Panda Software, makers of the Panda Antivirus program, started a free online antivirus scan called ActiveScan several years ago. However, this service has now been replaced by Panda ActiveScan 2.0
, which is a subscription service.
As implied by the name, it uses ActiveX, so you have to use Internet Explorer to use this scanner. You should be using an antivirus program that runs all the time and that does scheduled “deep scans,” too. (I use VIPRE Antivirus + Antispyware as my antivirus program.)
But, you should also scan occasionally with one of the free online scanners, and I mean with one from a different antivirus company than the one whose product you use every day.
Even if you’re happy with your anti-virus program and not seeing any signs of infections, you should check your system occasionally with an online antivirus scanner.
This should be a different scanner company than your regular antivirus program — just because each company has its own virus signature files and checks in its own way.
