Advice Request How My PC got infected?

[BearHug]

Yesterday I posted Is My PC Infected?
That issue is now solved. But I'm still thinking.. How i got infected??? From many months I was using My PC cautiously but yesterday I faced the above problem [ Is My PC Infected? ] and today when i scanned my pc with on demand scanners then ZAM found 8 threats, MBAM found 34 threats, HMP found 2 threats but my main AV Avast didn't fouund anything.. I was really shocke after this.. And One More thing, From few months as I said earlier, I was using my PC cautiously. I didn't even installed anything from untrusted source.. Not a single Untrusted Software. I didn't even visited harmful website and didn't even used cracked or patched applications. Yes, Trust I didn't perform a single "HARMFUL" Task!

What do you think?? My main AV is not capable of doing the job?? Should I change My AV?? or Anything Else?

of course you need to change your AV. i do not trust avast anymore.
use another AV that has better real time protection like: kaspersky, norton or bitdefender.

Any Suggestion of a lightweight AV Which do the job but use less CPU and RAM and also updates on slow internet connection?

 

[Islam Gamal]

you have 2 choices norton or eset. they are very light and very strong against threats. use anyone of them with zemana and you will be protected very well.

You don't need to change your av and that infection isn't related to Avast!it's all about the VPN ... they are doing shady things I also found the same problems with Windscribe! not saying Windscribe is a malicious program but VPNs change internet settings in their own ways.

You can get Crystal Security and Comodo Firewall.

Crystal Security? Never heard anything about it..

It's funny some ppl suggest him to change AV. thats not true..

@BearHug Which Avast? Free Anti Virus or Internet Security or Premier??

 

[Syafiq]

Crystal Security? Never heard anything about it..

www.crystalsecurity.eu A soft anti-exe, cloud based AV(VT engines and their own engines)

 

[Daljeet]

While using Zemana it will detect little changes including DNS and mark the changes as malicious (I'm using heimdal that time)
Search coming errors @BearHug

Didn't got you..

 

[Daljeet]

Sometimes problem is very little and my meaning is check (search) threads you found in scan.

@BearHug I regard everything in the internet as not 100%safe [It more about minimising risks.). Visit a legit big news website? Maybe you got no addblocker and they got there adds "compromised " and deliver exploits/malware whatever. This has happened numerous times sadly.
Its either you invest time to get a hint of the dangers (like in the security news section here) or hope for the best in the long run

[Sunshine-boy]

I think you need to take a look at browser settings for that trace cookies problem.use a good Adblocker or some extensions like script safe.

 

[CyberTech]

Ok well the VPNs changes something like that what sunshine said, give it a chance. if your pc would problem again anytime then so change AV...it looks like mistake by Express VPN in my opinion..

From your screenshots on your other post, I saw that Zemana Antimalware mostly picked up potentially unwanted modifications, not sure about the rest of the other detections. But from that it might just be an application that overstepped it's boundaries and changed a lot of the default settings (therefore POTENTIALLY unwanted modifications).

You should try to find out the source of these changes (if not already detected by the second opinion scanners).

Changing your AV probably would not help you, the truth is there is no AV that can pick up all the malware in the world. Instead you should focus on your browsing habits to prevent future infections, such as always checking the file on virustotal before installing it, even if it came from a "trusted website".

Also there are additional settings in your AV that could potentially prevent this from happening again, such as harderned mode, enabling cybercapture, increasing HIPS and sensitivity to maximum and doing scans with second opinion scanners (Zemana, Malwarebytes, etc) every month or so.

34 threats, I would not continue with Avast, install more robust protection, such as G Data, Emsisoft or Kaspersky.
