Grisoft AVG Antispyware 7.5 deactivated 50 percent of the spyware files and Registry entries we introduced - the second-best showing among the five Vista-tested programs. Unfortunately, Grisoft AVG Antispyware 7.5 successfully cleaned only 30 percent of adware files and Registry entries.

Grisoft AVG Antispyware 7.5 is easy to use, with self-explanatory icons at the top of the main interface. On the down side, Grisoft AVG Antispyware 7.5 lacks antiphishing protection to keep you from going to fraudulent financial sites looking for personal information, and it has no POP3, IMAP or SMTP scanning to block email-borne spyware threats.

Also, you can't set a system restore point in case you accidentally delete critical files during Grisoft AVG Antispyware 7.5's disinfection routine.

AVG customers in the UK and Ireland can receive ready access, via a standard-rate phone line, to qualified engineers from a UK-based technical support team (see www.avguk.com for details).

OUR VERDICT

In the end, Grisoft AVG Antispyware 7.5 is a pretty solid program with the strongest signature database we tested, but it falls short in behaviour-based protection against unknown threats.
