I vote for both .
From my experience , most of user with infected system ,
always feeling angry and depressed , they don't have patient to install too much tools or programs ,
this is why i always recommend the portable version for them .
However ,
I send a email to Zemana at end of July ,
and here is my questions :
1.
Did the old portable version (v2.XX) still working ?
2.
If the portable version is already in the future plans ,
Is there any expected or estimated release time ?
And here is Zemana's official reply :
No it no longer works so it does not get virus definition of version updates.
Probably ZAM 3.0 Free(as portable) will be released on next 3 months.
From official reply , seems portable(v2.XX) are already stop update for virus definition ,
I think this will affect the results and detection rate of the scan.
So , before the new v3 portable release , i guess i will keep using them both .
By the way ,
there is still many tools can be a great second opinion scanner ,
such as HitmanPro、Norton Power eraser、Malwarebytes、RogueKiller ... etc .
but things to note , HMP isn't free , only few days for trial version .
