The entries below indicate that you may have two antivirus programs,
Norton AntiVirus and
AVG Freeon your computer.
Norton AntiVirus
O4 - HKLM\..\Run: [ccApp] "C:\Program Files\Common Files\Symantec Shared\ccApp.exe"
O4 - HKLM\..\Run: [osCheck] "C:\Program Files\Norton\osCheck.exe"
AVG Free
C:\Program Files\Grisoft\AVG Free\avgcc.exe
O4 - HKLM\..\Run: [AVG7_CC] C:\PROGRA~1\Grisoft\AVGFRE~1\avgcc.exe /STARTUP
When you have more than one antivirus running at the same time, they conflict with each other rendering the computer vulnerable or unusable. It may even cause crashes. Please review this information:
Should you run more than one antivirus program at the same time?
Microsoft recommends that you have only one anti-virus program installed on your computer.
There are basically two types of antivirus programs:
On-Access and On-Demand
On-Access Scanners, as the name implies, run in the background all the time the PC is turned on and running. The main function of an on-access scanner is to monitor activity on your machine.
On-Demand Scanners, such as Online Scans and scanners that run on your machine but are not actively scanning your machine, as the name implies, are scanners that only run when you ask them to run.
Antivirus programs take up an enormous amount of your computer's resources when they are actively scanning your computer. Having two antivirus programs running at the same time can cause your computer to run very slow, become unstable and even, in rare cases, crash. I notice that you are using more than one antivirus program. This is very dangerous, as multiple antivirus programs can interfere with one another and actually allow MORE viruses to get through. Running two antivirus programs at the same time could lead to both of them trying to scan the same file at the same time, scan the same email at the same time and so on which could lead to conflicts.
I strongly suggest you do one of the following:- Configure only one antivirus program to enable automatic realtime scanning and leave the rest disabled most of the time.
- Go to "Start -> Control Panel -> Add/Remove Programs" and uninstall all but one antivirus program.
