The malware you had previously could easily have affected McAfee. It would be nice to know exactly which version of McAfee you're using, (RIGHT click on the McAfee icon in the lower right corner, choose "About VirusScan" or something similar), but either way, please uninstall McAfee completely from the Control Panel/Add-Remove Programs section, including all other programs in the McAfee suite, then restart the computer.. Does that fix the problem?
If so, then try reinstalling McAfee and see if it runs correctly now.
Hope this helps.
Recently I was plagued with Antivirus XP 2008. It turned my background blue with a spyware message and popped up with windows security alert saying I have random different infections depending on which time it opened. Only giving me the option to get protection(of course I didnt lcik it, just closed it). I used malwarebytes and multiple other spyware removal tools. I run McAfee anti-virus and that initially caught some things but not all. After reading through hundreds of forums around the net I found a solution (or so I thought) I was instructed to download superANTIspyware remover. As well as vundofix. Also two other programs that I already had. McAfee would not pick anything up. Malwarebytes originally removed some tracking cookies and one adware program. Then after getting my background back to normal and almost feeling good about it, I continued to get windows security alerts any time I would scan or open the internet.(for the same spyware warning). After using SuperAntiSpyware remover, it detected multiple things and fixed them.
I no longer recieve the pop ups from windows security. BUT now my cpu performance is hovering around 50-60% and every 3-5 seconds spiking to 100% and back down. At one point my firewall asked if I wanted to allow Mcafee backup to be allowed to acces the internet and I said "allow". Not sure if that has anything to do with it. This cpu spike happens when there are no programs open and my mouse not moving.
I have multiple svchosts running(more than I had ever seen before) and I have a sneaking suspicion I am seeing more processes than I should. (all of my anti-virus and spyware removal is up to date)
Please help, what could this be!!!!
It is a Gateway dual core running Windows XP.
