Hi,

I was reading a thread where half the posters argued that Avast was better than AVG because it found problems that AVG didn't and vise versa.
I was wondering if it was a good idea to have both programs and run them alternately so as to be sure you had better coverage. I currently have AVG, Ad-aware SE, Spy-bot search&destroy, Zone Alarm, and Windows Defender. I update and clean regularly but am concerned about worms or malware that might go undetected by some of the programs.
(I have plenty of space and RAM, and want the best protection that freeware can provide.)

What is your opinion?

There are two problems with having more than one Anti-virus on your computer.
1). You must be careful to have only one application running real-time protection to avoid major system conflicts as well as computer sluggishness. This does require some user discipline.
2). You must be very careful to review any malware found by one AV, because these may be part of the other's definitions file, etc..

A careful and cautious user of the Internet probably only needs one resident AV, whose real-time protection will cover most of the current malware. Moreover, there are several very good on-line AV scans that can be used as a double-check, thus avoiding the pitfalls of duplicate resident AVs.

Thank you John,

I am unemployed at present and so I must make do with freeware which is anyways well rated. But as far as I understand 'real time' protection is the paid for versions only?
The free on line scans seemed like a good idea until I read the level of user commitment to the site publishers. It seemed both Trend Micro and Microsoft retain the right to access and transmit information from your computer in return for the favor, and Microsoft want you to pay in advance for anything they may decide warrants a charge. In both cases their seemed to be a lot of strings attached, but I'm unsure.

Any opinions on these or others?

AVs like AVG (and I think Avast from memory) both offer real-time protection; AVG scans downloads and E-mails and will prevent you from accepting malicious files. Free does not mean shoddy protection.

On-line scanners: many Members have used the ones listed here:http://www.bleepingcomputer.com/forums/topic3616.html

I do not mind, if I trust an on-line scanning source to scan my hard drive in the first place, for them to have some data if there is a clear reason for it. I do not use any MS application for computer security, since there are far superior ones available.

John

Dual installation is not always possible because some anti-virus programs will detect the presence of others and may insist they be removed prior to installation.

Most anti-virus vendors recommend that you install and run only one anti-virus program at a time:
Symantec's statement.
Avast's statement.
AVG's statement.
Dell Support advises the same for their systems.
