Here are the top to notch lists if your computer is seen with virus or spyware.
1. Back up the system on a separate storage device (an external harddrive will do)

Safe mode with Networking, as some viruses can only be removed in safe mode. To perform this, restart pc and wait until the manufacturer's logo is displayed, then press F8 continuously until
Advanced Boot Options window will come out.
3. Turn off
System Restore by going to
Start >
Programs >
Accessories >
System Tools >

Add/Remove Programs from
Control Panel to uninstall any unwanted/unverified software and other applications that you think is suspected.
5. Install a licensed antivirus software, run then update it on the suspected pc.
6. Install
Spybot search and destroy or
Superantispyware into the infected pc, run then update. You can use softwares like Spysweeper from Webroot Software, Microsoft Anti-spyware, eTrustPest Control, or Ad-aware from Lavasoft. Make sure to run and update them on the infected system.
7. Make sure you are connected to net while performing these steps. If you cannot go to internet, run LSPfix (a free utility from
cexx.org) to repair Winsock 2 settings. Perform another using your licensed software.
