I did some more research on your problem, and the results show that a lot of users just remove that program and go with something else. I would suggest that you try AVG with Kerio as your firewall. Be sure to only have one of each type of program running at one time:
Anti-Virus programs take up an enormous amount of your computer's resources when they are actively scanning your computer. Having two anti-virus programs running at the same time can cause your computer to run very slow, become unstable and even, in rare cases, crash.
If you choose to install more than one Anti-Virus program on your computer, then only one of them should be active in memory at a time.
There are basically two types of these programs:On-Access
and On-DemandOn-Access Scanners
As the name implies, are scanners that 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
As the name implies, are scanners that only run when you ask them to.
Online Scans and scanners that run on your machine but are not actively scanning your machine.

I do not believe that this is a malware related issue. Take your time with this, be sure to have protection in place, don't remove F-secure without replacing it with something.
