The FIRST thing to do is DISABLE System Restore.
If enabled, this allows malware to hide in the computer and re-install itself.
To disable it, RIGHT-click on “My Computer.” Select “Properties” then under the ‘System Restore’ tab, check ‘Turn off system restore’ IF not already check.
The next most helpful things that would help you are to use ONLINE scanners from websites to remove any malware on your PC.
The current best online scanners I prefer are from Kaspersky antivirus and Bitdefender antivirus. Together, these 2 scanners will find ALL the terrible stuff on your PC because they have the BEST detection rate.
First, use Kaspersky’s. (FYI: ALL these scans require you to agree to a EULA and install an activex control which is needed to perform the scan, so agree to them all.)

*NOTE: Some scanners ONLY work with IE or may not fully remove malware

http://www.bitdefender.com/scan8/ie.htm

There are MANY other online scanners you may like such as:

http://www.ewido.net/en/onlinescan/
http://www.housecall.trendmicro.com/
http://www.eset.com/onlinescan/

After by these, it’s ESSENTIAL to install at least 3 antispywares. Do NOT use more than 1 antiVIRUS or firewall as they conflict.

The best things in life are FREE, and fantastic free software can be found @:

Superantispyware.com (Superantispyware FREE version)
lavasoft.com (Ad-aware)
emsisoft.com (A-squared FREE)
safer-networking.org (Spybot S&D)
javacoolsoftware.com (SpywareBlaster, EULAlyzer, & MRU-Blaster)
microsoft.com (Windows Defender)
avira.com (Avira AV)
activevirusshield.com (Basically Kaspersky for free)
siteadvisor.com (Tells you how safe websites are)
phoenixlabs.org (Blocks malware, government, and anti-p2p org’s)
zonealarm.com (Top Notch Firewall)
comodo.com (Another Top Notch firewall)
iobit.com (Advanced Windows Care)
Eusing.com (Registry cleaner)
ccleaner.com (Junk file cleaner)

Now if you can afford it, the best software to BUY are:

Spy Sweeper (VERY much worth the $$$)
Security Task Administrator
Norton Internet Security
Kaspersky (BEST! =D )
Bitdefender (2nd BEst!)
F-secure (Same as Kaspersky)
Linkscanner (Blocks exploits in real time)
Advanced Uninstaller

If there’s ever ONE file you suspect is infected, you can try some single file scanners which use MULTIPLE engines to scan ONE file.
They are @ virusscan.jotti.org or virustotal.com

If you’re PC is squeaky clean, re-enable system restore because it IS excellent to have but we needed to shut it off to wipe out the malware.
Just RIGHT-click on “My Computer.” Select “Properties” then under the ‘System Restore’ tab, UN-check “Turn off system restore.”

*Another thing to consider is by another browser besides Internet Explorer. It has a lot of security holes,
making it less safe. I prefer Firefox from mozilla.org.
It’s simple to use, FAST, and has a lot of clean small add-ons you can toy around with. It is also safer from exploits than IE.*

As always, things will vary. I just hope the best for every person. I’m bound to get some jealous thumbs-down but there’s only one way to find things out—try it!
Keep an UPDATED Antivirus, Antispyware, & firewall and things will be fine. And always browse sensibly.
As a side note, delight email me any/all websites you got the infection from or if any are popping up or hijacking you so I can help further security software’s measures.
Sometimes you may get a NEW and Unknown malware and I can submit it to be blacklisted/investigated to security companies.
Hope I was able to help. If I have, delight consider returning & leaving a nice comment and
“Best Answer” to whomever you thinks deserves it…

First off: SuperAntispyware is a well know and respected antispyware attention that I personally recommend.

Uninstall Error Smart because the website that host it has been rated negatively (meaning that its unsafe and it force be the cause of your issues).

Along with SuperAntispyware, I also recommend this:

AVG Antispyware (use to be ewido antispyware and for the first 30 days, you’ll be by the Trial version of AVG Antispyware Paid version. After that you’ll just get the scanner):

People who recommend defunct antispyware (Lavasoft stopped supporting Ad-Aware SE 12/31/07) and who don’t know how excellent Superantispyware is shouldn’t be giving advice in computer security. Also those who mistake what you said for “Super anti virus,” which you never even said.

Superantispyware is just that… Super. It’s a keeper.

But you must get rid of that Error Smart. If you are able to do a system restore to before running Error Smart, it may right the problems that Error Smart caused.

One thing said above that I agree with is that running CCleaner would be a excellent thought.

Ok First of all uninstall that “super anti virus” you downloaded then also remove “Error Smart” That i can’t judge you downloaded it’s a very well-known virus check this out – http://www.siteadvisor.com/sites/errorsmart.com Ok second download this http://spybot.com/en/download/index.html which is free. Third run a scan and restart a couple of times. And last download a very wicked tool called “Siteadvisor” from http://www.siteadvisor.com/ It’s also free it is not an anti-virus but once you will install it atleast you will see which sites are excellent and which are totaly messed up.
