My PC has been running a bit slow generally but yesterday McAfee reported problems with real-time scanning. Now when I turn real-time scanning back on, it flicks back to being off and won't stay on. I also cannot run a scan. The firewall has tried to switch off too but when I turn that on again, it seems to stay on (or at least it is at the moment). Could this be a virus? I'm worried because I was the victim of credit card fraud just before Christmas and wondered if that too was linked to my pc.
Thanks in advance for your help.
Edited to add: Just noticed a new weird thing... when I try to click the 'turn on' button, it flashes up a message asking if I'm sure I want to turn off real-time scanning even thought the button I press is to turn it on!
