PC Security: your questions answered

The answers to your most burning security questions

At PC Advisor we're deluged with your PC security questions. So here's our guide to getting rid of spyware, shrug off spam, and staying safe on unsecured public networks.

Viruses, spyware, and worms. We all know the dangers inherent in accessing the internet, and we all take precautions. Yet our PCs still occasionally get infected because we can't know everything.

Here we'll show you how to rid your PC of nefarious, spyware-infected programs, explain why you sometimes receive strange email from your own address, and teach you how to stay safe on unsecured public wireless networks.

How do I get rid of a spyware-carrying program that won't uninstall?

The uninstaller that comes with a malicious program isn't likely to do much good. Still, you might try running it with Revo Uninstaller, a freebie that runs an application's own uninstall function, and then scans the hard drive and Registry for leftovers (there are usually some). We’re not sure how effective it will be against a malicious program, but it's certainly worth a try.

If that doesn't work, try to manually delete the program file or folder. And if Windows won't let you do that, try Cedrick Collomb's free Unlocke. Once installed, Unlocker comes up automatically when Windows refuses to delete, move, or rename a file or folder, or you can launch it from the file or folder's context menu. Also, once it's up, it shows you what processes are hanging onto the culprit and lets you kill them.

You can also try Windows' System Restore. In Windows XP, select Start, All Programs, Accessories, System Tools, System Restore; choose Restore my computer to an earlier time; and then click Next. Pick the earliest Restore Point available, and follow the prompts.

In Vista, click Start, type 'rstrui', and press Enter; select Choose a different restore point, click Next, and check Show restore points older than five days. Click Next. Pick the earliest Restore Point available, and follow the prompts.

If that doesn't work, try running System Restore in Safe Mode. Reboot your PC and press F8 just before Windows loads (you may need to try a few times to get the timing right). At the resulting menu, select Safe Mode with Command Prompt and pick your operating system. At the command prompt, type 'C:\windows\system32\restore\rstrui' (or just 'rstrui' in Vista), press Enter, and try running System Restore from there.

Another option: since you have a name for the program you can't remove, you might be able to find removal instructions via your favorite search engine. Add the word remove to your search string, and avoid any link from the company that makes the program or any site that seems to have a positive opinion of it.
