Malware issue on
windows 7 64bit Home
Recent malware issue on a client Laptop, have seen the same
issue before but ended up by rebuilding the PC.
Issue
When browsing the internet advertisements would appear on the
browsing screen.
A proxy server had been set to point to the local client.
Removal
The laptop had Microsoft Security essentials installed, when
a full scan was run no issues were found (not surprised, may have been taken
over by the underlying issue).
Installed Spybot Search and Destroy from Safer Networking,
updated and ran a full scan, numerous issues were found and resolved.
The advertisements were still appearing, some major issues
had been removed by spybot but the system was still infected.
Installed AVG free from Grisoft, AVG Free found some Trojans
and removed them.
Still the advertisements were appearing,
Now installed the free version of Malwarebytes from Malwarebytes.org,
updated and scanned the system. Even more issues found, these issues were
connected with the Advertisements (Dnscon
). Malwarbytes removed the issues, no more advertisements
and proxy redirects.
In Conclusion
If your first security tool doesn’t find an issue some
additional tools, make sure you use reputable providers and you down load from
their websites. There are some good tools, but always think why is something
free,
