
You have some great answers and I hope they work.

BUT if they don't just download www.regscrub.com

Now the first option is to let Regscrub choose and clean your registty. This is safe and so do it.

The SECOND column (where YOU choose which prorams to delete) is the ONE you want.

BER careful . LOOK for just the one you want to delete and click it./ It will be gone forever.

Now you can re-install the regular way.
