The option to increase my computer’s lock-time is grayed-out

No this is not due to any anti-virus software and is due to the group policies. You can follow the following steps to enable it, but to do it you must login to the machine using a user that has “administrator” rights.

First option is to download the “Enable Screen Savers.reg”

The browser will ask you to save the file. Press “Save” and save it to your “Desktop”. Next you have to right click on the downloaded file and click on “Merge”. Next click on “Run, and “Yes” (for Windows 7) or “Continue” (for Vista, “Yes” again and “OK” when prompted.

Now open the “Screen Saver Settings” window to apply. If its already open close and re-open.

That doesn’t suppose to happen when you select “Blank” in the screensaver. The options underneath it shouldn’t be grayed out. The only time the options are grayed out is when you select “(None)” in the screensaver because this disables the screensaver itself. If you suspect your computer is infected, try scanning your computer. Update your antivirus and perform a full system scan.

Another way is to download Sophos Virus Removal Tool and install it. Once this is installed, start Sophos then wait until its virus signature database gets updated. When updating is complete, click to scan your computer. Scanning will take an hour or longer depending on the size of the drive and the amount of data.

The tool scans everything on your computer including external devices like USB flash drive and external hard drive. You don’t need to uninstall your existing antivirus to use the tool. Sophos works alongside any antivirus program you may have. When a virus is found at the end of the scan, remove it then repeat the scan over and over until it no longer detects a virus.

Once the computer is clean, check the screensaver options again if it’s back to normal. If this doesn’t fix the problem, try using the system file checker utility. Click “Start”, “All Programs”, “Accessories” then right-click “Command Prompt” and select “Run as administrator” to launch an elevated command prompt. In the command prompt window, type without quotes “sfc /scannow” then hit Enter.

When you are prompted to insert the setup CD, insert your Windows setup CD or DVD on your optical drive then continue. The utility scans your computer’s protected system files for incorrect versions and replaces them with correct ones. When it is finished, close the command prompt and restart the computer. See if this works.
