I apparently have/had a virus or trojan on my dell laptop computer, operating system vista. i was using mozilla firefox yesterday when the website i was on froze, then mozilla shut down spontaneously. Windows began opening saying my system wasnt protected with a heading of vista antispyware 2012, and also windows security center windows and pop ups from the system tray.
From this point on, everytime i tried to open any browser or run any program i got these same warnings.
i ran mcafee and it found 2 cookies and deleted them, but this didnt change anything.
After about 7 hours of rebooting in various modes and closing unnecessary programs, mcafee apparently ran another (regularly scheduled scan) and said it found a trojan and i should reboot so it could be deleted. i did this and i am no longer seeing any security warnings, but then whenever i tried to run any programs or open any browsers, a window opened that said "windows needs to know what program created this." i have an option to choose a program or to find it online. if i click the online option, i get the same warning for the browser that opens to go online and the cycle continued.
I couldn't run malware or spybot or any other programs.
Then my son figured out the programs will open in command prompt and he ran a system restore for 2 days prior and things are opening. my concern is that the virus will come back or that there is remnants of it left. should i be concerned about this. is there any way i can find out if i am still at risk from this virus. My browsers do seem to be running slower than they used to and programs are opening up slower.
this is one of the pop ups i was seeing the first day i had the virus. unfortunately i didnt get screenshots of anything else.
if you need any other information please let me know
thank you for any help you can offer
