One Care slows my computer to a crawl when it is on. My computer is fast when One Care is turned off. RRS feed

  • Question


    One Care slows my computer to a crawl when it is on.  My computer is fast when One Care is turned off.  I've tried to use my computer when either or both the One Care Fire Wall Protection and/or Virus protection are on.  My computer (a Dell) is impossibly slow with One Care turned on.  When One Care is turned off, my computer works at normally expected speeds.  How can I fix this?

  • Schiffmd,


    Thank you for visiting the OneCare forum for Install and Activate.


    Although this kb article provides steps on OneCare installation issues it may also help to troubleshoot why OneCare may

    be slow, in particular other real-time antimalware programs:

  • Thank you.  Did not really help.  But you tried.  I have sent an email request to technical support.  I have had to leave my OneCare turned off during much of the subscription because when it is on, my computer is a disaster to try to use.

  • I switched to Qwest. The installation "recomended " Live care. I put it in and my computer SLOWED TO A CRAWL LIKE A SLUG ON DOWNERS!! I removed this pile of c... and everything is normal.

    REMOVE IT. It's useless!!

    By the way, I did remove my expired Norton product but I kept my AVG. I don't like the fact that I can have only one virus program. I know, they say programs  "don't play well" together, but I've never had a problem.

  • Thank you.  The MicroSoft OneCare support staff sent me a long list of different operations that I might try to get things to speed up.  When I have a free hour, I will go through the steps they outlined.  That won't be for a while.  If those steps don't fix the problem, I will take your suggestion to "toss it."

  • jt3219,having AVG installed with One Care is the cause of the performance issues. If you did not use the Norton uninstall tool that could be a contributing factor as well. Having two antivirus products on a computer is useless and IS a problem because it causes performance issues as well as diminishing the effectiveness of both products. Using two antivirus products is a practice not endorsed by any antivirus provider.

  • Just so that everyone knows, I have no other antivirus program, no Yahoo! toolbar and no Google toolbar on my computer and still OneCare slows things to less than a crawl.

  • Schiffmd, if your computer is a fairly new Dell it may have McAfee installed. If McAfee was installed previously try running this tool - http://download.mcafee.com/products/licensed/cust_support_patches/MCPR.exe
