PC Tools AntiVirus
We have waited a long time to find a top class anti-virus from a trusted name that we can confidently recommend. The wait is finally over. Using Kaspersky Lab technology - widely regarded as the best in the business - with a simple, easy to use interface and ultra-low resource usage, PC Tools AntiVirus gives you protection you can rely on, at a price you can afford.

PC Tools AntiVirus provides top-class virus protection with no frills. There is a standard virus scanner that you can run on demand, or regularly at scheduled times. There is a normal scan which checks everything and a fast scan that checks only known executable file types. There is also a custom scan option that lets you specify which folders to scan. The scanner doesn't slow your computer much so it won't stop you doing something else while it runs.
PC Tools AntiVirus also has a real-time virus scanner that checks files as soon as they are written to disk or opened. This will alert you as soon as any virus arrives. Unlike other anti-virus products, PC Tools AntiVirus doesn't scan emails or web downloads while they are being downloaded. This is no disadvantage as any virus must be written to disk - when it will be detected by the real-time virus monitor - before it can do anything bad. In fact we consider it a plus, as email and web scanners slow Internet performance and are often the cause of mysterious, hard-to-solve errors.
PC Tools AntiVirus is built around the Kaspersky Labs virus scanning engine, giving you a high virus detection rate and infrequent false alarms. A powerful heuristic detector provides the ability to alert you about new, unknown viruses. The all-important updates are automatic, small and as frequent as you need - you can check for updates every 30 minutes if you want.
If a virus is found, it can be quarantined or removed. PC Tools AntiVirus doesn't give you the option to cure an infected file, but if a Microsoft Office document is infected by a macro virus then the macros can be removed.
A major benefit of PC Tools AntiVirus - which wasn't the case with earlier versions - is its ultra low resource usage. The real-time scanner and main application / user interface together use around 1MB of memory when idle, which is less than any other anti-virus product we've seen. This makes PC Tools AntiVirus unquestionably the best choice for older and slower PCs and notebooks which most other products will almost bring to their knees.
If you have been looking for a virus scanner that will make minimal demands on your PC's performance and your wallet, your search is over! Pick PC Tools AntiVirus!
