you can do the following:
1. Goto Network Connections>right-click Local Area Network>Properties>uncheck all protocols except TCP/IP
2. Click apply and restart you computer.
3. Run the Disk Cleanup utility (start menu>run; in the address field type cleanmgr) and perform a disk cleanup.
Also remember that Windows is most vulnerable operating system so use a reliable all-in-one security suite. Really I have tested that without a Security solution a WindowsPC can add up 250 different infections in 53.4 secs.
Also no matter what free Av apps aren't effective.
