Choosing an anti-virus is a matter of personal preference, features offered, the amount of resources utilized, how it may affect system performance and what will work best for your system. A particular anti-virus that works well for one person may not work as well for another. You may need to experiment and find the one most suitable for your use. Another factor to consider is whether you want to use a paid for
product or free alternative
See BC's Freeware Replacements For Common Commercial Apps
and List of Virus & Malware Resources
. I recommend keeping and using MBAM on a regular basis.Note: mvps.org is no longer recommending Spybot S&D or Ad-Aware due to poor testing results. See here - (scroll down and read under Freeware Antispyware Products)
.No single product is 100% foolproof
and can detect and remove all threats at any given time. The security community is in a constant state of change as new infections appear. Each vendor has its own definition of what constitutes malware and scanning your computer using different criteria will yield different results. The fact that each program has its own definition files means that some malware may be picked up by one that could be missed by another. Thus, a multi-layered defense using several anti-spyware products (including an effective firewall) to supplement your anti-virus combined
with common sense and safe surfing habits provides the most complete protection.
If your computer seems to be slow, read Slow Computer/Browser? Check here first; it may not be malware
. There are reasons for slowness besides malware - i.e. disk fragmentation, disk errors, corrupt system files, too many startup programs, unnecessary services running, not enough RAM, dirty hardware components, etc. As your system gets older it becomes filled with more files/programs and has a natural tendency to slow down so cleaning and regular maintenance is essential.
