Nisam. Dođi opet kad se dogodi neki sličan incident. Možda ga onda uklonim. 😂

Interesantan test (legit?) CCleaner & Defraggler.

https://www.passmark.com/reports/ccleaner17.pdf

Conclusions
All of the following conclusions apply only to the specific scenarios tested.
Clean machines, with no third-party software installed, will likely show significantly less benefit than what
was observed in the tested scenarios. While machines with a very large amount of 3rd party software or
limited hardware resources will likely gain additional benefits, beyond what we observed.

Disk space recovered
On average, CCleaner can recover around 3,400 MB of disk space on the first clean, and then around 600
MB in the week following. If run weekly for a year, this would give an estimated total recovered disk space
of 34,500 MB.

RAM Freed up
Across all four images, the average percentage of free RAM available (out of the machine’s total RAM)
increased from 41% to 56% after using CCleaner and Defraggler. This gives a 14% improvement, which is
a 36% relative improvement.

Boot time
Across all four images, the aggregate boot time was seen to be 53% faster using CCleaner and after
subsequently running Defraggler, 59% faster.

Browser launch times
Across all four images, the aggregate browser launch time was seen to be 5% faster after running CCleaner
and Defraggler. However, the results are sensitive to initial conditions. Likely external influences such as
variable internet latency, initial file fragmentation state & caching state also influenced the results to
increase the error margin in the test results.

Clean up time
Many of the cleaning activities that CCleaner performs can be done manually if the user has sufficient
knowledge and time. A comparison of a manual clean up, by an experienced engineer, to the automated
process in CCleaner, showed using CCleaner is 20 times faster than performing the same clean manually.

Installation time
On average, CCleaner takes 11 seconds to install.
On average, Defraggler takes 8.75 seconds to install.

Installation size
On average, CCleaner’s installation size is 29.55MB
On average, Defraggler’s installation size is 34.57MB.

Memory usage
When installed, CCleaner has an almost negligible impact on idle memory usage, at less than 16MB (which
is approximately 0.2% of the installed RAM on the machines tested).

Idle CPU load
When installed, both CCleaner and Defraggler have an almost negligible impact on CPU usage, when idle.
The additional CPU load was too low to be accurately measured.

Ahahahahahaah

Ne još. Ali ako ništa drugo, nisam ga pokretao otkad se to dogodilo. 

Ah, što da ti kažem. Borim se, nekako. 

CCleaner ti se ucita u pre-boot procesu. Znaci onog trena kad udjes u sobu gdje ti je komp on pocne optimizirati stvari. Dok dodjes do kucista on je vec sve optimizirao. Mislim jednostavno je...

Eh, kad bih uspio nekako povezati CC i tarot linije, mislim da bih se poprilično obogatio.

Ovako kompajliram Linux kernel po peti put danas.

.. + obavezno nakon optimizacije optimizirati defragglerom.. ubojiti tandem :)

koji marko, mustaša? Kako će mu se sad firma zvati, djeluje mi nespreman za promjene..

Ja sam isto mlad i bez formalnog IT obrazovanja

Jednostavno moram isprobat to čudo tehnologije. he he he

Zakačio sam ga na taskbar da mi je pri ruci ako šta windowsi zablokiraju. 

Marko, nisi sam !!!

Ma ja sam se preporodio otkad ga koristim.

Pa nemam ga na kompu dosta dugo, ali to ne znači da neću koristiti portable verziju kad mi zatreba. 😄

A summary of the CCleaner incident

Avast said that 2.27 million users had installed the tainted CCleaner versions, but that the malware collected only basic information, such as computer names and domain data.

The company later discovered that this first-stage infostealer was built as a mass-probing tool meant to identify computers on the internal networks of major tech and telecommunications companies, such as Google, Cisco, Oracle, Intel, Akamai, Microsoft, and many others.

Avast says that attackers deployed a second-stage payload to only 40 of these computers found on these highly sensitive networks.

Avast, Cisco Talos, and Kaspersky said that a (suspected Chinese) cyber-espionage group named Axiom was behind the hack of CCleaner's infrastructure.

Avast detects third malware strain

But yesterday, speaking at the SAS conference in Cancun, Mexico, Avast says it detected evidence of a third malware strain.

This new strain was found on four computers of Piriform employees, Piriform being the company behind the CCleaner app, which Avast bought in July 2017.

These infections went back to April 12, 2017, and Avast believes it was used to scout Piriform's network in preparation for the main hack that was to come over the summer.

Third malware strain is named ShadowPad

The name of this malware is ShadowPad —a multi-purpose and modular malware framework that comes with many plugins which provide various functionality, such as backdoor features, keylogging, and data exfiltration.

ShadowPad was first spotted by Kaspersky researchers in August 2017 on the servers of NetSarang, a South Korean software maker. According to Kaspersky, an unidentified cyber-espionage group injected ShadowPad in NetSarang's software and was using the malware as a backdoor into infected networks.

Avast says it found ShadowPad log files on the four infected Piriform computers. The log files contained encrypted keystrokes, meaning attackers deployed ShadowPad's keylogger plugin.

They also found ShadowPad plugins that could steal passwords from local apps, but also other tools that could download additional ShadowPad plugins.

Naravno, CCleaner v5.33 je zaražen, ostali nisu. Daj dokaz da je zadnja verzija zaražena.
