Can anti trojan act as AV?

I have Bit Defender pay version, and Ewido. At the present time the update server for BD is having problems.
Will Ewido, pay version, do a reasonable job of AV protection or is an AT good only for trojans?

I guess the fact that my BD AV is not updated for a day or so is not too serious, but am curious if there is some overlap between AV and AT.

Thanks,
Jerry

 

Only for trojans,( and some other malware ) not for viruses.

You should be okay if it is for a day or so. The overlap is that many of the commercial AV programs can detect trojans, some better than others.

So, overall, an AV will cover both viruses and trojans ( and other malware ) but an AT will cover mainly trojan detection only.

At the present time, never trust your AT program for virus detection.

 

Btw. old-style viruses (file-infectors) are almost gone (< 5%)

 

Thanks for the information.

The only 'tests' I have seen looking at the effectiveness of Ant-trojans in detecting viruses are;

1. VirusP's tests; see for example http://www.virus.gr/english/fullxml/default.asp?id=67&mnu=67

2. The esteemed Firefighter's tests; see for example https://www.wilderssecurity.com/showthread.php?t=58597

Not surprisingly, all the AT's tested performed poorly against viruses.

 

Thanks.
My AV is now updated.
Before the update it caught two of the Bagle virus trying to come in my email.
