Trustworthy Anti-Spyware Products
Protecting your PC w/ quality anti-spyware applications...


When choosing anti-spyware protection, you should rely on products with deserved reputations and proven track records. That means avoiding the new and unknown, and not succumbing to impulse buys of anti-spyware products that you see on the Net, esp. those included in the "rogue/suspect" list on this page or advertised on Google.

At the very least, you should have an anti-spyware scanner, and there are several reputable anti-spyware scanners available on the Net -- some even for free. But anti-spyware protection goes beyond having an anti-spyware scanner like Spybot Search & Destroy or Ad-aware. Even after installing and running an anti-spyware scanner, you should take steps to lock down your browser and protect your system against further infestation by spyware and adware.

What follows below is a set of recommended steps for installing anti-spyware protection for your PC. If your PC is already infested with spyware or adware, see the instructions for getting help included later on this page.
1. Run an anti-spyware scanner (or two...)
One basic tool in every user's toolbox of software ought to be an anti-spyware scanner. There are several excellent anti-spyware scanners available -- some free, some for pay. These include (but are not limited to):

Ad-aware

GIANT AntiSpyware

Pest Patrol

Spybot Search & Destroy

Webroot Spy Sweeper

Anti-spyware scanners work much like anti-virus applications (such as Norton Anti-Virus, McAfee VirusScan, et al), except that instead of scanning your PC for viruses, trojans, and worms, they scan your computer for spyware, adware, and dialers. (You can find a more complete list of anti-spyware applications HERE. And for reports on testing with many popular anti-spyware utilities, see HERE.)
I recommend using at least two anti-spyware scanners regularly, as one will often pick up items that the other misses. Even after you install an anti-spyware scanner, be sure to keep it updated because new spyware and adware appears on the Net almost daily.

scarica Webroot Spy Sweeper e fai una scansione

cmq anche se non li rimuove in automatico, Pest Patrol ti dà le info per la loro rimozione manuale
