PLease download, install, update, then run a full system scan with the free Malwarebytes tool below. Delete anything it finds.
When that's done, please recognize that running the Regcure program can occasionally cause such problems and if you've got an "undo" option in the program, it might be worth trying..
If nothing else fixes the issue with McAfee, their general instructions are to perform a complete uninstall from Add/Remove Programs, then run their MCPR.exe tool from the link below to completely remove all of McAfee's retail products, then reinstall McAfee. (Since you haven't told us the specific version of McAfee you're using, I'll guess you have a "retail" version of McAfee and NOT their corporate Enterprise version.)
Please note: Clicking on the link below will immediately open the download dialogue window.
Hope this helps.
First, a few specs: I have an eMachine T3418, running XP, which I've had since mid-2006. I'm updated on all the drivers/add-ons/service pacakges, etc, as far as I know.
This is by far the strangest issue I've had on my PC...especially since this happened AFTER I did my weekly run of McAfee/RegCure/CCleaner/Ad-Aware, et al. The only websites I went to after running them are Amazon, Yahoo, Live Journal, and Facebook. I ran them on Saturday without any issues, but turning on the PC on Sunday, I came into this issue.
McAfee is not running, I can't update it, and I can't reach their website (I keep getting 501 or a 504 error). I can, however, reach other sites such as Norton/Symantec, Ad-Aware, and so on, without any issue. I've run all sorts of virus checking software without any issues and they're not finding anything. I've run CCleaner, RegCure, and I'm currently running Ad-Aware as we speak. I've also run a few programs I downloaded via a different computer to check for Conficker, but they're not finding anything.
I should also add that I have no problems going to any other websites (not to worry, I'm going to ones I know are safe), though both my browsers (IE8 and Firefox) can be a bit slow, and my system has been having a few hung app issues lately as well--not many, but enough to be annoying.
Any ideas/suggestions? Would doing a system restore or even reinstalling the OS help? And are there any downloads/threads here that I might have missed that I can try?
Thanks ahead of time!!
